Agenda and Minutes¶

0. Actions¶

• Create MICE note of channel mappings end-to-end through hardware, electronics and software - DA
  • Find D0 note and make into MICE note - AB Done, MICE note 447

1. Software: AD, ES, CH¶

• Schedule - AD See MAUS Schedule.

1.1 Documentation - AD, ES, CH¶

1.2 Geometry, Calibrations, Configurations, CDB - CH¶

• Clean up - CH
• Helium windows not in geometry - CH Done in MAUS trunk

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
• Does low pt performance need improving?

1.5 Online Displays - MU¶

• Schedule now to be finished before next CM
• ACTION: Add check on RF window position somehow e.g. trigger requests vs triggers accepted (request from E0) - MU
• ACTION: DA to communicate modifications to list to MU - DA, MU

1.6 Performance and Analysis¶

• Emittance error - discrepancy by C. Hunt results and ES results (ES ~0.6%, CH ~ 0.8 - 1.5%)
• Bias difference between trackers to be investigate - C. Hunt, ES
• Spacepoint efficiency study - CH, AD
• Low pt performance - AD
• Efficiency and Purity figures for different beams and geometries

1.7 Issues¶

• Final track fit - ES
  • Deal with -ve charge
• Possible bug found in plane mapping
• Cosmic data not reconstructing - AD pursuing
  • See MAUS issue at http://micewww.pp.rl.ac.uk/issues/1467
  • Current repair effort code branch at https://code.launchpad.net/~phuccj/maus/cosmic_repair

1.8 Tracker Software Paper¶

• Latest draft: MICETrackerSoftware.pdf
• P. Kyberd agreed to serve as editor
• Waiting on results for emittance measurement performance

2. DAQ/Calibration/Controls - DA, EO¶

• Tracker DAQ / electronics QA: See DA talk AFE-QA_141001.pdf
  • Second DAQ / electronics test in Nov 14?
• Plan for integration with beam: doc
• Vacuum pumps repair - CMacW Thought to be not needed after expert inspection

2.1 MiniDAQ - DA¶

Being used.

2.2 Channel Mappings¶

• Create comparison plots for channel mapping data if needed - CH
• 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.

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 EO submitted and back
• Finished second pulser box - CM
• Polish fibre ends - CM
• Make documentation mapping LEDs to areas of tracker illuminated - EO
• Provide documentation 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 finished writing and check everything in more detail.

4. Tracker lab - AB, GB, CM¶

• Set up cryostat test system - CM
• 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
• Finish installation manual - GB, MU Done, stick final version on wiki

• Schedule
  • Current schedule at Integration Schedule - timetable still subject to change (constraints from AFC, etc)
  • Add resource loading? - CM

• 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.

• Want cryostats in hall and cold by Monday 17th Nov 14 - CM, AB, DA
  • Do we want to keep the cryostats cold afterwards?

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)
• Power supply
• Not yet able to test against multiple tracks per trigger with MC

9. AoB and summary of actions.¶

9.1 AoB¶

• Deadtime in the tracker - is it an issue?

9.2 Actions¶

• Create MICE note of channel mappings end-to-end through hardware, electronics and software - DA
• Add check on RF window position somehow e.g. trigger requests vs triggers accepted (request from E0) - MU
• DA to communicate modifications to list to MU - DA, MU
• E0 to email S. Boyd about potential deadtime issues
