<- Back to Run Coordination Meetings:Fall2017 Spring2018 Run
Thursday, January 25
- Notes from the previous 24 hrs:
- Beam was off from 9am till 5:20 pm. At the end, Hall A was able to get their 22.5 uA current. Since then, beam was relatively stable.
- Upon return of the beam, a harp scan was performed: MCC and Our harp. Beam seems to be acceptable.
- After harp scan, about an hour has been spent on trigger and DAQ studies by Sasha and Sergei.
- We switched to production running at 7pm and has been taking production data since then.
- ABU 10.5 hrs (0.7+3.5+6.3), BANU 0.8 hrs (0+0.3+0.5) for the last 3 shifts
- About xxxN triggers collected. Total: Spreadsheet: number of triggers
- Issues:
- A couple of hours of beam time has been lost on fighting with DAQ while starting the next run (java out of memory, rebooting rocks, etc.)
- Sometime, a histogram or two would disappear in rootspy and reappear after monitoring restart.
- Once, a coherent edge had to be nudged by more than 50 MeV.
- BCAL ADC/TDC timing offsets jumped by 32 ns for some modules: [1]
- Low level monitoring
- Any other issues?
- Short term run plan:
- TAC run: should we do it today (Halls A and C are down)?
- 2 hours of AMO 300nA running tomorrow morning.
- Would it be better to start it at 7am or 8am?
- Are any configuration changes necessary (HV, etc.)?
- Who needs to be here for such run?
- RADCON will follow this run with their Fast access study.
- Consequent Hall restricted access to fix TPOL noise issue.
- Simultaneous tagger hall access to fix bad TAGH channels.
- Possible Saturday morning access as well.
- Run plan chart: Week 3
