1.3 Monte Carlo

  • MC Noise - CH
    • Look at large cpu load

1.4 Pattern Recognition - AD

  • Find a way increasing error for low pt tracks and implement Progress made, confidence factor added to pat rec tracks data structure, not yet populated

1.5 Online Displays - MU

1.6 Performance

  • Spacepoint efficiency study - CH, AD

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?
  • DA to give his requirements for the Hall and the tracker lab, in particular with respect to the Integration Schedule (MU to email)
    DA coming to U.K. in first two weeks of September

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

2.1 MiniDAQ - DA

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

2.3 Controls

  • Create controls system - DA

2.4 Hall Probes - MU

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

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

5. Installation

  • ISIS long shut down: 25th Aug 2014 - 8th Feb 2015
  • Possible helium leak on the downstream solenoid
  • Expecting to move downstream SS to Hall on Monday
  • 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
  • Northside PRY (not us, but knock effect to us)
  • Not yet able to test against multiple tracks per trigger with MC

9. AoB and summary of actions.
