Zoom Connect Meeting ID: 160 199 0060 / Passcode 8394 MCC Whiteboard Hall D counting room white board Spreadsheet with list of runs Integrated Trigger Count Hall D Logbook

Monday March 20

Past 72 hours

Shift Summaries

Reports

Issues

Plans

  • straight track running plan -- completed
  • BCAL LED calibration data collection -- underway
  • cosmic data collection -- after BCAL LED runs plan completed

Friday March 17

Past 24 hours

  • Dropped to RESTRICTED for tours at 3:45pm 3/16
    • Temperature in the hall rose to >77 degrees, recovered in time
    • Visits ended by 7:00pm
    • Hall D swept and requested beam restoration
    • Started off with new harp scans, then continued production
  • Beam accounting point of interest: tour down was counted as BANU

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)

Thursday March 16

Past 24 hours

  • Tagger Hall Access requested by Hovanes
    • came as a surprise to RADCON and MCC crew
    • discussion during the 8:00 meeting
    • we can do better
  • High current run(900 nA)
    • initially blocked by Crew Chief -- discussed at 8:00 meeting
    • eventually granted after some delay
    • main participants Justin, Sasha, Lubomir, Naomi
    • trigger conditions eventually found that allow running at 75kHz data rate @ 900nA [3][4]

Shift Summaries

Reports

Issues

Plans

  • Continue running production
  • Visitors tour of Hall D starts at 4:45pm 3/16
    • Data collection should end sometime after 4:00pm, when convenient before 4:20
    • Contact MCC and ask to drop Hall D to RESTRICTED, tagger hall not affected
    • Ask them to contact RADCON to sweep Hall D for the visit
    • Visit should end by 6:45pm
    • As soon as they leave, put Hall D back in Power Permit and request beam restoration
    • Start off with new harp scans, then continue 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
