- FEL Imager (YAG screen) in SA3 is found to be damaged. It was moved to a different spot for the time being.
- Ventilation in all tunnels caused beam jitter for 30-40 minutes yesterday. 
It was caused by outside humidity (not common, 2-3 times per year) that filled up the filters and clogged it with water droplets leading to overrunning of the regulation schemes of pumps; then pressure 
changed in tunnels.

EEE

• The timing uTCA will be switched off on the 24.06 between 9 am and 5 pm. ==> there are some issues with different versions of power supplies. EEE on it.
• Electrical safety regulation. From the beginning of July the new electrical safety regulation is supposed to be in place. According to this regulation the work at the back of the racks in the XHEXP1 and in the entire racks in the tunnels can only be done by certified EFK (Elektrofachkraefte) or by EUPs with an additional training. The additional training can only be provided after summer. The nomination of XFEL EFKs is suffering a delay due to the fact that is not clear who should nominate them (TS, UBR, HR?).  PG reported the problem and also the fact that no official statements were made in the past concerning the topic. THaas is trying to clarify the status, and come up with a statement and proposal in the Operations meeting.

CAS

• Release cycle for the next Karabo version in progress.

ITDM

• At 10 today the doors of the balcony rooms and racks will be opened due to short interruptions (20 minutes per tunnel) of the cooling water from DESY. This should not cause any issues. If the pomps intervention will require more time, the ITDM racks will be switched off. 

​SRP

• From SBP/SFX: Currently, it is not clear what to do if one of the Pandoras goes off. This apparently happened @ FXE on the night from Sat.-Sunday, and it took 12 hours to fix it. Update from SRP: Occasionally Pandoras trigger radiation alarms. It is not clear why. One possibility is that this is caused by electronic noise. Discussions with D3 are ongoing. Right now an expert is needed to reboot the system since it is not a simple off/on procedure, but data has to be analysed. There is a a document in preparation by SRP/D3 that will allow more people to be able to perform this procedure, but it is not ready yet. A side note is that there is no OCD agreement in place for these experts and the reboot is done on the best effort level. ==> Z.Ansari will be also able soon to reboot the system. ==> The issue will eventually be put up for discussion in the operation board. Statement from SRP is that there are nnot enough people to ensure an OCD service.
• Racks in HED outside the rackroom. They are too high and the top cannot be reached. SRP/JE/SRP will follow the issue up. ==> A solution has been found: TS will modify the existing movable stairs.

FXE

• DAQ issue reported (data not being recorded). Comment from ITDM is that this was a miro issue solved with the re initialization of the proposal. More details will eb discussed offline.==> issue fixed (it was due to a misconfiguration in the DAQ server)

SPB/SFX

• Loop 12 has to be updated
• SASE1 M3 issues with the pitch motor lead to FXE losing beamtime. EEE to follow it up.

SCS

SQS

MID

• By the end of the week MID should send the requirements for the vacuum interlock to EEE. ==> tests are ongoing. AS will organize a meeting with CAS, VAC and EEE to define a test procedure to be followed by the instruments when testing the vacuum interlocks.
• Calibration server for mid has memory problems and needs to be replaced. Calibration pipeline has to be moved to a different servers. Will be discussed offline with MID.==>

HED

• Yesterday the loop 6 was updated. There were issue with pumps switching off and causing overhead for HED. PG will investigate why this happened... ==> the procedure was clear to EEE and foresaw the switching off of the pumps at some point. This was supposed to be clear also to the instruments buy clearly it was not the case. 
• Nanocube PLC has been integrated.

EEE

• Crash of PLCs because of not a number values. The fix on the PLC side requires the update of the loops framework and can be done only in the August shutdown. By the end of the week a filtering tool will be availbale in Karabo.

CAS

• Karabo 2.5.1. hotfix is being prepared (Fixing 2 bugs in the framework and several GUI issues). ==> Done
• Tomorrow at 14:00 there will be a test of the pulse on demand feature (conditional triggers) in FXE. (AS/BF) ==> Done

ITDM

• Calibration server for mid has memory problems and needs to be replaced. Calibration pipeline has to be moved to a different servers. Will be discussed offline with MID.==> It is ongoing. In general this issue led to a loss of beamtime for MID. Alessandro suggests that in case of hardware failure there should be a joint ITDM-CAS decision/effort on what to do.
• Data migration: it was slow in the past days due to some script not being used for safety reasons. This is being fixed. Hovewer, due to the queue of old data to be migrated it will take some more time until full performance will be reached.
