Integrated trigger count

Tuesday, August 11

  1. Last 24 hours
    • 11:45am: 5th pass separator cable melting [1], [2]
    • 7:45pm: beam returned, continued production running
    • 4:00am: 5th pass separator trip, crew chief gives Hall D priority with magnetic separation
    • 6:00am: separator repaired, switch back to RF separation
  2. Reports/Issues
  3. Run plan
    • Maintenance day (>4h):
      • Intervention on TagM (Richard, Nick, Chris)
      • Installation of test crystals (Sasha)
      • Work on GEM TRD (Lubomir)
      • FCal base replacements (Mark)
    • Tune beam spot on diamond for 45/135 (Hovanes)?

Monday, August 10

  1. Last 72 hours
    • Beam returned Saturday 4am
    • Harp scan, initially problems with GUI settings
    • DAQ/HOSS problems: [4], [5] (Saturday morning)
    • Start of 350nA production cycle on Saturday day shift, but beam tuning to A ongoing [6]
    • Saturday swing: AC bias testing, [7], status
    • MCC confused about FSD trip and goniometer movements: [8]
    • Sunday 1pm: Cryoleak in 1L20, tripped pump, beam restored at 10pm
    • Harp scan: [9], [10], [11]
    • Completed first full cycle of 4 orientations + amorphous
    • DAQ problems on Monday morning: [12], [13], log files from moving to tape fill up disk, Sergey will work on a system to prevent this
  2. Reports/Issues
  3. Run Plan
    • Continue production
    • Maintenance day on Tuesday:
      • Intervention on TagM (Richard, Chris)
      • Installation of test crystals (Sasha)
      • Work on GEM TRD (Lubomir)

Friday, August 7

  1. Last 24 hours
    • Diamond alignment check (Hovanes)
      • Coherent edges are reproducible to about 20 MeV, tweaking may be necessary
      • Add screen shots of the coherent edges to logbook
      • "force para" or "force perp", as appropriate, and "save as default" for each of the four settings
    • Trigger check-out (Sasha)
    • TagH and PS HV scan, interrupted by pass change
    • Storm, optics tuning, several issues, transformer repair
    • No beam since, expected only this afternoon
  2. Reports/Issues
  3. Run Plan
    • Access?
    • Harp Scan
    • Complete first production cycle with 350nA

Thursday, August 6

  1. Last 24 hours
    • 5th pass separator problems after thunderstorm in the evening
    • Beam recovered around midnight
    • Harp scan: results
    • Radiation levels checked: similar to spring
  2. Reports/Issues
  3. Run Plan
    • Diamond alignment (Hovanes)
    • Trigger, PS, TagH check (Sasha)
    • Pass change at noon
