Monday, September 5

Labor Day Holiday Special (9.30am, note one-off different time)

Weekend Run Updates

Issues from the weekend

  • Return of the ST gap
  • Out of date list of subsystem experts, some updates applied in the wiki
  • [1], [2] Overnight FCAL issue caused by voltage changes.
  • Changes to subsystem settings and configurations should be recorded in a separate logbook entry at the time they are applied. This helps shift crews to pin down the cause of any unexpected effects before calling the RC with a generic "there's somethng wrong".
  • Remote connection to counting room, remote shift takers should CHECK THEIR CONNECTION WELL IN ADVANCE OF THEIR FIRST SHIFT
  • Timekeeping, in person shift takers SHOULD ARRIVE IN TIME FOR THE START OF SHIFT, not 5-45 minutes after

Plan

Sunday, September 4

Saturday, September 3

Friday, September 2

Past 24 hours

Issues

  • Shift crew just reported that Ar and CO2 cylinders are low
  • DAQ issues late night
  • Hydra very slow updating last night (>10,000 seconds)

Plan

  • Intensity scan; 3 shifts each at 50nA and 100 nA, 12 shifts at 200 nA (almost 6 completed)
  • Trigger Studies
  • Access needed to restore target comms
  • Solenoid ramp down Monday, zero field runs Tuesday
  • Target change intended for Wednesday

Thursday, September 1

Past 24 hours

Issues

Plan

  • Brief accelerator downtime around 1pm for preventative maintenance on a UPS in the injector
  • Trigger study (Sasha)
  • Detector checkout (raw mode for ADCs & pi0 for FCAL)
  • Intensity scan?
  • Physics production
    • Take data with B-field (six shifts at 200 nA, then two each at 100 nA and 50 nA)

Further Information
