General Announcement:
- Wajid E. reminds DOC is not working this week but the DRC will take the calls over the week and redirect to respective OCD inside DATA department.
- Olivier M. mentions to use drc-xfel@xfel.eu for contacting the DRCs. However, the fastest way to communicate for urgent matters is using the regular DOC/DRC phone number.
- Martin D. updates the status of winter maintenance period: 
1. MTLs are in general with lower quality as compared to previous maintenance time (e.g. starting and ending dates); 
2. Groups will be contacted back by XO and meetings with groups will be scheduled in the coming days. 
- A. Galler shows the TTFinfo/schedule to inform on the schedule for this Blue/FD week starting today.

EEE:
- Nothing to report.

SPB:
- Nothing to report.

FXE:
- PP-laser sync problems (6x last week) with loosing timing. It put the PPODL device into Error state; it could be recovered automatically but the laser timing wasn't conserved.

MID:
- Thanks to VAC for borrowing He bottle.
- Problems with optical sync; otherwise all fine.

The pressure in the line will be monitored and the valve will close if unexpected drop happens. If one needs He gas please get in touch with XO.
- Winter maintenance task list: XO has received almost all lists apart of two of them. Groups missing shall submit the maintenance task list as soon as possible.
- Zunaira A. informs that if SEPS/AIBS is triggered (like last Saturday event) the procedure is to send an e-mail to rpo@xfel.eu.

CTRL:
- Follow-up of MID mirror feedback: problem is hard to replicate; yesterday happened again and recovered itself. MID reports it is stuck at exactly this moment. CTRL will investigate.

DA:
- Nothing to report.

EEE:
- Nothing to be reported besides the Saturday issue with SXP losing power which affected the AIBS. Zunaira A. says devices are in the UPS system (Pandora, which did not give alarm).

the confirmation if they take place depends on the actual time available for the work. 
A. Galler informs that a presentation wad done in this meeting series and also to the STGL who shall also communicate to their respective groups. It is also perfectly fine to mention that a task may not be

General Announcement:
- The accelerator is down since Sunday morning. An oil pump of the warm compressor failed at around 7;00AM. In the afternoon a temperature of a cold compressor bearing raised and had to be exchanged. 
Cryo OK is expected today at 22:00. The operation for the current week will be updated by XO as soon as news are shared. 
- Harald Sinn as PRC informs the SA3 pointing is not so perfect (issues with crosshairs). Center of aperture is currently being used by SCS. 
SQS still has to find if actual position is good. When A. Koch is back this shall be revisited.

LAS:
- FXE reported PP-laser to have long pulse duration and small beam profile at hutch. LAS is discussing and investigating with FXE. An update will be done by end of the day.
- SA3 PP-laser: SCS reported not been able to open instrument hutch. A restart /re-cycling of laser interlock was done and worked properly, consequently shall not be the issue's origin. 
SCS shall contact SRP and Lasermet. A proposition is to use dummy connector but needs to be discussed with SRP.

500uJ.
- DOC shall run OK for operation regarding the number of available staff members. It includes people working remotely.
- SEPS interlock was approved last Monday and Tuesday. For questions please get in touch with Zunaira A.
- Harald Sinn as PRC reports: 
1. that yesterday there was a malfunction at SA1 and SA2 hutch search; together with Eric Boyd and Desy colleagues a fast replacement of devices was done; 
2. A confusion between change from SQS and SCS: not clear what time the change would have to be made and it was finally decided to do this morning; it requires Theo involvement.

CTRL:
- Follow-up of SA2 VAC loop: EEE changed the timing for the triggering updates and it seems to have improved; no slowness was seen since them. A fine tuning of the parameter will be made.

DA:
- Nothing to report.

EEE:
- Finishing the handover activities;
- PLC team working with CTRL to mitigate VAC loop issues;

MID:
- EPS system triggered limit of 300 pulses; It seems to be related to a foil / diamond detector system. MID was not informed of this change in EPS. 
Nerea J. informs that the new entry at EPS was a request from XPD. Harald S. says an option is to the machine to increase the EPS to 360 pulses.  
- RF window was allowing only 272 pulses and not the requested 352 pulses.

HED:
- Nothing to report.

SCS:
- Not present.

SQS:
- Alberto Defanis says that the new mirror region found is not fully understood by SQS staff.
- Problem with the digitizer: shows an artefact and a discussion with the manufacturer is ongoing and may require its intervention. EEE is on the loop.
