General Announcement:
-	 

CTRL:
- Issue with mc2 motor (pop-up issue for step-up command): it has been identified and fixed. New version will be deployed in the shutdown. Workaround until then is to stop and restart device.

DA:
- On the slow migration/calibration at MID: it is understood as overload of cluster nodes responsible for migration; mitigated by adding two more nodes. Calibration services shall run better from now.

LAS:
- All fine with lasers.

UNSYS:
- In SA3: two encoders that were exchanged (cell#17 and cell#20) on Monday's ZZ. 
- Another PS (SA3/cell21) stopped working. Motor has to be replaced in a next ZZ (request placed). 
Suren K. also says that the whole intersection is not working (not able to recover after restart the system - Quad stays in position for operation). 
- SA1/cell14 a coupler of the undulator terminal was replaced.

HED:
- Running user experiment this week.

SCS:
- Nothing to report.

SQS:
- Nothing to report.

General Announcement:
- During the weekend there was a cryo plant failure which caused more than 30 hours downtime. This was due to the cold compressor failure on Friday evening. 
Machine work hard to get back in operation and Sunday by 06:00AM beam was available to the experiments.
- Chris Y. asks if FXE had used the PAM. It seems not to be the case due to the beam downtime. C. Youngman will contact Yifeng J.

CTRL:
- Nothing to report.

DA:
- DA is interested on the MID migration problem (discussion is following below).

EEE:
- Problem with SQS digitizer regarding a drift when looking into pulse laser pattern. Problem seems to be coming from the source; to be further investigated;
- Beckhoff PLC at SCS had a problem and will be investigated today.

VAC:
- No issues to report.

XPD:
- This week XPD will measure at HED with the calorimeter.
- XPD needs confirmation from MID if Diamond detector was used at MID.

DET:
- Few OCD calls related to the AGIPD operation support.

ITDM: 
- The MID issue seems not be linked to migration in a first analysis. It may relate with calibration. Queue was busy as many experiments taking data simultaneously. 
By the other side, there were no indications of calibration being used. Today the migration was running normally.

XRO:
- Nothing to report.

LAS:
- Not present.

UNSYS:
- Another Phase shifter (SA3/cell20) presented a problem like the cell17. Waiting for getting access to fix and investigate the encoders. ZZ is scheduled for this morning.

- Issue concerning AGIPD cooling system at MID being not very effective: there is ice formation which stopped the flow of water. This already happened once but it is not so often. 
Fix consists in flushing with dry air. Later today Detector will be running again. 

ITDM: 
- Fire incident yesterday on the labs (ITDM/EEE) was caused by a broken cooling system; the lab cooling water did not work for hours and let to problems with GPFS system in the lab as well as with servers 
(same type of racks as the ones in the rack room). 
- ITDM suggests the handling of such alarms have to be improved.

XRO:
- Nothing to report.

LAS:
- Nothing to report.

UNSYS:
- Issues with SA3/cell17: Phase shifter can not move. After rebooting PLC system one had to power cycle leading to lose half the SA3 undulator system.

SPB:
- Nothing to report.

FXE:
- Nothing to report.

MID:
- All fine apart of the mentioned Detector issue.

UNSYS:
- Issue with mono in cell 18 / SA2 self-seeding: Encoder for the y-motor is found to be damaged. UNSYS tried to fix it during several hours ZZ but was unsuccessful. Encoder is damage for the y station. 
Later a solution with stepper without feedback (only image) was put in place and this managed to insert crystal in the proper position. 
- Probably re-writing software to switch from encoder to image feedback may be a solution. The full fix need to open the vacuum chamber. 
It is not sure if this action will take place during winter shutdown. This taks will be included in ME list and involves several groups.

SPB:
- Nothing to report.

FXE:
- Nothing to report.

MID:
- All fine.

HED:
- It seems that beam @18keV was seen at the HED hutch, differently from the 30keV situation. 

SCS:
- Nothing to report.

SQS:
- Nothing to report.

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.

DET:
- DSSC activities with DEPFET ladder measurements at SQS went well; happy with acquired data.

ITDM: 
- Nothing to report.

XRO:
- SA1 re-alignment of mirror was not immediately possible and therefore done in several attempts. Started from none position but went well at the end. 
- In SA2 re-alignment was not possible (settings of mirrors not ideal and therefore drop of beam intensity); In future a second attempt shall be made with the lessons learned. In SA1 went well.
- SA3 activities went well without problems.

LAS:
- From SQS high energy fluctuations were seen at PP-L and fixed after switching to another setting. 

UNSYS:
- Motor of monochromator of chicane 2 / SA2: remotely action did not recover it. Access is needed. Suren K. needs a 2-3 hours of access (realistic time) and there is no guarantee it will work.

SPB:
- Got beam at 24keV. 
- On Saturday a problem with camera Shimadzu not communicating to PLC was solved.
- Beam drift at downstream of SA1 (mm order) was seen.

FXE:
- Preparing for Users this week.
- Work with cabling ongoing.

VAC:
- Yesterday effect of the power glitch at 15:03. VAC-OCD checked with SCS - the interlock reacted and GATT stopped for a while.
- SCS comments that the problem with GATT gave 300x more photons than expected to the sample and detector. A better safety / interlock is to be prepared. 
Raul V. says that topic was first discussed in 2019 with SQS (using the B4C block in the interlock loop for the GATT). It may require interaction from SA3 instruments, VAC, XRO, CTRL.

XPD:
- Small confusion on the SA3 XGMs during the weekend: BKR mixed the SCS and SQS XGM's not working and this triggered a few reactions on the weekend. A better way to do not mix up XGMs will be made.

General Announcement:
- XO thanks the instruments for posting in the Operations e-log.
- Jan G. says calorimeter measurements last Friday on HED hutch took place in order to measure transmission of pulse energy in the hutch and compare with tunnel HED-XGM. 
It is found a factor 2 loss - half beam intensity arriving at the end of the hutch. 
- Lorenz K. says that the Barista machine triggered a fire alarm. TN did a check and may be caused by the self-cleaning program of the machine by producing enough steam.
- Call for tasks to be carried on next Winter maintenance period were sent out to the are sent out via e-mail last Friday. Groups shall submit one group list by 30.09.2021.

CTRL:
- From tomorrow morning all the mails sent to the "controls integration" ticketing service will be offline due to an update. Please contact DOC instead. An e-mail will be sent as soon as the service is 
back.

DA:
- Nothing to report.

EEE:
- OCD calls from SQS last week were solved. 
- Nerea J. and F. Wolff-Fabris say the issue with SQS EPS is temporarily solved by now (masked signal at the Big Brother). SQS has to plan when it wants the EPS running.

VAC:
- Quiet week in terms of OCD.
- Today in the morning: please refrain to use this morning any SA3 device like GATT.

XPD:
- Nothing to report.

DET:
- Follow up of the pnCCD detector: upper part of the detector has scratches after Thursday accident. SQS will replace parts this week. The lower part of the detector has also some issues (noisy). 
It is unclear if the detector can be used.

ITDM: 
- Today and tomorrow ITDM carries the integration of the offline storage into the new system (new storage blocks; it shall be unnoticed by the users). The old one goes out by replacement.

XRO:
- Apart of the beam point instability @ HED (stochastic instabilities that appear from time to time) there is nothing else to report.

LAS:
- Change repetition rate at SA2 PP-laser this week.
- SA1 has a higher jitter than normal that has to be investigated on-site.

UNSYS:
- All fine at Undulators.

SPB:
- Running night shifts: on SAT night some X-ray trains not arriving; It did not disturb operation but a bit disturbing.

FXE:
- Lost of pulses and many issues on Saturday such as instability and tuning without prior communication. To FXE team.
- F. Wolff-Fabris says the beam became more stable on Sunday afternoon after the restart of a server and the feedback for the compression.

MID:
- All fine at MID.

HED:
- Suffered from beam jitter: measurements were done with different mirrors settings, CRL configs; MID branch. Analysis ongoing this week (Sebastian Goede).

SCS:
- Nothing to report.

SQS:
- Nothing to report.
