Notes XO Integration Meeting 12.08.2024, posted by Frederik Wolff-Fabris on 12 Aug 2024, 09:44
|
General Announcement:
- A power glitch happened on the weekend but had no effects on the machine. So far XO is not made aware of effects at XFEL. Please let XO know if you were affected.
CTRL:
- Nothing to report.
DA:
- Unfortunately the CAL noticed the past week that issues related to the upgrades in the maintenance period, which result in disturbances across most instruments with beam last week.
A new version of the online correction software meant to be installed then and tested during the bring-up days, but the old version ended up still running at most of them.
When bug fixes found since then were meant to be distributed in the past two weeks as we commonly do, this inadvertently also switched these to the new version, the last time on last Tuesday.
This was particularly aggravated by the fact the new version has some minor naming and UX changes, which the instruments had to adapt to now during operation.
Most issues reported through the DOC have been hot-fixed already, with more fixes prepared over the weekend. The DOC will contact instruments to apply these as needed.
EEE:
- FXE mono mitigation is in place and working.
VAC:
- Nothing to report.
XPD:
- Remarks on SA1 HIREX interlocks over the weekend has been addressed. Naresh K. is contact with XO, SPB/SFX and FXE.
DET:
- Nothing to be reported.
ITDM:
- Nothing to report.
XRO:
- Not present.
LAS:
- Working on SPB side and performance improvements were done.
UNSYS:
- Everything is fine.
SPB:
- Calibration issues as mentioned by DA. It is an operational risk for AGIPD until it is clear what happens with the calibration/errors.
FXE:
- Nothing to report apart of the Mono.
MID:
- All fine at MID. Calibration is not a big problem for MID as they do not use AGIPD.
HED:
- In contact with DOC to reset some ADCs.
SCS:
- Not present.
SQS:
- Not present.
SXP:
- Nothing to report. |
