Inner Detector (ID)

The Inner Detector (ID) is organized into four sub-systems:

PixelsSilicon Tracker (SCT)Transition Radiation Tracker (TRT)Common ID items

25th October 2004


Inner Detector Progress Summary(more details on the following slides)

Pixels: Steady ‘on-schedule’ progress on all aspects of the sub-system

SCT: Module mounting (‘macro-assembly’) on thebarrel cylinders has now started (216 modulesassembled and 203 tested on the cylinder)

Module mounting also started on the forward disks

The specific support bracket and harnessesproblems reported earlier in the year are solved,on-time component delivery for the moduleproduction is still critical in some cases

TRT: Barrel module mounting into support structureis progressing on schedule

End-cap wheel production now also smooth asthe web circuit situation is very much improved

The schedule for the Inner Detector remains a worry, withoutany float left (critical path: all SCT, and second TRT end-cap)

SCT barrel cylinder

TRT barrel support with modules

25th October 2004


ID updates – TRT – 1

The TRT barrel continues to make good progress, the second layer of modules is now also integrated into the support structure (see previous slide)

The FE boards for layer one are being burnt-in presently, and the first modules have been tested successfully with the final electronics Beam tests with barrel modules give confidence in the performance with the final electronics

TRT barrel test beam track

25th October 2004


End-Caps: The web circuit situation continues to improve and is not limiting anymore

The first wheel is now on the stacking table in SR1

The delivery of the wheels for the second end-cap remains the critical Parameter

The wheels for first complete EC are expected to be at CERN by November 2004

ID updates – SCT – 1

The barrel module production is very near completion

The first 216 modules are mounted on cylinder B3 in Oxford, 203 tested and cooled successfully

Cylinder B6 will be ready for module mounting end of October (with repaired harnesses)

Both B4 and B5 are also making good progress and follow the revised schedule

25th October 2004


ID updates – SCT – 2

The end-cap module production has passed 30% (44% started), with a yield above 90%, the

production rate however still has to improve (now at 80% of required speed)

3 SCT disks are now ready to receive modules after services mounting, and the module mounting

is indeed on-going

There is good progress with continued disk machining

ID updates – Pixels

The 2nd and 3rd lots of PIXEL chips (each 48 wafers) have excellent yield, above 80% Two more lots are expected (Oct/Nov) and we hope for similar solid yield performance

More than 140 modules have been built with the FEI-3 chips (not all modules tested yet)

Power supply

A series of Production Readiness Reviews (PRRs) took place over the recent months for LArelectronics components, in particular for the FE boards and the power supplies which are on the critical path

Special comments:- The rad-hard ST negative voltage regulators have still a delivery delay- The rad-tolerant low voltage power supplies are finally in fabrication- The BE electronics system (including RODs) has accumulated a few months delay- A new problem was encountered very recently with a special timing circuit (QPLL, part of the common CERN TTC system components) which means that FE board production is currently stopped highest priority to be solved

Detailed installation and commissioning plans for the LAr electronics have been prepared

Tile Calorimeter

Module construction and instrumentation have been finished since more than a year, and in the meantime the pre-assembly and dis-assembly of the barrel and extended barrels (EB) have been completed

The lower part of the barrel Tile Calorimeterhas been installed in the cavern already earlierthis year, and is ready to receive the LAr barrelcryostat in the next days The electronics components are in fabrication,

the assembly into the ‘drawer’ system with allon-detector circuits is now progressing well(was flagged as a critical issue at the last RRB)

25th October 2004


Extended Barrel Tile Calorimeter – LAr End-cap load and assembly test

A successful test was made in Hall 185 for the assembly of the ATLAS Calorimeter End-caps

- 273 Tons loaded to simulate LAr End-cap weight- Deformations and measured forces well within calculations (on the safe side)- Important exercise for the later EC cryostat installation and alignment

25th October 2004


Muon Spectrometer Instrumentation

Precision chambers:- MDTs in the barrel and end-caps- CSCs at large rapidity for the innermost end-cap stationsTrigger chambers:- RPCs in the barrel- TGCs in the end-caps

The Muon Spectrometer is instrumented with precision chambers and fast trigger chambers

A crucial component to reach the required accuracy is the sophisticated alignment measurement and monitoring system

Level-1

The level-1 system activities (calorimeter, muon and central trigger logics) progressed with thefinal ASICs developments and with testing full-functionality prototype modules

Design work and prototyping work is now almost completed, production has started for some items

Some – not yet critical –delays occurred for thecalorimeter trigger, partially because of implementing various technical improvements

The muon trigger electronicshas been tested with 25 nsbunched test beams, and somefinal improvements are now implemented in a final iteration

On the critical path is the on- detector muon electronics (RPC and TGC ASICs)

The Central Trigger Processorsub-system was modified to include important improvements for the trigger combination flexibility, benefiting the physics selection

HLT/DAQ/DCS

The HLT/DAQ/DCS work has now proceeded within the approved framework of the TDR, and within the responsibility and cost sharingendorsed by the last RRB

The HLT/DAQ community works heavily in the 2004 Combined Test Beam as well as in test beds for optimizing the final design

The next major milestone will be a ’10%’ set-up at Pit-1, planned for the end of spring 2005

It is recalled that an important criteria in the choice of the HLT/DAQ architecture was theability to scale the system for staging needs during the initial running of ATLAS

Components of the DCS are in fabrication, and the DCS is already in use at test beams and construction labs

Data Challenge 2, initial plans

DC2 operation in 2004:

- Distributed production of (>107) simulated events in May-June ( was delayed to July-Sep.)

- Events sent to CERN in ByteStream (raw data) format to Tier-0

- Reconstruction processes run on prototype Tier-0 in a short period of time

(~10 days, “10% data flow test”)

- Reconstruction results distributed to Tier-1s and analysed on Grid

Main “new” software to be used (wrt DC1 in 2002/2003):

- Geant4-based simulation, pile-up and digitization in Athena

- Complete “new” Event Data Model and Detector Description interfaced to simulation

and reconstruction

- POOL persistency

- LCG-2 Grid infrastructure

- Distributed Production and Analysis environment

Major goals:

- Use widely the GRID middleware and tools

- Large scale physics analysis

- Computing model studies (document end 2004)

25th October 2004


Summary of major concerns, and points of special attention

Construction issues and risks

A list of these issues is monitored monthly by the TMB and EB, and it is publicly visible

on the Web, including a description of the corrective actions undertaken:

http://atlas.web.cern.ch/Atlas/TCOORD/TMB/

The list is also regularly reviewed and discussed with the LHCC referees, and the major

entries are currently

- Delay of the Barrel Toroid coil integration (heat shield schedule, vacuum vessel

integration) now progress as expected, two first coils tested (see next talk)

- End-cap Toroid cold mass assembly (contractual situation unblocked, need to

follow the progress now)

- Macro-assembly of the barrel SCT (delay legacy because of brackets repair and

the harnesses problem, but progressing well now)

- End-cap SCT schedule for assembly of modules onto disks (good recent progress)

- TRT on-detector electronics boards and end-cap schedule (delay legacy from the

webs, again progress very satisfactory now)

- LAr FE board production delayed because of recent TTC QPLL problem

- There is also a list of open engineering issues for the overall

integration, and which are worked on with high priority

Technical Coordination is working on optimizing and updating the schedule taking into accountthe by now better known and consolidated BT construction schedule

25th October 2004


ATLAS submitted two Letter of Intent to the LHCC in March 2004

Both LoIs have been well received by the LHCC, and ATLAS was encouraged to proceed withthese activities

Other recent and forthcoming activities within the ATLAS Collaboration

At this stage the RRB report concentrates largely on the construction status and the preparation for the initial detector, however it is worth to list at least some of the other activities

- The coordination and planning of the commissioning of the detector, as it arrives in the cavern, is now operational, and takes already a prominent place in the ATLAS discussions and activities

- The Authorship and Publication Policy is being elaborated in a Publications Committee and the Collaboration has approved an Authorship policy

- The Collaboration is entering, albeit in a very early stage, the planning phase for how to run and operate the experiment in the future

- The Collaboration has also set up a steering group to ensure coherence and efficiency for future high-luminosity LHC upgrade R&D activities

The next large overall ATLAS Collaboration meetings which will be held outside CERN have beenfixed for

Cost to Completion, and initial staged detector configuration

The Cost to Completion (CtC), which is defined as the sum of Commissioning and Integration (C&I) pre-operation costs plus the Construction Completion (CC) cost in addition to the deliverables, andfunding to cover them have been an important matter at all the last RRB meetings since a few years

The following framework was accepted at the October 2002 RRB (ATLAS Completion Plan, CERN-RRB-2002-114rev.):

CtC 68.2 MCHF (sum of CC = 47.3 MCHF and C&I = 20.9 MCHF)

Commitments from Funding Agencies for fresh resources (category 1) 46.5 MCHFFurther prospects, but without commitments at this stage (category 2) 13.6 MCHF

The missing resources, 21.7 MCHF, have to be covered by redirecting resources from staging and deferrals

The funding situation will be reviewed regularly at each RRB, and is expected to evolve as soonas further resources commitments will become available

The physics impact of the staging and deferrals was discussed in detail with the LHCC

It has to be clearly understood that the full potential of the ATLAS detector will need to be restoredfor the high luminosity running which is expected to start only very few years after turn-on of theLHC, and to last for at least a decade

ATLAS has pursued, since the October 2002 RRB, the initial detector construction and planning within the accepted framework of the ATLAS Completion Plan, CERN-2002-114rev.

Since then many constructive interactions continue to take place with Funding Agencies, and the national communities continue the necessary actions to secure more funding in order tocomplete the detector

Step by step the overall funding situation is slowly improving, even though ATLAS is still shortby some 14 MCHF to meet its initial detector requirements, and therefore will be forced to startup with a significantly staged configuration

The present status of the Completion Funding planning is given in the updated table (CERN-RRB-2004-116)

There is also an issue of cash flow, which will be addressed in the budget discussion later on

For the implementation of the Completion Plan it is very important for the Collaboration thatthe funds for deferred items will be made available early on, documented to the RRB based on ATLAS agreements specifying in a transparent way the corresponding accounting

The Collaboration is very grateful to all the Funding Agencies that have already agreed to the category 1 completion funding and found new resources, and it hopes very much that the others will be able to support the ATLAS completion as well in the future

Conclusions

The ATLAS detector construction is proceeding within the framework of theaccepted Completion Plan

Further important milestones have been passed in the construction, pre-assembly, integration and installation of the detector components since the last RRB status report, and several outstanding

technical problems have been overcome recently

The remaining construction concerns are regularly reported to, and reviewed with, the LHCC referees

Large-scale system tests continue, and in particular the combined test beam runs, ending in two weeks, have been a very major activity in 2004

M Nessi will report on the installation in the cavern, which was impacted by the most critical component construction delay for ATLAS given by the Barrel Toroid,

but good progress can be noted there as well, on which a new schedule can be based

Very major software and computing activities are underway, with the running of DC2, which turned out to be a harder task than initially foreseen

Planning for the commissioning and the early physics phases is progressing well

ATLAS remains on track for LHC physics in 2007
