Use BPM ? Use Tracker ? Upgrade TOF discriminators ?

Controls And Controls And MonitoringMonitoring

Good progress on all frontsGood progress on all fronts Groundwork required to unify MICE control systems &

create a user-friendly interface is well underway

Controls effort is ‘significantly understaffed’ Controls effort is ‘significantly understaffed’ (DAQ & Controls Review, June ‘09)(DAQ & Controls Review, June ‘09)

We are always operating at full capacityWe are always operating at full capacity ‘‘Controls & Monitoring’ is such a broad Controls & Monitoring’ is such a broad

subject that many unexpected additional subject that many unexpected additional requirements crop up all the time…requirements crop up all the time…

See James’ Talk for details


Application Launcher

• New application launcher replaces DL TCL script

– XML configuration file, easy to add items

– Unlimited subcategory levels

• Provides real-time display of application status

• Configurable response to existing application instances


Target: Controller

• Target Controller Stage 1 upgrade underway

– Hardware essentially complete

– Currently working on Controller firmware (P. Smith)

• Software nearing completion– Hardware driver framework in

place

– Have implemented all EPICS server / client functionality

• Tested using ‘virtual’ Target Controller Device

– Remaining task: write low-level hardware driver plug-in once firmware is complete

Stage 1 upgrade - Control functionality includes:

- Set delays- Set / monitor Target depth

- Park / hold, start / stop actuation- Monitor hardware status


Target: Beam Loss• Standalone DAQ system upgrades:

– Final algorithm selected for ‘absolute’ beam loss calculation

• Thanks to AD for implementation

– Standalone event viewer can now follow real-time output of DAQ

• Target Beam Loss IOC will read local data archive written by DAQ & serve values as PVs

– Enables integration with Alarm Handler & readout of actuation numbers for CDB run data entries

– IOC will use same analysis & file access code as standalone DAQ, via C wrapper functions

– See PH’s talk

ConfigurationConfiguration Data BaseData Base Doesn’t Store Data Doesn’t Archive the parameter read values Store the Geometry, Calibration Constants, Set

values, etc

Use Case example: Use Case example: Give me the configuration of the experiment at

16:15 on 5th November 2009 Needed by reconstruction software to analyse the

data

Relational AND bi-temporal. Relational AND bi-temporal. Please see previous collaboration meeting talks

for a fuller explanation of this concept and its justification.


Database Functionality 2

Since the last collaboration meeting there has been much progress Geometry

- Can now write and read geometries- We can reconstruct what the geometry was known to be for a given time. We have a history of state.We also can update when misalignments are found. We have a history of those updates. You can reconstruct what was KNOWN about the state of the geometry at some set of given times, very easily.

Calibration- Can now write and read calibrations of arbitrary format- One default calibration should be maintained by the detector groups but others can be kept and called specifically

Set Values- Can now write and read set values - EPICS GUI (James Leaver) interfaces with this. Thanks also to Pierrick & Adam for help with cataloguing many set vals.


Configuration Database: User Entry• Not all parameters required for a CDB

‘run’ entry are available through normal EPICS channels

– i.e. Relevant IOCs & integration with the DAQ are not yet complete

– Currently only beamline magnet currents can be backed up from ‘live’ servers

• (Quasi) temporary solution:

– Generic EPICS data server hosts PVs for all values missing from existing IOCs, so they can be read by backup/restore client

– User entry client allows shifter to enter required parameters before initiating a run

– As future work progresses, unnecessary user entry items will be removed

• However, shall always require some degree of manual data entry

Summary

Database is progressing wellWish to finish database functionality and

perform stress tests which could be presented at CM26

Nevertheless, people should think about integrating DB communication with their applications (contact me for info – [email protected] but this is an action item for others)
