6. In case of questions please contact xo-planning@xfel.eu

- As PRC, Jan G. mentions a full report for the weekend events is available at the Operations e-log: 
1. events on Saturday limited SA1 and SA3 to a max of 30 bunches combined; caused by communication failure by the EPS - partially solved on Saturday but happened again on Sunday afternoon. 
EPS loop was solved by replacing a communication terminal; The MOV loop relates to a terminal seemed to be burned (redundancy was working) – this needs to be worked on Tuesday's ZZ. 
Limitation of 30 bunches came as communication was lost. Recovered after the work on Saturday and Sunday.
2. Broken bridges Karabo-Doocs went down on Friday evening: not caused a beam downtime but photon devices could not be seen at DOOCS. 
A Desy CPU at the injector building failed and Tim Wilksen intervene to restore the bridge and will follow-up.

• SA1 pulse energy will be lower than possible, because of XGM settings that need to cater 7.8 keV and 12.5 keV

General Announcement:
- An e-mail was sent to "xo-info" mailing list concerning the cooling water maintenance scheduled for one week starting on Dec. 6th. 
More information will be sent by the end of this week and if you have any concerns, please contact us at xo-planning@xfel.eu.

CTRL:
- Shimadzu camera at SPB to be followed up; Also, the pop-up motor at HED needs a feedback.
- Related to DRC: on Friday SQS was using the bunch patter server and the machine server was going back to zero pulses. Cause was another Karabo device at SCS topic which was working / forgotten and was 
setting bunches to zero. 
Important is that none was knowing this was running. Follow up with XO for new procedures.

DA:
- Nothing major to report.

EEE:
- PLC side: backlash 2 step compensation successfully tested.
- Cabling at FXE had some troubles and today there will be a recheck.

VAC:
- Friday incident with Interlock on SA3 (faulty gauge at GATT): reason is known and was communicated to the involved parts. Long term plan to mitigate is in place.

XPD:
- Involved at high energy tests in SA1 and SA2; SA1 worked well delivering beam at SPB; SA2 had 300uJ in XTD1 but a high intensity at HED was not achieved. On Sunday HED colleagues did some tests; 
Calorimeter did not see beam.
- Imagers YAG imagers could see the beam at the end of HED station. YAG is not too bad at these high energies (only factor 2x less). Diamond is not suitable as one needs to integrate lot of pulses to get 
signal.
- Upgrade on Imagers together with Andrea Parenti is already concluded, tested and shall be working fine. Some Karabo devices had to be restarted in SA1, SA2 and SA3. In case of issue, please contact 
Andrea Parenti.

XPD:
- As PRC Jan thanks all people who helped to restore SA and SUN (two power glitches around 7AM); Also Desy/MKK confirmed that machines were briefly affected. EuXFEL accelerator recovered quickly.
- Consequences on SAT: 1. Power went away of whole SA3 area; 2. Tunnels mostly not affected but water cooling pumps were switched OFF (affecting also balcony rooms). 
One auxiliary pump did not turned ON and several hours later (10-11AM this was too hot) and brought down services. SA2 tunnel cooling water temperature raised but on SUN it was faster to act/recover (MKK; 
30mins).
- XGM at XTD6 went down.
- MKK does not see the temperature but only humidity. To be implemented in the coming days.
- SA2 Karabo totally down.
- Interlocks went down (EEE, D3, SRP) and had to unblock radiation alarms. A Desy mTCA crate went down and had to be manually power cycled (due to cooling water lack at balcony room).
- PP-laser in SA3 went down. SA3 experiment at SCS was cancelled at the point.

DET:
- No specific feedback for DET; shall be OK.
- Broker pile up was not fully understood. SA2 was restarted and back to normal; MID restarted yesterday and will get in touch with them.

ITDM: 
- Cooling issue: discovered by alarm (Kimon who informed MKK); it needs a better procedure to inform MKK.
- After 30 mins called from MKK saying T was going down, but due to open doors.
- Steffen H. says a report has to be done with goal oriented to avoid this in future.

XRO:
- Looking into systems: in tunnels, if power is OFF then mean cooling shall be OFF. Cameras do not work remotely (connection to servers; only one is accessible).
