RC summary, 08/27/2020 - 09/02/2020, Igal Jaegle
During the first 4 days, we were in data production more, and the last 3 days were devoted to CPP tests & DIRC commissioning. The downtime due to us was large: 38.8hr
- 12hr hall access for installing the CPP test
- 14hr hall access for de-installing the CPP test and installing TRD-GEM
- 12.8hr invasive hall access for detector (DIRC) repair, active collimator scan, changing radiator, and starting runs
The most notable issues were
- CDC & FDC HV did trip without any alarms resulting in the loss of 3 data production runs
- DIRC problems (South Box Group 9 LV) which required invasive hall access
- Solenoid did not ramp down and up as expected delaying the TRD-GEM installation by 5 hours
- Beam down due to weather + communication wrath during 18hr
Apart from that, in total 18B "good" physics trigger were taken.
