Minutes
Hall
- 3 pass (~2.5 GeV) until Thursday
- 5 pass for remainder of time after Thursday
FCAL
- data taken at 5% of 2.5 GeV
BCAL
- found clog in quick disconnect (Elton, Alex, Yi, John) temps dropped by few degrees C, still +3 C on downstream side, differential between chiller and downstream decreased to 1 C
- swapped flow direction from down to up to up to down (Elton, John) and downstream stayed +3C, confirming hypothesis of poor thermal connection on downstream side
- Elton will give thorough report on thermal glue used at next meeting
- data taken at different bias voltages
- still see oscillations
Future plans
- look at scalars today(FCAL)
- look at different DAQ modes tomorrow (FCAL)
- will take data at different thresholds this week (BCAL)
- install CTP in a few weeks to look at trigger options
- all detectors will remain in current location until 5 pass beam is restored
