- Past 24 hours:
- Acceptable quality beam established early morning around 11:00 am.
- Beam profile and convergence by Jay:https://logbooks.jlab.org/entry/3652506
- DIRC data taking.
- DIRC analysis is on-going.
- Acceptable quality beam established early morning around 11:00 am.
- Issues
- Cryo Water Temperature jump to 72F (limit 70F).
- Due to pump switch: https://logbooks.jlab.org/entry/3652512
- IOC lost communication
- IOCHDCOL failed at 21:30. Reported to us by MCC at 0:00. Reset at 1:50 am. Hovanes verified things are ok at 3am. https://logbooks.jlab.org/entry/3652920
- DIRC SSP problem:
- DAQ stopped twice due to the out of sync issue.
- Tagger RF time: https://logbooks.jlab.org/entry/3652533
- hdview2 is work working
- Cryo Water Temperature jump to 72F (limit 70F).
- Today:
- No planned access
- Opportunistic access requested by Kenoe to work on GEM.
- DIRC nominal running (MOROC threshold scan?)
Friday, Feb. 15 at 08:45
- Past 24 hours:
- Nominal DIRC setting collected 1B triggers
- Switched to the higher MOROC threshold (200)
- Smooth overnight running at 180nA, coming back to the desired 225nA this morning.
- Both opportunistic accesses happened during the accelerator down time due to the bulk power supply failure.
- Nominal DIRC setting collected 1B triggers
- Issues:
- Beam steered to the wrong BCM, therefore constrained the maximum beam delivered to 180nA
- Detailed log: https://logbooks.jlab.org/entry/3653554
- Goni camera, wrong angle, did something move? https://logbooks.jlab.org/entry/3653437
- root spy crash: https://logbooks.jlab.org/entry/3653678
- DIRC SSP
- Runs at MOROC threshold of 50 not possible due to the out of sync issue, need to be looked into
- Out of sync over night (after switching the MOROC threshold).
- hdview2 and monitoring email working?
- Beam steered to the wrong BCM, therefore constrained the maximum beam delivered to 180nA
- Plan for today:
- keep collecting higher MOROC threshold data (up to 1B triggers).
- When beam is not available, 15 min LED runs with different pulsing and trigger conditions.
- No planned and opportunistic access
Wednesday, Feb. 18 at 08:45
- Over the weekend summary:
- Quote by Eugine: "All the problems landed on other ppl's court".
- DIRC SSP firmware on Friday (thanks to Ben and Sasha)
- Low intensity program completed.
- HV scan: two more settings remains
- HI test on Sunday: for most of the day, we were the only hall up.
- ToF inner layer off, DC HV reduced, Tpol excluded from the trigger.
- DIRC and DAQ passed the test!
- Overnight: smooth 425nA scanning operation.
- Monitoring
- Plan for today:
- Hall A, B and C are down, another HI test? @900nA?
- Issues:
- hdview2: hang on the 1st event
- DAQ: Randy factor cant be set and BCALroc.
- Any update on the RF issue?
- Transition to the CPP
