General Announcement:
- It had been a cooling water issue with SA1 and SA3 PPLs on Saturday. Other groups are encouraged to check their components for eventual damage. Cooling water is back
again.
- Change on definition of a critical work: everything that leads to operation is from now on considered a critical work (official communication will be send by e-mail).
- Tomasz J. says interlock tests in SA1 tripped the laser interlock due to the Seeder connection to the interlock.
Andreas G. says there are care been taken to prevent this in future. More discussion will follow.
CTRL:
- Updates were done on the time servers and data loggers.
- GUI servers will be done this week as there was no access to GITLab. Current suggestion is next Wednesday morning before 08:00AM.
Each topic will take a few minutes only. XPD is fine with the proposed day/time.
DA:
- Nothing to report.
EEE:
- Issue during weekend: signals to the absorber. EEE and PRC (Maurizio V.) will coordinate when it is the best time for applying the final fix.
EEE needs to mask it for proceeding with the work.
VAC:
- VAC OCD was involved in the absorber EPS issue.
- Today around lunchtime the XTD6 and XTD9 will be closed.
XPD:
- EPS issues: any component driven to the beam was not protected by many bunches operation. The EPS was thinking the PNACT was closing but in reality, it was opened.
PRC/EEE/VAC/XPD OCDs solved by manually telling the system it is closed.
- Wrong bunch number sent to XGM: SA3 toroid was moved to a different position and the old name was not valid anymore.
Info from this toroid was not received and the consequence XGM was receiving wrong bunch numbers. This makes impossible for the XGM to calculate correctly the number of
bunches.
Doocs servers were not updated (these programs would need to be informed of new naming).
- Andreas K. says that XTD6 is clean. In XTD9 an intervention by EEE will take place. Bruno F. says that it is a simple task and we are accessing tunnels right now.
- Operation E-log 2021 is missing and must be created.
DET:
- Offline calibration work is ongoing until tomorrow morning.
ITDM:
- GPFS offline storage maintenance to be done today.
- ITDM was notified by Desy that is necessary to reboot logins on Maxwell nodes (between 11:00-12:00).
XRO:
- Nothing to add to what was discussed on the EPS.
LAS:
- Affected by water cooling incident. SA1 came up without issues but in SA3 there is problem as AMPHOS did not restart.
- Trigger issue on last week are not the issue anymore. This was not repeated (but SA1 still on local mode).
UNSYS:
- BBA and photon BBA last week: new values to be implemented and minimum gaps will be updated accordingly.
- Frank Brinker tested the ambient field corrections. A ZZ is taking place this morning to fix SA2/cell12.
Few other coils have different polarities and will be fixed today or in another ZZ.
SPB:
- Preparing for the first two weeks with beam in March.
FXE:
- Aligned the cameras in FXE mono.
- Crates to be installed in the rack room.
MID:
- Joerg H. raises the question on the FFP2 usage recommendation. Sandra Plett says the document containing guidelines will be prepared (hopefully today);
It is mandatory to use FFP2 masks if you are not alone; it also depends on the room size and at the moment it is 3-5 people in the hutches with mandatory use.
A. Galler says these are the current regulations and maybe this will change in future.
HED:
- Nothing to report.
SCS:
- Nothing to report.
SQS:
- Trying to get a new DAQ and will talk to ITDM. |
