  1. Last 24h:
  2. Reports
  3. Issues
    • 24 tagger channels off
  4. Plans
    • Flux optimization/Act .Col. calibration
    • Trigger development for TOF trigger
  5. Commissioning steps temporarily postponed:
    • PS and TAGH HV scans
    • Bleed-through test: measure bleed-through with A slit as usual and A slit completely closed to see whether using B slit would help.

Thursday June 16

  1. Last 24h:
    • No beam since last meeting
    • Still getting tagger voltage alarms (should we just turn those counters off?)
  2. Reports
  3. Issues
    • High trigger rate in CTOF
      • MWPC #6 window cover removed. If successful, great. Otherwise, attempt to move helium bag downstream.
  4. Plans:
  5. Upcoming Items:
    • PS and TAGH HV scans
    • Bleed-through test: measure bleed-through with A slit as usual and A slit completely closed to see whether using B slit would help.
    • Tagger Access:
      • Change HV crate (Nick, Chris)
      • Install helicity fibers and connect to DAQ
