- In last 24 hours:
- FDC chiller tripped due to overheating - no chilled water flow: https://logbooks.jlab.org/entry/3923962
- Could not do rapid access - beacon bulb burned out - https://logbooks.jlab.org/entry/3924326 (lost about 40 min)
- Early riser summary: https://logbooks.jlab.org/entry/3924292
- Owl summary: https://logbooks.jlab.org/entry/3923921
- Swing summary: https://logbooks.jlab.org/entry/3923728
- Day summary: https://logbooks.jlab.org/entry/3923480
- ~400M triggers with B-field LHe 200nA + 300M without FDC
- short downtime (~30 min) HallA BLA calibration
- Run 81504 in raw mode
- Run 81505 ~40min no D laser, B,C up, A down, last minute with the D laser.
- PS background https://logbooks.jlab.org/entry/3923621 (Sasha)
- spike in beam current https://logbooks.jlab.org/entry/3923798
- Remaining issues:
- fixed the beacon and the FDC chiller
- noisy FDC wires https://logbooks.jlab.org/entry/3923747
- Bleedthrough
- Plan:
- 2 more shifts with 200 nA and target filled with He then wait for decision from Primex 4 pm meeting.
Friday, October 15
- In last 24 hours:
- power of infiniband switch tripped (one strip cord)- causing 4h UED -https://logbooks.jlab.org/entry/3924903 https://logbooks.jlab.org/entry/3925176
- group disk not mounted https://logbooks.jlab.org/entry/3925185
- trigger rate not archived https://logbooks.jlab.org/entry/3925225
- FDC chiller replaced https://logbooks.jlab.org/entry/3924510
- beacon bulb replaced - took 2h
- FDC hot wires https://logbooks.jlab.org/entry/3924538 - no more noise but higher discr. thresholds (need 30 min to optimize the thresholds)
- 6h downtime - NL cold box + other things
- harp scans - https://logbooks.jlab.org/entry/3924829 https://logbooks.jlab.org/entry/3924830 https://logbooks.jlab.org/entry/3924845 https://logbooks.jlab.org/entry/3924851
- ~400M triggers for the last 24h
- pulser left at 2kHz after the downtime https://logbooks.jlab.org/entry/3924927 - all data after that till 23:30 with 2kHz pulser - don't forget to restore pulser to 100Hz once you are done with your test
- more rootspy nodes https://logbooks.jlab.org/entry/3924610 (David)
- power of infiniband switch tripped (one strip cord)- causing 4h UED -https://logbooks.jlab.org/entry/3924903 https://logbooks.jlab.org/entry/3925176
- Remaining issues:
- fix remaining problems on gluon machines
- Bleedthrough
- Plan:
- run till 5pm with full target, then with empty over the weekend - inform target group (Chris) when emptying/filling the target
- pass change on Monday
- day/swing on Wednesday - maintenance
