Thursday, January 16 at 08:45
- Last 24 hours
- Trippy beam yesterday and overnight. Issues in two cryomodules.
- Some production data was collected.
- L1 triggers studies have been postponed to today.
- Issues
- Major bleed through, presumably from Hall A 1-pass beam 3764868
- Tasks for today
- After spin dance (11 am -3 pm in accelerator plan): L1 triggers studies (Sasha, Beni, Justin)
- Followed by cDAQ test (Sergey)
- Production data otherwise
- Plan for later
- Tagger accidental study (Richard). Tomorrow early a.m.? Will contact RadCon for final ok. Richard's proposal
- Empty target run (target will already be emptied for accidental study).
- Discussion of 24 GeV physics came up, physics ideas are welcome.
Friday, January 17 at 08:45
- Last 24 hours
- High rate scan [1]
- cDAQ
- TOF thresholds
- Issues
- Tasks for today
- Production data taking
- RF recovery starting at 9 am
- Accidental study (Richard), 1 pm. 2100 nA beam, most HVs will be turned off, empty target. RadCon will monitor. Richard's proposal
- Empty target run (2 hr)
- 30 min runs at 250 and 350 nA? To check number of rho, omegas / trigger. All subsystems ready?
- Plan for later
- Happy three day weekend! 🙂 Production data. No studies or downtime planned until Tuesday.
- Next meeting: Tuesday
Tuesday, January 21 at 08:45
- Since Friday meeting
- Accidental study: success up to 2100 nA!
- Empty target run
- Production data over weekend: increase to 250 nA
- Upload of most recent f250 firmware to PS, TAGH, TAGM. Timing changed afterwards, monitoring plots affected, updated calibrations to test. PS rates also affected.
- Issues
- Monday am: Hall D tagger went to restricted access?
- Monday am: 5H00 vacuum fault
- Monday pm: solenoid dump. Scott brought back to OK state, cause unclear.
- Tasks for today
- Hall open until 1 pm.
- Controlled access: solenoid investigations, FCAL base replacements, DIRC experts. Any others?
- Hall open until 1 pm.
- Plan for later
- Production, when we can!

- Issues
- Tasks for today
