Shift Summaries

Reports

Issues

  • Parsing issue with rocBCAL7 (rocID=37 and slot=16), recovered by power cycling rocbcal7
  • TAGM column 16, fadc250 stopped counting in middle of run around noon, run ended, recovered by power cycling roctagm1
  • Problem writing raw data to tape resolved, transfer to tape resumed
  • Issue writing to local disk blocked DAQ during 121161, resolved by Sergey and running resumed
  • Lockup of fcal bases continues regularly, resolved by reset procedure at the end of run (or sometimes on its own!)
  • Problems with radiator harp scans happened again, resolved by Hovanes restarting IOC, https://logbooks.jlab.org/entry/4150880 working again at 9:45pm]
  • Coherent edge (blue points) on CBREM gui spectrum not updating, work-around by bringing up separate fit tool

Plans

  • Another high current run at 900 nA during the day today?
  • Continue running production
  • Straight-track run ~50nA
    • planned for March 19th Sunday swing
    • magnetic field ramped down
    • access not required
    • people to contact: Justin, Sasha, Lubomir, Naomi
  • After beam goes away, one shift of BCAL LED data requsted -- Mark Dalton, Varun

Plans on Accelerator Side

  • Hall C running continues, no apparent issues that might interrupt them before Monday

Regular Production Cycle

  • Production (300 nA, 2h runs) with cycle:
    • 2 runs PARA (0/90)
    • 3 runs PERP (0/90) (one additional run per cycle for next 2 cycles, to catch up with PARA 0/90 -RTJ)
    • 2 runs PARA (45/135)
    • 2 runs PERP (45/135)
    • 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)
