General Announcement:
- A. Galler informs on the changed schedule for Operation due to the difficulties with the cry plant last week: the current beamtimes are extended until Wed 07:00 and then tuning for cw49 will take place.
It is possible to have special arrangements between instruments - in such case please let XO know.
Expectation is to have delivery from 15:00 on Wednesday to cw49 delivery, but depends on the promptness of the tuning.

General Announcement:
- Martin Doering announces on the upcoming Winter Maintenance period:
1. Summary Task list was released last Friday 22.11;
2. A total of 10 working days is predicted for the WMP;
3. Dates for availability of Karabo, timing, DAQ, online storage were shown (selected period from Dec. 11 to Dec.18th);
4. Cooling water and technical gases maintenance (Dec.11th-20th);
5. Electricity: localized task in SA3 SCS exp. Hutch with installation of new emergency OFF button on January 15th: power will go OFF; Interlock tests light in all SASE hutches on January 15th;
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.
3. SRA slits and Filter are locked now until the ZZ on Tuesday or the WMP.
