This is a summary on the status of the AGATA project. The AMB has met two times since the last ASC meeting (October 2016) and held 5 phone conferences. The minutes of the December 2016 and February 2017 meetings will be circulated with this report. List of attached documents:

Agata/AMBMin/Dec16/Final meeting minutes Agata/AMBMin/Feb17/00D meeting minutes

The “Project definition of the Advanced Phase 1” for the period 2013-2015 had all the information to reach up to 45 capsules in the set-up. It is unchanged.

ManagementStill missing the AGATA Commissioning Team Leader.

The Data Flow W.G. decided to simplify the structure. Now X. Grave is no more responsible of a Team. Guillaume Lalaire is the GANIL contact for DAQ items.

The new AGATA capsule (A-type) ordered by IN2P3 beginning September 2016 is expected in before the end of 2017. Mirion plans for delivery second semester 2017 (see Mirion schedule).

Detector RepairB009 and C003 are subject to leakage current. C003 showed leakage current after annealing. Both detectors will be sent to MIRION/Canberra-Lingolsheim to be repaired. B009 is within the warranty period, C003 is out of warranty.

CAT and Detector testingPresently the AGATA collaboration has 3 official sites where CAT can be performed and IPHC Strasbourg is as well starting to test detectors for the collaboration.

IRFU-Saclay- performed detector test of annealed capsule B001 in January 2017. Energy resolution core: 1.22 keV/2.26 keV, energy resolution segments: average 1.04 keV/2.93 keV (detector did not come back to resolution values within specs after one week of annealing, range of FWHM: 2.63 to 3.45 keV)

IPHC Strasbourg- IPHC Strasbourg group purchased a test cryostat for the use in the scanning table. The IPHC detector lab colleagues show interest to start performing test of the detectors. The installation of a capsule for test was done by two engineers from Strasbourg at IKP in March 2017. The cryo-stat was tested electronically, the annealed detector was mounted into cryostat. The Strasbourg team acquires presently the knowledge and expertise to perform detector tests at IPHC.

Uni. Liverpool- no CAT scheduled recently

IKP-Cologne- performed CAT of A014, B016, C016 successfully in December 2016 and January 2017. Per-formed test of C003 after annealing, C003 suffers from leakage current. B009 was tested at IKP-Cologne and leakage current is confirmed,

Capsule delivery table by Canberra Status 17. March 2017

Detector AnnealingDetectors A008, B001 and C003 were dismounted from ATC1 after replacing them with A012, B009, C004 in ATC1. The capsules A008, B001 and C003 have been brought back to IKP and have been annealed (5 days at 102 °C). Two capsules B001 and A008 were sent to IRFU for

CAT. The IPHC group went to IKP and mounted the third capsule C003 in IPHC test cryostat, thus, the CAT of the third capsule will be done at IPHC.

B001 was tested after annealing at Saclay during January 2017. Energy resolution core: 1.22 keV/2.26 keV, energy resolution segments: average 1.04 keV/2.93 keV (detector did not come back to resolution values within specs after one week of annealing, range of FWHM: 2.63 to 3.45 keV). The detector B001 was used to be exchanged with B009 (leakage current).

A008 was tested successfully after annealing at Saclay during February/March 2017.

C003 was tested after annealing at IKP during February/March 2017. Annealing procedure caused major damage. Detector will be sent back to Mirion, Lingolsheim.

New encapsulation developmentsA new capsule development has been performed at IKP in close collaboration with the IKP mechanical workshop on the one hand and Canberra on the other hand. The latter provided the capsule lid.The capsule cost was 20 k€ in itself, then the welding at Julich has also extra costs. The electron welding at Julich could be done 3 times at most. The design of the new capsule should enable to reuse it several times. New preamplifier plates are developed. All the work to mount a crystal in a capsule can be done now at Canberra which is faster and surer (in principle). The four capsules recently delivered are mounted with the new encapsulation. In long term this technique should be less costly than previous capsule in principle. Repairs should be cheaper and faster.

Use of the AGATA capsules and detectorsUp to now 43 asymmetric capsules were delivered and 41 capsules are available. Two capsules are broken. In addition three symmetric capsules are used for testing and as reference.

38 capsules are mounted in 12 triple clusters and one double cluster. 35 Detectors will be available for the experiments in GANIL.

Detector maintenance at GANILDetectors at GANIL are under maintenance from two issues:

-Neutron damage in ATC1 (planed capsule exchange and cryostat upgrade)-One core signal was gone in ATC9 in fall 2016.

ATC1Maintenance performed following the plans to remove the neutron damaged crystals in ATC1 and to remount new capsules. The feedthroughs have been replaced by Ti units and the vacuum getter of the cryostat have been moved to a new location to facilitate regeneration.Three Detectors of ATC1 A008, B001, C003 were dismounted at GANIL, shipped to IKP and annealed at IKP. ATC1 was reassembled with detectors A012, B009, C004 at GANIL. After reassembly the detector B009 was not operational due to leakage current via segment A4. (The detector B009 was repaired after damage and delivered in September 2016. After successful CAT at Liverpool it was mounted in ATC1.) Detector B009 was exchanged again with the annealed B001. The first test after exchange were not conclusive, the expected performance could not be reached. The A and C type capsules perform properly but B001 has an issue with segment microphonics never seen before. The resolution deteriorates by 30%. This microphonics is present as well in the segments. Presently the maintenance ongoing in week 12/13 by H. Hess and GANIL team at GANIL.

ATC9The detector C013 didn’t react to HV after repair, it is suffering a persistent issue on the HV.Last attempt was successful removing the problem. But again after mounting the cluster ATC9 in the array, while ramping up, the HV line broke down again and damages were produced inside the cryostat. The experts started to be worried, this is not considered a standard problem.Presently maintenance ongoing in week 12/13 by H. Hess and GANIL team at GANIL

We would like to mention the fruitful collaboration on detector maintenance activities established between the IRFU-Saclay team (Ch. Theisen, M.Karolak et al.) the IKP-Cologne team (H.Hess) and the GANIL team (J. Ropert and L.Menager).

Cluster Assembly

ATC12Assembly of ATC12 with detectors: A014, B016, C016 (three capsules from Germany) in February 2017 by CTT was finished successfully. All three detectors were operational, all 111 signals from cores and segments show good signals. All core and segment signals of A014 B016 and C016 were within specs in the final triple cryostat. ATC12 also passed the cross talk test measurements. ATC12 was accepted by German owners, Cluster detector was delivered to GANIL in week 12.

Symmetric Triple Cluster (STC) STC is back in operation. Is used for detector development. Broken symmetric capsule S003 was repaired and was sent to IKP in November 2016. However, S003 showed leakage current. Needs repair (under warranty).

Future ATCsATC13Assembly of ATC13 with detectors: A013, B015, C015 (three capsules from Germany) in summer 2017.

IN2P3 got the funds necessary to complete the purchase of one ATC cryostat in 2017.

AGATA Canberra meeting and matters During the last 6 months we had no AGATA-Canberra/Mirion management videoconference.

Detector CharacterizationCommissioning of the scanning table at Salamanca (B.Quintana). The characterization measurements are ongoing with the aim to get as much position resolution values as possible. Taking into account that the Salamanca scanning table does not measure just in a 1mm resolution grid but will try a sub-mm result for the final position resolution. The group is collecting redundant information simultaneously at every position to increase the statistics. This will provide a resolution that will be only limited by the intrinsic resolution associated to SALSA, which is estimated to be less than one mm.

The AGATA detector performance has shown quite stable during the period that it has been here. The detector is in perfect shape after seven months since its mounting in Cologne.The group at Salamanca has also installed an automatic LN2 filling system, which is in process of commissioning.

CSNSM is planning to install AGATA electronics on the collimated Orsay scanning table and to prepare a set of data for PSA algorithm testing.

Management Regarding the Detector WG leadership, due to the involvement of Germany on the detector activity, they requests to have a detector expert in the AMB. Only P.Reiter (IKP-Cologne) is available for the participation in the AMB nowadays.

2. Front-end Electronics

Coordination:The group meets by videoconference about once per month. There is a working group in charge of coordinating the R&D on the future electronics with regular videoconferences and face-to-face meetings –last one on January 2017–.

Status of the Electronics at GANIL:During the last 6 months the group aimed to have as many channels as possible to cope with the increasing number of capsules installed in the setup. Our present goal is to instrument 35 channels for the 2017 campaign.Presently the following electronics is available at GANIL:

24 DIGITIZER + ATCA pre-processing

12 DIGIOPT12 DIGITIZERs + GGP pre-processing

During the last 6 months the group with the support of the GANIL team have continue debugging the setup, in particular the DIGIOPT12 + GGP channels, that were made functional close to the beginning of the 2016 campaign. The following issues were tested:

Problems with the alignment of the DIGIOPT12 channels

Issues with the stability of the GGP

Issues with the Validation inconsistencies at the GGP level.

During the 2016 campaign, losses in validated data were observed on the GGP channels at high counting rates ~40-50 kHz. The Trigger Processor was validating most of the events but the GGP leaves only saw about half of the Validation. These losses were not observed at lower counting rates.The issue was discussed with the INFN-Padova group that suggested possible test measurements. The test was complex because required high counting rate in all channels. The problem was not reproduce with high counting rate in one or few channels. Finally, early this year, the test of the GGP Validation cycle at high counting rates was performed by E.Clement and the GANIL team. A very strong source in the setup and differences on validation behaviour were seen even in capsules of the same cluster instrumented one with ATCA and another one with GGP. All results were collected with explanations, sent to the Electronics W.G. and forwarded to the INFN-Padova colleagues. Shortly after the INFN-Padova group reported that an issue with Validation timeouts was found in the GGPs.

The INFN-Padova has updated in mid March the GGP firmware to cope with the Validation timeout and the alignment issues. During the visit a 60Co source data acquisition high rate test were performed with 50 kHz per channel ~ 1.6 MHz total. The results reported by INFN-Padova (D.Bazzacco, F.Recchia and X.Egea) are:

- Exclude_trigger_processor: 97% validated- Include_trigger_processor (Validate_all): 85% validated- Smooth behaviour verified up to 70-80 kHz per channels- Development started to push GGPs above 80 kHz if necessary

The local GANIL team has devoted efforts to check, tune and install the GGP DC/DC adapters To cope with the GGP stability issues.

Nowadays the system is more stable and easy to setup thanks to the maintenance interventions on several parts, in particular on the ATCA pre-processing removing the fuses sockets.

Status and Maintenance of the phase 0 & Early phase 1 Front-End ElectronicsPhase0 DigitizersPerformed by STFC Daresbury.Maintenance work is getting harder as stocks of spares are running out.The design is now over 10 years old.Completed the repair of the CSNSM test bench Digitizer on 13/03. Now delivered back to CSNSM.

ATCA:Performed by CSNSM and IPNO at Orsay.After the work of removing the fuse sockets, the need of maintenance on the ATCA pre-processing cards has been reduced drastically. Nevertheless the CSNSM group in charge of the maintenance lost in the last 2 years about 20% of the available efforts and there was a discussion on how to proceed with a limited maintenance, in particular for the older cards.On this line, it arrived a fear proposition by CSNSM and IPNO Orsay, KM Tun-lanoe (IPNO), will work with X. Lafay (CSNSM) under few conditions:

Testbench has to be operational: requires a working digitizer and pre-processing ATCA couple. The rest is mainly efforts from AGATA DAQ group that agreed to prepare the test bench.

As soon as a new broken couple is received at CSNSM, A.Gadea and E.Clément will be informed about the intervention planning.

The team will try to have actions on broken couple within one month after their reception in CSNSM.

If they don't succeed to repair card after 5 days of full time work, the card will be con-sidered broken non-repairable.

24 ATCA pre-processing couples working stable at GANIL. The 25th, couple M27 / S28, still with fuse sockets, sent to CSNSM for upgrade: removal of the fuse sockets and the voltage tun-ing.

DIGIOPT12 DIGITIZERSThe maintenance and testing of the DIGIOPT12 DIGITIZERS is being performed by J.Collado and V.Gonzalez of ETSE Valencia. The repairing of the DIGIOPT12 Cards is performed by A.Pullia at INFN-Milano.The goal of the maintenance work performed in the last months was to get operative as many Digitizers as possible. 12 DIGITIZERS now working. The 13th DIGITIZER has a faulty DIGIOPT12 Core card and has been sent for repairing. As soon as it is repaired the 13th DIGITIZER will be delivered after testing.

GGP Pre-processingMaintenance and repairing performed by INFN-Padova.To reach the number of expected channel it has been necessary to resort to GALILEO GGPs. The INFN-Padova group will lend few GGPs to AGATA while the remaining AGATA GGPs are repaired.In mid march 7 GGPs delivered from INFN-Padova:

- 2 AGATA GGPs after repairing- 5 Galileo GGPs borrowed to AGATA

During the visit of the INFN-Padova group (D.Bazzacco, F.Recchia, X.Egea) also performed the following tasks:

GGP client software update: fixes + timeout control

debug to increase the number of available channels: 9 → 13

tuning of DC-DC power supplies

faulty digitizers identified and fixed

new GGP tools prepared

updates of femul and narval libraries

60Co source data test

GTS maintenance:The GTS maintenance is being done by INFN-Padova. GTS-037 mezzanine failed recently (no answer to a ping). Contacted R.Isocrate who diagnosed boot flash burned and offered a fast repairing. GTS mezzanine sent to Padova already.

LINCO2Despite the few extra spares procured with O.C., need of repairing due to the limited total number. Now 2 broken.Issue related with the transceivers and transceivers metal enclosure. Ongoing an action on finding where to do the repairing.

EXOGAM2 Trigger ProcessorThe EXOGAM2 Trigger Processor is necessary for the 2018 campaign at GANILFirst version on a V707 evaluation card working for long time and stable.There is a GTS Trigger Processor User Technical Manual which summarizes the tests and gives information on the Trigger Processor instructions.Recent fulfilled milestone was the connection with the AGATA tree, including as well a NUMEXO board. All worked as expected. Some issues found regarding Timeouts in the GTS leaves. Playing with the Trigger Processor settings success to get ~98% validations in ATCA leaves. No Validations from GGPs seen, probably due to the observed Validation timeout issue in the GGPs, now probably solved.

Mechanics is being design to be able to work properly with the Trigger Processor in the setup and getting a more “professional” device.

Several persons working at GANIL on testing and completing the development, F.Saillant, A.Boujrad, and the EXOGAM2 and AGATA local teams.

Discussion on increasing the people with know-how on the trigger processor and on exploring the possibility to extend the GTS protocol to more than 255 channels.

L.Charles (IPHC) will evaluate the possibility to contribute with his group at IPHC.

Possible (very limited) contribution from UK (STFC) unless a new construction grant for AGATA is approved.

Electronics production and R&DProduction of new Batch of DIGIOPT12 Digitizer + GGP Pre-ProcessingDigitizersDIGIOPT12 cards already ordered by INFN-Milano. Delivery in summer after testing.

Control Card Production started: Routing of the Control Card updated (there was an error in the old one) now

EDA-02482-V3 Purchasing order for the PCBs placed. Assembly information sent to the mounting company some items need extra information

and costs are being evaluated.

Mechanical parts: All external boxes including the front panels are procured or produced. Crates are procured. Pro-duction of heat exchangers and cooling plates on-going.

GGPsFPGA order placed by Milano, will be delivered in 1 week.QSFP transceivers already procured (IKP Cologne).

Regarding GGP mounting, a big order is to be placed in Padova by R.Menegazzo and another one in LNL. Evaluation of the cost on-going before starting the tendering procedure.

R&D on ElectronicsDelay on the prototype of the concentrator, received in Valencia on 23 rd of February, tests to be started.Rest of the hardware to be decided.New version of the working document expected in April 2017, with the proposal on the hardware.TCP and UDP protocols under evaluation.

3. Data FlowHardware:New Hardware available at different places, 7 servers devoted to GGPs are at GANIL, 3 at CSNSM. They correspond to replacements of obsolete DAQ servers.

Disk ServerRemoval of the old disk server (needed the space). This server uses a huge amount of space in the DAQ/Electronics box and in any case has to be removed before the start of the physics cam-paign in order to install a spare disk in case of CEPH failure and to install new servers to host

GGPs in order to reach 45 channels .

A spare disk storage system is to be purchased under the DAQ maintenance cost 2017.

The proposal is to remove the GPFS cluster (which is now very old and out of maintenance) and replace it by a standalone disk server in case of failure of the CEPH cluster. The option is hence a small disk capacity which will not affect the current bandwidth One has also to keep in mind that the upgrade of the CEPH cluster itself has to be performed later (after the campaign) and that can be discussed in more details regarding the timing and the funds (OC versus CORE)

Data Acquisition software : from NARVAL to DCODDAQ box with DCOD: Upgrade of the DAQ system to DCOD ongoing following the plans of the W.G.Now PSA data bases uploaded very fast (less than 10 second to load 32 crystals) is a feature of DCOD. Several acquisition runs have been performed with 60Co source with 26 crystals (AGATA solo). A comparison between data with NARVAL and DCOD has been performed (by Li Ho-gjie and A.Korichi) to check the data Integrity. Update of the actors in the VAMOS system in order to perform a new test with VAMOS+AGATA under DCOD will be performed in the next coming months.

For the moment, when using DCOD with AGATA-solo, there is a loss of about 10% of data (to be compared with the 5% of NARVAL) as observed in the timestamp. The loses are related to the writing of the histograms into disk but could also be related to buffering size definition. Ac-tions regarding this issue ongoing.Completion of the installation of DCOD at GANIL is foreseen within March.

The event builder is ready to be implemented on line. However, when testing the system with 32 crystals some problems appeared and a delay in the final implementation is probably expected.

LINCO driver has been compiled with the last version of the Debian Operating System. The testing was conclusive for almost all ANODEs that are upgraded using the latest OS and made them all identical for an easier management.

Trigger soft validation with DCODSome issues with E Annex of ADA (Distribution systems: using multiple partitions working cooperatively as part of a single ADA program) have been solved and some progress were made. Trigger works with 3 crystals using simulated data but problems were encountered beyond 8 crystals.Next steps: understand the problem, define the relevant tests to be done with the simulator be-fore real test online. This will probably happen after the first physics campaign.

Run-Control, GCC Topology Manager and GECGlobal Electronic Control and Topology Manager are being upgraded.Implementation of new software, removing the use of scripts (user friendly).Ongoing the modification of the RCC and TM in order to control DCOD with the RCC.

A general AGATA display and AGATA control has been produced. The electronics status will be included. The figure below, shows the GUI as tested (for several functions) at GANIL in February 2017. It needs further improvements (underway) but it shows the achievements in the DAQ system compared to that of using scripts. The features/functionalities that are /will be available in the final interface are:

GTS in main interface Anode interface :

-Add launch /kill/restart DCOD_launch on all anodes and knodes button -Add functions "mount -a", reboot Anode status handle/check

Stopping a task Reload topology Carrier interface → add buttons to

-remove "fake back pressure" (script bp_error_end_of_alignment.py) -display get_rate (Synchronisation failed or back pressure or ...)

Adding reset gts tree button Change the GGP color when gts_server is on GTS interfae : function reset GTS GGP interface : function reboot anode

Data Storage

New opportunities are becoming available, more users friendly compared to our GRID storage. CC-IN2P3 experts think that we should investigate other options with iRoDS for example.

DocumentationDocument describing the sequences to start the system has been produced by GANIL staff. The validity of the sequences has been checked, by the data flow Working Group, in order to ensure the correct setup/start of the system and hence avoid DAQ-crashes.

AGATA-NEDA/DIAMANT coupling: Following a discussion with the GANIL people in view of the integration of NEDA/DIAMANT in the AGATA-DAQ-box (due to the problem of the GTS), it was decided that finally GANIl-DAQ will take care of these ancillaries. The group to setup the proper bridges in such a way that all GTS leaves are seen/integrated in scgw3 that handles the GTS setup.

Management and new membersAs commented in previous occasions, X. Grave is no more responsible of the DAQ Team. New organiz-ation of the data flow working group has been set by promoting a local «coordinator». The functions of this coordinator insures the communication between the local users, the local support and the «experts». This is a good way to synchronize / organize the needed discussions / meeting / work week with the data flow WG.

Guillaume Lalaire is the GANIL contact for AGATA-DAQ WG. The group organized a meeting with G.Lalaire to define a local Hardware/ Software coordination. Documentation for the set-up/control/check has been produced by the data flow WG and now the GANIL staff is opera-tional for the local small interventions when needed.

Patrick Le Jeannic (IPNO) in a new member of the AGATA data flow group in replacement of Yann Aubert. Several options were discussed within the group to make him operational as fast as possible- Note that Patrick is both developer and Admin system and network expert. A visit to GANIL has been organized in order to see the whole system (electronics, computers, infrastructure …). He will participate to the construction of a mini-AGATA-DAQ system at Orsay (this is planned for the test bench of the electronics and scanning). Benjamin Preciado (IPNO) will also be part of the team but remains to be formalized / con-firmed.

In summary, the data flow WG is very active on site or remotely. Several visits to GANIL hap-pened this year for the upgrade of the system and two other visits are scheduled in the next com-ing weeks for the GEC upgrade and check-up of the system before the beam-time.

4. Infrastructure and Complementary Detectors Detector InfrastructureLV cables: Present cables are rigid and heavy and they are considered an issue now that the number of detectors is increasing in the set-up. Problems with the big Jaeger connectors that get unsoldered

to cables because of the cable stiffness and their weight. Discussions are ongoing with the company. Managed by A. Lotode from IRFU.In addition few extra cables are needed to complete the 15 Cluster infrastructures.

Autofill: IRFU-Saclay informed that it is necessary to procure a new PC for the Autofill GUI/control within the maintenance of the system.The Working Group needs two years to work on the new autofill. It should be decided late 2017 if AGATA moves to LNL in 2020. To be checked if this upgrade can be done before the approval of the new MoU.

Mechanical Infrastructures The 15 alignment rings available have been checked at GANIL and some obsolete components have been removed. Now ready to receive new ATC’s

Complementary InstrumentationThe integration work of FATIMA and PARIS has been followed by the team.

Now focussing on the status of the integration of NEDA and DIAMANT for the 2018 campaign.

Document on Host Laboratory InfrastructuresPrepared a short version of the Host Lab. Infrastructure document with 3 pages. Has been dis-tributed to the ASC.

5. Simulations, Experimental Commissioning and Performance

AGATA SimulationsNew simulations performed by M. Labiche about efficiency and P/T -following the conclusions of the AGATA-GRETINA workshop- to be compared to experimental data from GSI.Dead layer close to the contact and at the back of the crystal are now considered. He plays with both parameters in the 0.6 mm to 3.4mm range. Gets about 2-3mm central hole radius increase! Not very sensitive to the thickness at the back of the crystal. This fits with M.Ginsz PhD work in which the central hole diameter is at least of 15mm (increase of the radius by ~2.5mm). For the passive layers matching the experimental efficiency the P/T value does not match.There is no back and central hole passive material thickness which fits the experimental P/T values which are too lowThe feeling is that it is more an arbitrary reduction of active material. It does not seem meaningful to add passive layers in addition.

How the position of the capsule changes when cooled down is also being evaluated.

Discussion on-going on the effect of the segmentation and the fields due to the segmentation and pasivated zones between segments.

AGATA PerformanceThe performance team aims to finalize, write a report on the last performance source measurements performed at GANIL, and possibly an article, C.Michelagnoli is preparing a template.Discussion still ongoing, still issues regarding measured and simulated efficiencies.

Two reports received by the AMB and ACC on experimental data, in particular one from the experiment E661. The group claims an efficiency loss by a factor 2 in coincidence.Discussions and analysis ongoing, nevertheless, the E661 is a fission experiment and used close AGATA geometry. In that close geometry the efficiency is strongly dependent on the multiplicity. It is well reported in the Conceptual Design NIM paper (see Fig. 7 and 10). Fission experiments have multiplicity about 20 or more (considering the two fragments). New simulations will be performed with high multiplicity in E661 experiment geometry (distance to target of 13cm).

ManagementStill looking for a leader for the commissioning team.

6. Data analysis, tracking and PSA

Pulse Shape Analysis and TrackingRegarding ADL, lot of work ongoing at Uni.Liverpool and IKP-Cologne. Using different de-tector geometries -i.e. Segmented well detector- gives a good insight on mobility parameters. It seems it is more sensitive to mobility parameters.

The working group team on PSA and Tracking is active.A number of aspects are being discussed in the teams, also in connection with the actions and conclusions of the AGATA-GRETINA data analysis workshop.Following the outcome of the AGATA-GRETINA Workshop, scanning data is to be used to in-tegrate two interactions in a segment from single interaction data. Presently all collimated scan-ning data are collected with non AGATA electronics. The only scanning table using AGATA electronics is at Salamanca and uses the GSI type PSCS technique. Traditional scanning data will be collected using AGATA electronics ASAP.A.Lopez-Mertens discussed with the team the tracking on AGATA and the impact of position uniformity on the algorithm performance.An AGATA simulated basis data set is being generated in collaboration with LBNL using Sig-gen and the Gretina methodology. This will allow AGATA data to be replayed through the GRETINA signal decomposing algorithms in order to facilitate multiple interaction in a segment PSA. The motivation can be found in the AGATA-GRETINA meeting report below.

Data Analysis:The user documentation and howto files are being kept up to date and merged with the “Documentation” project - see later.The “Cubix” software is now available. Cubix is an adaptable spectroscopy analysis tool (G. Macquart, J. Dudouet). It is an “automatic” data analysis software toolkit, that was originally

developed for AGATA-VAMOS data, there are already a few people interested on using it for AGATA gamma data alone.

O. Stezowski is working on the GRETINA to AGATA data format translation. The AMB acknowledges the work being done by T.Lauritsen, A.Korichi and O. Stézowski making possible to share the analysis software of AGATA and GRETINA.

Workshop on AGATA-VAMOS data analysisThe AGATA-VAMOS campaign Data Analysis meeting took place at GANIL on October 17th 2016. It was organized by Emmanuel Clement and major contributions came from the local GANIL team. There were approximately 6 attendees, some of the group were at the level of publishing, some just beginning and this was reflected in the content of the workshop.

The focus was people analysing the experimental data from 2015 and 2016 (one experiment only). There were very detailed discussions on the analysis of both AGATA and VAMOS. A presentation on the work done on AGATA analysis by R.M. Perez.For VAMOS, the basic data analysis procedures were discussed as well as the final refinement of the analysis.In general there was a very positive response, it will be necessary to have another meeting sometime in the future.

AGATA-GRETINA Workshop on Data Analysis The AGATA-GRETINA Data Analysis Workshop was organized by A.Korichi from the AGATA col-laboration and T.Luritsen from the GRETINA.

Programme and Slides are available on web site:https://indico.in2p3.fr/event/13409/other-view?view=standard

Among several presentations, A.Gadea and A.Macchiavelli gave the two array reports, there were Host lab. reports from GRETINA and AGATA campaigns in US and Europe, also presentations on imple-mentation and performance of decomposition algorithm and tracking, on Angular distribution and polar-isation and on detector developments with the point contact detector.

The PSA algorithm developed by D.Radford –in use at GRETINA- was compared with the AGS used on AGATA. Even if the former can de-convolute multiple interactions, the results of both systems are very similar even with severe differences on the complexity of the algorithms. It was suggested that the real question is the sum of uncertainties –data bases- and how the de-convolution is done.GRETINA uses modified GRID bases with different spacing on region with higher sensibility while AGATA AGS is using fix grids.Reported that GRETINA grid search is expected to work very reliably with ideal database. i.e. when the different parameters (impurity density…) are under control. Expecting that GRETINA (D.Radford) al-gorithm in an interaction analyzed with “correct” bases will provide a perfect result.D.Radford discussed that a possible source of error could be the cloud of moving charges generated while collecting the charge. Actually the size of the Cloud at the collecting point could be up to 5 mm.

Regarding Tracking, the GRETINA and AGATA tracking algorithms, they have been compared using an AGATA source data-set by A.K and they seem to be equivalent from the results presented. It was how-ever, decided to make an event-by-event comparison for the final conclusion (this on going)

The main outcome of the workshop is the definition of a plan to work together. Agreed that not able to reproduce the measured efficiencies. Decided to introduce more realistic constraints in our simulations, including the cryostat and environ-ment in the simulation using CAD files.

Tracking in US and Europe are based on different parameters (scattered energy or scattering angle for the figure of merit evaluation) but get the same performance.Backtracking give good P/T and OFT large efficiency. Some ideas came out to combine both algorithms to improve global performance.

All agree that the major limitation is coming from PSA/decomposition. They might be factors not under-stood. Uncertainties on energies, positions,.. These info should be passed to the tracking to improve the final response. Need to improve the pulse-shape basis. David Radford suggested performing an event mixing. Scan single interaction and mix two interactions in the same segment and use the signal decom-position algorithms to check results. Possibility to check an ideal de-composition algorithm even if the process is very long. Problems using different electronics used on the different scanning tables. Their response has to be eval-uated.It has been shown that t0 is very important for PSA. Misalignment may destroy the PSA response.

Actions defined: Summary report A.Korichi and T.Lauritsen delivered.

C.Michelagnoli and H. Crawford are working with superpulses for the crosstalk comparison

O. Stezowski and T.Lauritsen to translation of data. Olivier GRETINA into AGATA and T.-Lauritsen AGATA into GRETINA. AGATA PSA is very simple vs the US one. AGATA basis is Cartesian and US is not.

Effect of temperature on pulse shapes along a filling cycle, or before and after pumping the cryo-stat (may vary by 10K!!). Seem to have an important effect on pulse shape. Following PR, the mobility changes is slower with increasing temperature. The design of the cryostats is done to prevent big changes. The temperature change in the array is presently measured and can be ex-tracted and correlate to pulse shapes before and after a filling.

Cross-talk effect and charge cloud size to be checked.

Decision that the volunteers meet via VideoConference each two months. Next AGATA-GRET-INA data analysis workshop will be held in France on April 2018.

Exchange on experience of the two communities.

GRETINA PSA must have other sources of uncertainty to get same result than AGATA with a much simpler PSA. Replay AGATA data in GRETINA standard to be able to pass them in the GRETINA al-gorithm and get final result.

7. AGATA-GRETA bilateral Committee of Experts

The GRETA collaboration got a request from the DOE to settle a collaboration committee between GRETA and AGATA communities. A joint gamma-ray tracking detector technical working group (P.

Falon) is proposed. Regular videoconferences every 6 months will be organised to share about technical issues and developments. AGATA-GRETA meeting could even be organised if needed. Agreed at the AMB and ASC levels and now being organized.

Proposed Group on the AGATA side:• Chairperson of the AMB & Front-end Electronics: Andres Gadea • Detector Module: (Peter Reiter)• Data Flow (DAQ): Amel Korichi• Data Analysis/ PSA/ Tracking: Andy Boston • Infrastructure: Benedicte Million • Performance, simulations: Francesco Recchia • Chairperson of the Steering Committee: Gilbert Duchene

Proposed Group on the GRETA side:• Augusto Macchiavelli Torben Lauritsen Dirk weisshaar David Radford Mike Carpenter Mario Cromaz

8. General Documentation for the AGATA users

The goal of this activity is to have a document that allows AGATA users to run an experiment and perform the data analysis in a coherent manor Revised the existing documentation: Installation of the software and actors, data analysis programs etc…

There is comprehensive coherent documentation available on data analysis but for the local level processing the story is more fragmented:

Documentation originally from D. Bazzacco produced at the end of the AGATA @LNL campaign describes the electronics at that time and towards the end has sections on how to extra the x-talk coefficients etc.

R. Perez and H. Li have produced material for the AGATA Data analysis school that took place in GANIL in late 2016. This included common problems associated with cross-talk, time alignment etc.

Natasha has produced notes on the difficulties encountered with the AGATA system and some specifics on issues with ancillary systems such as the Prespec packages.

N.Lalovic produced a document on n-damage correction. Hongje Li and R. Perez produced document on the calibration, cross-talk coefficient generation and treatment of missing segment.

J.Ljungvall and O. Stézowski will collect and merge existing documentation.A. Korichi and A. Boston are involved in producing this document. Soon a draft document will be circulated to experts.The next videoconference will be on documentation of Local Level Processing, Data Building and Tracking.

Ancillaries require an extra work and have to be done after the AGATA part is completed. Ancillaries are important because heavily used in the coming campaigns.

Expected to circulate the document draft on mid April.

9. The GSI campaign

There has been nothing reported on the GSI campaign in the last 6 months.

10.Status of the GANIL set-up and campaign

Status and news on the set-up Detectors: (for more details see Detector Module W.G. section)Presently 9ATC and 1 ADC are installed in the array, they are cold and operational. All channels are taking data. ATC1 and ATC9 are under maintenance and ATC13 has been delivered recently. 38 Crystals are on-site.

Electronics: (for more details see Electronics W.G. section)Setup check and aligned with 24 Digitizer + ATCA, 10 Digitizer (DIGIOPT12) + GGP and 1 AGAVA. After the March installation expected to increase the number of Digitizer (DIGIOPT12) + GGP to 12. (11DIGOPT12 have been validated during the visit, 1 has a power issue easy to solve; 13 GGP validated)

Maximum of electronic channels is therefore 36.Several detailed tests have been done using the very intense 60Co source of GANIL. (~80 kHz/core à 2 meters). The main goal was the study of the validation rate of the GGP vs ATCA with and without the trigger processor at high rate. We could reproduce the problem observed during the in-beam which was not revealed during the standard source measurements. Report of the measurements have been sent to the electronics Working Group and distributed to the responsible group at INFN-Padova. Proposed corrections have being applied during the firmware upgrade in March and have corrected most of the observed problems

Very first tests with the new Trigger Processor of EXOGAM2 have been performed in the AGATA setup. Obtained the same validation rate with the ATCA GTS Leaf as when using the AGATA Trigger Processor. Issues with GGP to be checked again after the March upgrade.

Data flow: (for more details see Data Flow W.G. section)There had been tests of DCOD almost fully successful. AGATA actors are validated but the ancillary libraries not yet operational. Otherwise no problem to report on GCC, Topology, CEPH and Narval.

Coordination on physics Campaign and PACThe beam schedule has been released by GANIL. Five experiments will be performed between May and July. The AGATA experiments are :

A. Jungclaus [4/5 to 11/5] : AGATA + Annular DSSD P. Regan [22/5 to 27/5] : AGATA + FATIMAP. John [28/5 to 6/6] : AGATA+FATIMAW. Korten [17/6 to 27/6] : AGATA+FATIMA+VAMOSS. Leoni [10/7 to 24/7] : AGATA+PARIS+VAMOS

As a general guide line April will be devoted as much as possible to setting the experiments ie calibration and check of AGATA, installation of the DSSD and FATIMA.

Data transfer to GRIDThe data back-up on GRID has continued till completion.Soon will be necessary the replacement of the GRID machine which is aging.

Local effortsSince C. Michelagnoli is no more at GANIL, E.Clément and LI, Hongjie are doing all the tasks and the involvement of the technical staff is increasing.For the duration of the measurement campaign, the GANIL team and the local technical staff are preparing a detail schedule. It is a very dense schedule very tricky to manage on the technical work aspects. No time for upgrades as soon as the beam time starts, it will be only management of emergencies. CNRS approved a two year post-doc starting in summer 2017. This person will lead the Nwall+NEDA campaign and follow Li Hongjie work on PSA.

Exploitation TeamE.Clement local manager at GANIL suggested coordinating the exploitation of AGATA data on both the data analysis point of view and the AGATA running. The idea would be to spread the knowledge on how to run the experiments on core members of the collaboration.The knowledge is transferred generally to non permanent personnel (post-docs, students). The idea would be to transfer this knowledge to permanent personnel. Year 2017 would be a good occasion to do that because no major upgrade of the system is foreseen.He is willing to take over the coordination of such exploitation group. The idea would be to start with few French collaborators.

Installation PaperInstallation paper prepared late 2016. The manuscript was sent to NIM A on 8th February. The response from the referees was positive. No major issues. The only problems was that one of the referees considered that after 2 years, it should be possible to compare the simulated efficiency with some measurement.After receiving the referee reports, the photopeak efficiency at 1.408 MeV from the single core spectrum (no Addback, no calorimeter and no tracking) in nominal position from the 2015 source measurement (24 capsules) was added to the paper and scales with the GSI values both from the experimental and simulation point of view. It was decided to not merge the installation and performances papers. The installation paper was re-submitted on the 16th of February. The publication was accepted on 27th of February without further corrections.

Schedule for preparation of the next experimental runThe goal is to prepare a set-up with 35 detectors for the experimental run.All the actions are scheduled in the attached (Annex I) plan.
