EEE:
- Downgrading clocking and control firmware today after this meeting. For questions please talk to Bruno F.

VAC:
- Power glitch propagated to the tunnel (shortage of cooling water) but it did not affect VAC systems 
(update 10:30AM: GATT-SA3 injection of gas stopped due to the water shortage being above 5-10seconds but less than 30s, as pumps continue running - SCS could set it up again quickly). 
- GATT loop: Steffen H. and Raul V. are setting up update and please refrain to use it today.

XPD:
- Issue with XGM in SCS hutch: it got shock vented with N2 last week. Fortunately, high voltage was not ON. Turbo pumps have issues with controller; on Thursday and Sunday the pressure gauge dismounted. 
XPD is on contact with SCS on it. 
Remark: Theo M. is on holidays and for XGM issues please contact Jan G.
- A. Koch asks Steffen H. if the Lima/Bassler camera fixes uses only DAQ and not GUI. Steffen H. says this is correct and for Karabo 2.11 only. A. Koch will send a list of cameras to Steffen H. 

DET:
- Nothing to report. DET aware of clock control downgrade.

ITDM: 
- Today afternoon ITDM starts activities in Influx: downtime of few minutes.
- Reminder on closing proposals: Please do it ASAP. If not done by next week a policy on non-accessed data will be done.

XRO:
- Nothing to report.

LAS:
- The cooling water for SA1 and SA3 AMPHOS went down on Saturday morning, bringing PP-lasers - due to another power glitch on SAT early morning. 
- Cooling water in the LAS R&Dlab remains down as of now.
- PP-Lasers will come up this afternoon but requires time to thermalize. It was put OFF in a controlled way this morning due to the timing system maintenance. The AMPHOS was not OFF during today's power 
glitch.

UNSYS:
- Issue with cell6/SA3: power cycle of whole cell is ongoing. Suren K. asks if a possibility to go to tunnel can be done. ZZ is not yet requested but will contact PRC to fix the coupler.

SPB:
- Complications with the delivered bunch pattern last week: coincidence of needing to drop bunches for detectors commissioning at same time SCS use particular bunch pattern. 
Nevertheless, it worked well enough for getting data, apart of few lost time to set the pattern.

FXE:
- Nothing to report.

MID:
- All fine at MID.

HED:
- Nothing to report.

SCS:
- Not present.

SQS:
- All good at SQS.

General Announcement:
- There was a power glitch last night around 10:30PM at the Desy power distribution. XHQ and XHEXP1 seemed to be not affected - probably devices that gets cooling water from Desy could be affected. 
Please inform XO if it is found any affected equipment in the XHEXP1 side.
- Raul V. asks on the fix CTRLs has applied to the vacuum issues last week. Steffen H. will give details offline.

CTRL:
- Bi-directions of clones may not have been working properly and CTRL is investigating and preparing a solution for it. 

DA:
- Nothing to report.

EEE:
- Small issue with FXE timing (strange behavior of RTMs). It happens when communication to main timing system is interrupted and it affects mainly the FXE PLCs. Result is that devices may not correct 
trigger.
- Cable installation currently ongoing in HED and scheduled at FXE (cw33). 

VAC:
- Last night status of critical pumps was checked and seems that there was not water interruptions (very first time for a power glitch). These pumps stay working normally during the night.

XPD:
- No issues to report due to the power glitch.

DET:
- Jungfrau activities at SPB were delayed because of beam delivery issues with the number of bunches.

ITDM: 
- Nothing to report, also regarding to the power glitch.

XRO:
- Not present.

LAS:
- Unaffected from the power glitch. PP-Lasers are working.

UNSYS:
- Everything is fine with Undualtors.
- SA3/cell6 quad mover has a problem unrelated to the power glitch. As agreed with BKR, it stays as it is Monday when corrective actions to recover it will be made.

SPB:
- Beam delivery problems yesterday regarding the bunch number: A. Galler says that accordingly to W. Decking, when running in interleaved mode it may cause that problem if the suppressions does not work 
correctly. 
Further investigations are under way by MXL. If this is an issue for equipment BKR can install an interlock on the Big Brother and probably a detailed discussion with interleaved mode instruments can help 
in this direction.

FXE:
- Nothing to add.

MID:
- Looks like the beam today is very unstable. Data were collected and the stability task force will be contacted.

HED:
- Nothing to report.

SCS:
- Not present.

SQS:
- Yesterday a situation happens when 1 PLC went OFF unintentionally, causing a pump went OFF afterwards. SQS asks if this can be followed in a way the pump does not goes OFF in such events. 
Raul V. comments that 5Hz turbopumps at the tunnel have a configuration to prevent it by disabling the automatic switch in the component configuration. 
Nerea J. says that they can take both tunnels and SQS used configurations to bring them together. 

General Announcement:
-	 

CTRL:
- Deployment announcement: there are two more motors to be updated on ARAVIS cameras (photonic and Bassler). CTRL proposes to do this afternoon. 
Cameras devices will be down after update, aimed to enable train-ID corrections. Please instruments check on Tuesday if cameras are back.

DA:
- Nothing to report.

EEE:
- uTCA CPU in SA1 balcony room is not reachable. Bruno F. is investigating.
- CPU of LOOP16-SQS is not reachable. Nerea J. will check it today.
- Issues with LPD and AGIPD are being tested in the lab and the check at FXE will be done later today.

VAC:
- Some OCD calls related to instability of SA3 vacuum loop. DOC is informed and shall be working on that.

ME:
- Alberto De Fanis asked if ME is present, willing to discuss topics. A. Galler says group was around a couple of times and if groups have questions please use this meeting series to address.

XPD:
- No issue to report.
- Steffen H. will check if some XPD tunnel devices are affected by the ARAVIS update.

DET:
- Nothing to report.

ITDM: 
- Influx problem on Thursday (disabling live-view on Karabo): with help of Influx data support this was fixed. The cluster is up and running well. 
The part of the old data during the time it was down was written by Grafana and will be synchronized back to the cluster during this week (tests are needed).
- Following on Friday for the Influx third node that went down (not related to the previous incident): DOC was blind for a couple of hours. Investigation ongoing. It's not related to Grafana. 
Instruments were not affected.
- Reminder of reviewing and closing proposals for the second half of this year. Please look at the sent e-mail and make a cleanup. 

XRO:
- Not present.

LAS:
- All PP-lasers are running.

UNSYS:
- Issue with phase shifter in SA3 for the 3keV use: problem is that at 14 GeV the tables of phase shifters go to 25.3mm gap and this is in the upper limit for making 3 keV. 
Phase shifter tables will be extended to a larger gap. Better to use 3keV at higher electron energies.
- For the UOM's mention on the update of phase shifters on the chicanes, this has to be prioritized. XO will discuss with Sara C.

SPB:
- Minor issues with SPB imager being saturated. A. Koch adds that it will be followed up and he is aware and will analyze better.
- Organization limitation: RF discussion for last weekend. The BKR / Operators were not aware they would use 404 bunches and costed 2 hours.

FXE:
- Nothing to report.

MID:
- All fine at MID.
- Laser went down for 12 hours due to the issues with HED interlocks on Wednesday (action taken due to the restart of laser interlock performed by SRP).

HED:
- Not present.

SCS:
- Issue on the scanning speed of monochromator. Parameters will be adjusted with Marijan S. today.

DA:

- Nothing to report.

EEE:

- Cables available for HED to be installed next week – date to be discussed offline.

- Fast electronics side: working on FXE and HED issues;

- Nerea J. reports on the VAC/SA3 issues: instability with devices going into an unknown state. Alessandro S. works at the night shift in the DOC and will try to fix a permanent fix during the night.

VAC:

- SA3 issues are affecting also the gas attenuator (not only general SA3 vacuum loop but also GATT is affected, which has its own loop). There are no physical events - seems to be electronic. Stability issues to connect devices; Seems to be more related to infrastructure (PLCs). Further investigations are needed.

ME:

- Not present.

XPD:

- SPB imager: change setting of motors (it shall work now) and next week when A. Koch is back further investigations will be done.

- XTD9 IMG: currently working but a permanent fix is welcome in the future.

FXE:

- Not present.

MID:

- All fine.

HED:

- Major issues with Agipd detector yesterday (thanks to DOC for help): 1. Could not kill the service and CTRL investigated; 2. Clock and control did not work (it has worked at CFEL last week). The issue was solved by changing the clock controller back to old configuration (EEE helped). Bruno F. comments that the clock control had to be downgraded in this detector (it worked in other detectors, only this one did not work). Further investigations will follow.

SCS:

- Change of speed from the monochromator was not possible. EEE and CTRL are working on it.

- Next week will run with a special train picker / bunch sequence pattern as the one used last week.

SQS:

- Vacuum problem as mentioned.

- Commissioning DSSC for future beamtimes.
