- Saturday evening in SA3: failure of fast valve controller for interface to Desy. Access by VAC-OCD and PRC was needed to exchange the controller and beam interruption of 4.5hs in the north branch 
happened (investigation + access). 
Rack 3.1 was affected (located behind the concrete wall at the dump).

XPD:
- All fine with XPD.

DET:
- Nothing to report.

ITDM:

- Pre-announcement: 
1. upgrade of InfluxDB to happen during the winter maintenance period; 
2. today the update of Graphana is taking place at a proposed time 15:00 (service down for a short period). An e-mail will be sent and in case of any concerns from other groups it may be shifted to next 
Monday.

XRO:
- Nothing to report.

LAS:
- Regular maintenance and tests being carried out today.

SPB:
- Good data were measured last week.

FXE:
- Nothing to report; experiment was successful.

MID:
- All fine at MID.

HED:
- Apart of small issue last Friday, nothing to report.
- Transmission with MONO was too low and HED decided to stop using it during the weekend. 
- J. Gruenert adds the recalibration of SA2 XGM has to be done when changing beam path or alignment of beam.

SCS:
- Preparation for beamtime; issue with motion being addressed.

SQS:
- Not present.

General Announcement:
- A. Galler informs groups are very welcome to contact XO for questions and discussions on the electrical maintenance task taking place on 3rd of December.

Please instruments are asked to make use of it for that a database can be built to further investigate correlation between beam quality and environment and operating conditions.

CTRL:

DA:
- Nothing to report.

EEE:
- Nothing to report.

VAC:
- Nothing to report.

XPD:
- All fine with XPD.
- As PRC J. Gruenert informs machine had trouble on Monday while switching to 14GeV, which took longer time than planned. As consequence tuning started later on Tuesday. 
The HXRSS tuning is starting only this morning. The SA2 regular SASE intensity is still low but SA1 and SA3 runs fine.

DET:
- Nothing to report.

ITDM: 
- Nothing to report.

XRO:
- Nothing to report.

LAS:
- Nothing to report.

UNSYS:
- Last week SA1/cell27 PS encoder motor was replaced. Suren K. says Unsys still has 5 spare motors to be used in such cases.
- Issue with stages of the Monochromator crystal in second chicane of SA2: X-axis, Y-axis and roll angle have to be controlled in local mode as encoders are broken. 
Crystal was inserted this morning into beam by Unsys staff using the local controls. Roll angle can not be seen in the camera, only Y and X-axis can be seen in camera with accuracy of 0.5mm.

SPB:
- Nothing to report.

FXE:
- Test on digitizer of a motor that worked nicely.

MID:
- Special thanks for support from Suren K., HXRSS team and XO during the weekend for providing HXRSS beam.

HED:
- Nothing to report.

SCS:
- Theta rotator last week: experiment last week went fine and motors are working.

SQS:
- Nothing to report.

General Announcement:
- F. Wolff-Fabris as PRC says beam delivery is working fine and only last night it was interrupted for about 1 hours due to an issue with RF system. 
SA1 and SA3 beam is running in good performance and currently the HXRSS in SA2 improved as compared to yesterday and has achieved around 500uJ with 100uJ SASE background as of now.
- Gero Flucke as DRC says all is fine but suffering with shortage of people in DOC.
- A. Galler says that please contact XO for information/question on the power cut of December 3rd.

CTRL:
- Nothing to report.

DA:
- Nothing major to report.

EEE:
- Nothing major for the moment to report.

VAC:
- Not present.

XPD:
- No issues to report. All fine.

DET:
- Jungfrau issue reported by FXE: the detector was not expected to be used in burst mode and this probably caused the issue. The burst mode is not yet optimized (some experiments/tests were done At SPB) 
and this was not prepared at FXE.  

ITDM: 
- Nothing to report.

XRO:
- Nothing to report.

LAS:
- Issue with SA1 PP-laser: trigger delay device at the instruments showed issues and yesterday a patch was deployed and it works now.
- SPB requested improvement in the beam shape and LAS colleagues are working on it today.

UNSYS:
- All fine.

SPB:
- Nothing to report.

FXE:
- A. Galler informs a new He gas delivery in on the way to EuXFEL.

MID:
- DOOCS device crashed overnight: e.g. information from the undulator was lost and the clone device was gone. Fixed by DOC. 
Wajid E. and Steffen H. comment that the "refresh" button helped to re-start; the server that runs the clones for MID crashed due to unknown reasons and the refresh button worked; reason under 
investigation.

HED:
- Nothing to report.
- HED will need XGM next week.

SCS:
- User operation and issue with theta rotation of a chamber. SCS will contact EEE and CTRL.
- Question on ReadtheDocs problem: SCS uses with users for documentation and shows malfunction. 
K. Wrona comments that the servers were put in operation but software is not in good state and not easy to fix. Progress is being done with preparing a workaround. Once a strategy is known ITDM will inform 
accordingly. 

SQS:
- Nothing to report. Estimation for pulse duration during last week: Alberto De Fanis will find out internally and inform accordingly.

General Announcement:
- Processing of the maintenance tasks lists is delayed but effort in background is ongoing. Lists will not be published next Friday and scheduling meetings will take place during this and next week. 
The release will take place on November 11th.
- As PRC, A. Galler says that nothing major is to report apart of the laser interlocks issues on Thursday and Saturday, fixed either by SRP or the instruments.
- A. Galler inform on the e-mail sent to the xo-info@xfel mailing list on the the beam quality device at Karabo. Instruments are very much invited to use it at least once per shift or when beam conditions 
change.
