Revision as of 09:41, 2 March 2020

Last 24 hours
- Harpscan done at 12:43pm. [1]
- Good production afternoon-7 pm
- tripy beam 7:00pm - 9:30pm: beam tripping off tagger BLM. Asked to shift 5C11B x position from -0.5 to -0.75.[2]
- No beam 11:00 pm - 7:00 am
Reports/Issues
- Gluon05 monitors
- DIRC root_spy monitoring plot
- DIRC LV regulation issue: [3] [4]
  - Conclusion: adding LV regulation to the DIRC todo list.
- Transmission issue
Run Plan
- No beam 8am-10am , Hall B beam restoration software reset.
- Production
- Starting with a special HARP scan requested by Hovanes: hall A on at 150nA, 350nA for us, use Tagger_Electron_Left_Halo for analyzing.

Last 24 hours
Beam stability
- Harp and Collimator scan (before :11:30am). Convergence Collimator scan
- Request to change collomator position by Hovanes at 4:30pm [5]
- Production till 11pm with 350nA, then 250nA
- No beam overnight
Reports/Issues
- Rate and ratios
- root_spy crashes when started on Gluon03: [6] [7]
- DIRC temperature/communication error [8]
- Monitoring issue: Low phi,rho,omega yields FCAL timing difference for run 71933 and 71934
Run Plan
- No beam 8am-10am , Hall B beam restoration software reset.
- Production

Last 24 hours
- Smooth running. 5B triggers per day. Beam trip reduction: 21 trips/hour Friday swing - 10 trips/hour owl Monday.
- AD00 study successful (contributing to 45/51 trips)
  - Report: https://logbooks.jlab.org/entry/3795114
  - Hall A bleed-through was hitting a flange
Reports/Issues
- Hole in the FCal occupancy Sunday Owl: https://logbooks.jlab.org/entry/3795081.
  - Board replaced: https://logbooks.jlab.org/entry/3795190
- root_spy crashes on gluon machines and DIRC plots aren't there.
- Monitoring issue resolved after RCDB timestamp change.
  - New sets of reference plots needed for high luminosity
  - gluonraid4 filled: https://logbooks.jlab.org/entry/3795382
  - Collimator scan: https://logbooks.jlab.org/entry/3793951
- New beam accidental scaling plot (Beni)
Run Plan
- Production
- Harp scan
- Beam study tomorrow 9-5pm.
