  1. Cryo
    • solenoid gobbled up another ~450l LHe
    • continue today to fill in more
  2. Comp Cal installation
    • Survey and positioning repeatability tests
    • Detector infrastructure installation
    • Detector operations tests!
    • Planed close up of hall 3-4pm?
  3. Run Plan
    • Beam into tagger hall tonight
    • Shifts start at 8am Thursday morning
    • Run Plan:
      • Week11
      • Week12
      • Week13
      • Second Energy change will take about 48 hours
      • Only Hall B and D at 5 pass: Higher beam currents for D beneficial!
      • What are nominal beam conditions?: Current, Radiator, ...

  1. Week End running
    • Lumi scan continued and completed Program
    • High lumi test done (Sasha)
    • DAQ tests done (Sergey)
    • Production data taken
    • GLUEX E12-06-102 COMPLETE! THANKS TO EVERYBODY!
  2. Reports:
  3. Plans This Week
    • installation of COMPCAL
    • solenod ramp down, off for the remainder of the year
    • Detector groups: please decide what to shut down (your call)

  • Its Black Friday!
  1. Since Wednesday
    • Start with luminosity scan (scratched transmission optimization).
    • First part complete: Amo and Diamond up to 300nA beam, Mode 9 and 10(raw)
    • Continue with data production
    • Thursday early morning, major beam down due to communication failure to RF chassis (pc104 cpu).
    • Major power glitch "Brown out", caused down on Friday early morning, and RF separator issues.
    • generally quite a rocky data taking period.
    • general data quality looks reasonable.
  2. Run Plan
    • continue production data taking nominal sequence with nominal beam current
    • high luminosity test (red program) when Sasha is available (Friday or Saturday)
    • any other requests for studies before beam goes away on Monday morning???
    • we do NOT have a low current (50nA) thinnest amo (1e-5)
  3. AOB
