Run Coordinator report: Fall 2021 w16
From GlueXWiki
Thursday, December 2:
- Established beam last night before midnight.
- Harp scan extrapolation looks to be focused a bit differently than before. PS rates seemed around 3.2kHz as before with 150nA beam so we kept this.
- Radiation levels at 50nA acceptable.
- Continued production on C target at 150nA. Beam not available for most of Early Riser shift so far.
Friday, December 3:
- Tried re-tuning the beam yesterday (reducing MQP5C11). Resulted in lower PS rates (~2.8 kHz) consistent with what was observed previously when we tried this. See: [1],[2]
- After reverting to optics before the change, PS rates back up (~3.3 kHz). See: [3],[4]
- Hovanes performed collimator scan [5]
- Continued C production running overnight.
Saturday, December 4:
- Continued C production running. Took amorphous run yesterday evening, run 90382 [6]
- This morning had an issue with an FCAL FADC. Indication also from livetime at 5% [7], [8]. Sasha made a controlled access and swapped in a new FADC [9].
Sunday, December 5:
- Continued C production running. Pretty smooth running throughout the day and overnight.
Monday, December 6:
- Continued C production running. Smooth during day and swing.
- Alarms for TAGM1 and TAGM2 d/c from DAQ [10]. Sergey made an access to tagger hall after unable to remotely recycle the crates. Determined to be a network problem. Problem mysteriously cleared before IT on-call from off-site could arrive [11].
Tuesday, December 7:
- Continued C production running. Few accelerator disruptions (2.5h swing) but otherwise smooth for us.
- Amorphous run taken yesterday during the Day shift.
Wednesday, December 8:
