XRO:

- Working at BKR yesterday with commissioning SA1 alignment; SA1 is aligned until SPB and FXE.

- Today continuing with SA2 depending on beam stability.

- Idoia F. mentions that computers were not running at BKR. A check after shutdowns and prior operation is welcome.

LAS:

- The AMPHOS in SA3 needs a new power supply. Expected delivery and exchange on Friday.

- PLC update in SA3 and uTCA upgrade on Friday.

- Advancing with SA1-PPL commissioning.

- LAS will send e-mail to Zunaira A. for that MEA3 personal is contacted on the problems with sensor boxes.

UNSYS:

- Ambient field coil was fixed.

- New minimum gaps will be calculated and communicated to XO.

SPB:

- After interlock test last week there is an issue with the new DACHS terminal. The hutches can’t be accessed. Pouneh S. says DACHS is working but this particular new terminal might not be activated in the system. An special permission must be given. Tobias Haas will be informed to contact MEA3.

FXE:

- Martin K. will ask FXE colleagues on YAG screen information. Currently he is not aware when this happens (similar event back in 2019). 

MID:

- all fine.

HED:

- all fine.

SCS:

- in contact with Eric B. to get the beam shutter back on Friday for closing hutches during the weekend.

SQS:

- Early next week review with the digitizer engineers.

- Pouneh S. asks that laser interlock in laser hutch does not work. The new parts have been shipped and arrive soon. Together with TS electrician one has to exchange the relay. Daniel Rivas is informed.

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.

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.

- Temporary tunnel access requests: for ZZ access please be aware of the new Redmine ticket for access requests. The link to it appears in the BKR E-log.

- Use of FFP2 masks in experiments control hutches:  Sandra Plett informs rules such as temporary stop of work after 75 minutes of mask use or a day off after two working days with masks are not mandatory - these are only a recommendation; If two people are <1.5m, one has to use masks. While Seated or alone you can remove the masks; However, if there are people running around, please use masks also if seated; The wearing time is just a recommendation - it is not mandatory to make the break.

- Jan G. asks when would be required by the earliest. K. Wrona says they need to copy a lot of data before the update and it is estimated in two weeks (+-2 days), to take place in the second half of February.
