Run Coordinator report: Spring 2018 r7

• Accomplishments
  • Production running (1350 A, thick diamond); Feb 21-28: 12.4 billion triggers // Total to date: 63.5 billion (67% of goal)
  • Muon MWPC studies carried out (radiator and noise)
  • nA BPM work by John Musson et al advanced significantly
• BANU Picture
  • Solenoid dump (~5.5 hours)
  • Active Collimator failure (~7 hours)
  • Tagger Fake Fire Alarm (50 min)
  • Tagger Dipole trip (20 min)
  • DAQ issues (1-2 hrs)
  • Goniometer restart (30 min)
  • Routine polarization changes (~80 min per day total)
• Issues
  • Accelerator: 5C11 beam oscillations. Still assessing effects on our detectors
  • Hall D
    • Active Collimator failure; Beam Profiler used for about a day; AC repaired
    • Routine FCAL base repair/replacement during opportunistic access
    • Solenoid dump (5hrs beam loss) due to PLC communications & PXI chassis: ramp up partly during RF recovery; time mitigated by advancing our thin diamond scan
• Plans Ahead
  • Production, 1350 A solenoid, thick diamond (58 μm) to ~95 billion triggers
  • Routine daily HARP scans; feedback to MCC on beam focusing
  • Swing shift today: luminosity scan 90-300 nA on different radiators.
  • nA BPM tests: Beam Profiler, low current, check rates. J.Musson: Mar 1 or 2?
  • Thin diamond (17 μm) runs on Mar 7
  • Empty target runs (once every 2 weeks) - next one on Feb 28
  • TAC runs/tests on Mar 9
  • Fast raster beam characterization on Mar 9
