General Announcement:
- There was another power glitch last night. It seems that accelerator was not affected. If XFEL groups find affected devices, please contact XO.
- From healthy task force the Covid-19 measures stay in place as they are.
CTRL:
- Nothing major to report.
DA:
- Nothing to report.
EEE:
- Nothing to report.
VAC:
- Nothing to report.
XPD:
- Running at SA3 at the edge of the energy range (3keV is at limit of the undulator tables (K near 4)). Sara C. says that with higher electron beam energy this won't be a problem.
In addition, the problem was with only few cells and Suren A. is in contact with BKR. Jan G. says that will get in touch with Suren A.
- HED reported problems with beam pointing being instable. XPD and XRO will take a look on it and include XO for the analysis.
DET:
- Small hiccups but nothing major. Follow-up on the pipeline for DSSC and firmware for other detectors.
- Jolanta S.-D. is not aware of LPD/FXE update and will check with EEE/CTRL/FXE.
ITDM:
- Announcement: ITDM would like to upgrade GitLab on next Wednesday 18.08 from early afternoon 13:00 and may take until the evening. Users of GitLab are contacted and no access to GitLab during that
action.
XRO:
- Nothing to report. Maurizio V. will follow the HED beam instability.
LAS:
- Affected by power glitch: all PP-lasers / AMPHOS went down and warmed. LAS would need a solution for power glitches, considering power backups, UPS or batteries, as the controllers for this type of the
pump goes down.
- Jan G. says that XPD has a bunch of unused UPS and could offer to LAS.
UNSYS:
- Problem with cell6#SA3 quad mover is solved. Coupler was exchanged and it works. UNSYS has more spare parts and is in touch with Beckhoff.
- Sara C. says P. Gessler informed Karen had problem when changing undulator energies. Suren A. could not find any issue with Doocs / Unsys side.
Patrick G. talked to Olaf H. and firstly BKR must try to change energies and if it works, then instruments shall try. Karen A. says BKR could moved energy and had no issues - the issue was in HED side.
P. Gessler proposes that Unsys check with Olaf H. Further discussion will follow offline.
SPB:
- Couple of issues: 1. SBP Pop-in reached limit switch and had to be changed; 2. Affected by the PP-laser downtime overnight.
- A. Koch says there was about 0.5mm steps lost. He is looking into it if it is mechanical, motor, or control issue.
FXE:
- Wajid E. says work on the clock and control is ongoing for the LPD.
MID:
- Al fine and use of PP-laser is not needed currently.
HED:
- Nothing else to report besides of what was discussed during Unsys report.
SCS:
- Not present.
SQS:
- Not present. |
