  6. ERR Committee submitted comments to our response. (See ERR wiki page). The concerns included
    1. MWPC efficiency and impact on physics. We had quite a bit on discussion on this topic
      • David: Chambers are not primarily for tracking as for identification of hadronic showers vs single tracks
      • Slides from Rory
      • Rory: Events are collected using the TOF trigger. Within the sample events collected are pions and muons. The MWPCs are used as a handle to classify these events
      • Rory showed some slides nicely illustrating this point.
      • Mark: Use of MWPCs is for identifying muon background and also for normalization
      • Mark: Could also use the distinct angular distribution of muon production to separate out (statistically) any residual mis-identified muons from the pion sample.
    2. Check on status of the schedule we submitted.
      • Elton produced added a status to the schedule we submitted showing that we are on schedule. Mark suggested some changes to the text to clarify progress.
      • CPP-NPP Schedule Status 5/11/2021. The following two references show that the new hdgeant4 simulation is operational and working: Posted to the ERR wiki
      • Log Entry 3876633 Histogram of muon hits from hdgeant4 simulation.
      • Tracking / extrapolation to MWPCs Preliminary studies of extrapolation of FDC tracks to MWPCs
  7. hdgeant4 simulation
    • Elton, with Mark and Beni's help, has been able to generate samples of muons in the target and illuminating the MWPCs.
    • We can improve a) drift time b) pulse height distribution c) deadened region. The most important for simulations is the deadened region, as we do not have specific uses for time/pulse height
    • Simon "volunteered" to implement the deadened region around the beam (10 x 10 cm2).
  8. Shipping of MWPCs
    • Rory has checked his calendar and driving the first set of 4 chambers down to JLab is proposed for the week of June 7.
    • He plans to drive the MWPCs down to JLab and fly back. Unloading will require Hall D technical staff. That will give us time for setup for testing.
