Agenda

Action items from last meeting:

• Supergroup meetings
  • Mark Pitt to organize
  • want 2-3 meetings (every 3 weeks?) before next collaboration meeting (end of July?)
  • Simulation not a part of this group per se, but Dustin or Juliette should always attend
• Electronics at TRIUMF
  • Michael will confer with Dave to make a report to supergroup
• Simulation
  • next teleconference (May 4th, 3pm) will be about simulation structure
  • following (supposed to be May 18th, will be changed) will be a progress report on this meeting
  • simulation meetings to discuss simulation issues - physics results and/or questions could be reported at supergroup meetings

Minutes

• Supergroup Meetings
  • Organized by Mark Pitt
  • 1 per month in June, July and August, before collaboration meeting in mid-September
  • Tentative Dates and Major Topics for Supergroup Meetings
    • June, 11th or 12th - Spectrometer Update (Juliette)
    • July, after the 14th - Tracking (speaker TBA)
    • August, 23rd-31st - Detector Simulations (Peiqing and/or Jon Wexler)

• TRIUMF Project Status for MOLLER
  • Michael is in contact with TRIUMF about creating a Project Charter (first step)
    • would require "Gate Reviews"
    • treated as if it were a TRIUMF experiment
  • Spectrometer
    • engineering support for the magnets - need to know by beginning of August
  • Electronics
    • engineering support - may not be necessary
      • need detector simulations to confirm numbers from MIE appendix
      • need to revisit all the numbers with Des Ramsey and consider other "lessons learned" from Qweak (like the filter cutoff in the ADC?)
    • manufacturing support - assuming they will be very similar (identical?) to Qweak

• Simulations
  • Detector simulations
    • "PREx" benchmarking
      • setting up PREx detectors to benchmark PREx I
      • try to increase light yield -> PREx II
      • increase size of light guide -> moving to MOLLER-like detectors
    • "Qweak" benchmarking
      • simulation for main detectors which predicts exact #pe's
      • simulation for scanner detector -> MOLLER-like detectors
      • first-pass MOLLER-like simulation based on scanner simulation - 10 pe's (needs work)
  • Number of pe's depends on:
    • geometry and angle of quartz
    • geometry of light guide
    • surface properties of light guide inner surface
  • Simulation Structure
    • replication of detectors - done carefully so easy to modify, but also able to manipulate individual pieces?
    • collimators and coils should be able to be sensitive detectors (messenger command for this and secondary tracking)
    • need position, timing, energy deposited --> digitization module
    • PREx light collection code should be immortalized in the MOLLER svn repository
    • Seamus will work with UMass student to produce a document which describes detector geometry

• Future simulation meetings
  • June 15th at 3pm (needs to be set up with Stephanie)
    • Dustin will lead the teleconference
    • Topic will be a description of the scanner benchmarking and simulation progress (Peiqing)
  • Impromptu meeting during Users Group meeting (June 4-6) to discuss GDML geometry in general (Juliette to summarize?)
  • Future simulation meeting devoted to discussing the minimal set of parameters for GDML geometry description of detectors

Return to Teleconferences
Return to MOLLER at 11 GeV E09-005
