Monday, February 3
- Last 72 hours
- Friday:
- No beam 10am-12pm (BLA calibration). Opportunistic Hall access.
- No beam 3pm-4pm (MCC software update).
- No beam 4pm-11pm (lost vacuum in Hall C transport [21]).
- Saturday:
- Goniometer stopped moving sometime between 5am and 3pm. The problem was only noticed at 3pm [22]. As a result, a few runs have unknown diamond orientation [23],[24]
- Repair work on goniometer from 4pm till 7:30pm (no beam) [25]
- At 10pm, lost HV on TAGH 121-127 and beam halo. HV crate T8-1-BOT has died and wouldn't boot. Repairs were postponed until next morning [26], [27]
- Sunday:
- Production
- In all the chaos over weekend, we managed to collect 7.9B triggers. However, 1.9B events have an unknown diamond orientation, and 1.7B tirggers have beam energy hole.
- Friday:
- Changes
- Issues
- TAGM is "immobilized" to keep goniometer moving.
- TPOL slot 13 channel 3 is always saturated [35]
- Remote reset cable for T8-1-BOT needs to be repaired.[36]
- FDC HV channel 2:c4:4p was in constant trip loop and was set to lower HV [37], [38]
- TOF T:45 20V difference between HV setpoint and readback.
- Gluon05 needs to be rebooted almost daily.
- As ususal, new DIRC holes require DAQ reboots.
- Do we need a dumplette inserted for all goniometer movements? [39]
- Noteworthy
- MCC sees our radiator IN & OUT at the same time [40]
- Reports
- Plans for today
