Agenda and Minutes¶

0. Actions¶

• Asymmetric results between trackers: Kalman to extrapolate back to tracker reference surface - C. Hunt, ES
• Create MICE note of channel mappings end-to-end through hardware, electronics and software - DA
  • Email AD about mappings - DA
  • Find D0 note and make into MICE note - AB
• Create comparison plots for channel mapping data - CH

1. Software: AD, ES, CH, ST¶

• Schedule - AD See MAUS Schedule.
• MAUS version 0.9.0 released with lots of scifi updates

No update

1.1 Documentation - AD, ES, CH¶

• Base documentation - AD
• Digitisation - CH, ES
• Pattern Recognition - AD
• Track fit - ES
• MC - CH
• Geometry, CDB - CH
• Noise - CH

No update

1.2 Geometry, Calibrations, Configurations, CDB - CH¶

• Helium windows not in geometry - CH
• Get CMM geometry data in to CDB - CH
• Translate CDB geometry xml into MiceModules format Now able to pull down from CDB but still crashing when try to run sim with it - AD, C. Heidt

1.3 Monte Carlo¶

• MC Noise - CH
  • Look at large cpu load
• ADC smearing needs fixing - CH

1.4 Pattern Recognition - AD¶

• Find a way increasing error for low pt tracks and implement

1.5 Online Displays - MU¶

1.6 Performance¶

• Spacepoint efficiency study - CH, AD
• Bias difference between trackers to be investigate - C. Hunt, ES 99% solved, need to get Kalman to extrapolate back to tracker reference surface
• Low pt performance - AD
• Recon emittance vs MC truth emittance study - C. Hunt
• Spacepoint efficiency study - C. Hunt

1.7 Issues¶

• Final track fit - ES
  • Deal with -ve charge
• Possible bug found in plane mapping

2. DAQ/Calibration/Controls - DA, EO¶

• DAQ system test in Nov 14?

  Plan for QA in September doc
  Plan for integration with beam doc

One of the cryos has been cabled up so we have one board readout electronics all cabled up. No problems yet. Running, initialises and reads out compressed data Pedestal data taken (as cryos not cold) 1 run taken with bayonet out and one in (shows load above pedestal) visible in ADC distribution. Boards show no major problems with chips etc. Rest of boards will now be checked. All checks that can be done while warm will be done. VLSB and cables all cycled through.

Vacuum pumps brand new but all broken. Will be serviced by Craig in due course.

2.1 MiniDAQ - DA¶

Being used.

2.2 Channel Mappings¶

• Check our channel mapping from end to end and make sure correct - DA, AD, ES, CH
• Dig up the old documentation for the electronics channel mapping - DA
  • AFE/cassette channel mapping: MICE note 447.

came from concerns that channels were swapped after cosmics. We think that it is not a problem.

ACTION: David A. to email Adam.
ACTION; AB Find D0 note and make into MICE note.

2.3 Controls¶

• Create controls system - DA

2.4 Hall Probes - MU¶

We already have a working system but we will improve it and make it more user friendly.

3. LED: EO¶

• EO currently busy with thesis, back on LED in Sept - Oct
• Finished second pulser box - CM
• Polish fibre ends - CM
• Make documentation mapping LEDs to areas of tracker illuminated - EO
• Provide documnetation to Maurizio about whether it would be helpful to fit LED into TOF to help our timing - EO

Craig has the bare bones of the system and Ed will assemble the spares when he has finshed writing and check everything in more detail.

4. Tracker lab - AB, GB, CM¶

• Set up cryostat test system - CM
• Turbo overhaul?
• Helium line in from R9 now in lab and working well

Tidy and in use.

5. Installation¶

• ISIS long shut down: 25th Aug 2014 - 8th Feb 2015
• Tracker 2 log to be produced by GB with updated numbering
• Schedule
  • Current schedule at Integration Schedule - timetable still subject to change (constraints from AFC, etc)
  • Add resource loading? - CM
• Finish installation manual - GB, MU Done, stick final version on wiki
• External waveguides
  • September to be begin QA

• Load of fibre and 5 complete connectors random received from AB, not too sure what to do with them. GB to email AB about what is available to determine if we need to order items in.

6. Services in the MICE hall: CM¶

• CM discussing with AN and JG about chilled water and compressors
• Helium lines

7. Step IV Analysis Readiness - MU¶

• Tracker alignment - MU

8. Risks¶

• Daresbury electronics: vacuum, tracker interlocks
• Reforming external waveguides (could lead to breakage)
• Leak from cryostat cassettes
  3/4 tested and tight. AB to test the 4th on 3rd sept.
• Northside PRY (not us, but knock effect to us)
  Can we add cryostats etc early..? decision to be made.
• Not yet able to test against multiple tracks per trigger with MC

9. AoB and summary of actions.¶
