Minutes

AI and CDC HV Test, Naomi

  • Use AI to stabilize chamber gain
  • Employ more variables than just atmospheric pressure, e.g., beam flux
  • Expect changes of ±20 V
  • Changes only at the start of run
  • Changes must be approved by shift person
  • In addition to dE/dx, time-to-distance relationship can change with pressure
  • Will come back at a future meeting to give more complete exposition
  • Preview her slides here.

File:Simple Comparisons between Richard and Rory.pdf

BH Generator Comparisons, Andrew

  • Compares Richard's generator to Rory's. See his slides here.
  • Generally good agreement, differences in the details.
  • Asymmetry in azimuthal distribution between 0-π vs. π-2π visible in Richard's model, similar to data.

Plugin for π/μ studies with muon chambers, Andrew

  • Working on it, will pass data to David L. and Kishan.

Chamber Testing at JLab, Alex

  • Taking data for a week now, 40 million events collect thus far
  • Albert will be analyzing data
  • Andrew has passed system for decoding EVIO chamber data from David L. from 2015 on to Albert

Cable shielding sleeve grounding, Alex

  • Asked about plan for grounding of chambers at JLab
  • In advance of coming to JLab next week, Andrew will ask Rory about the scheme. He may be doing the job himself when he arrives.

Next Meeting Time, All

We agreed to meet in a week at 10 am again.
