FXE

SPB/SFX

• few days of beamtime remaining, no particular issues
• preparing for emergency power off
• preparing shutdown activities with EEE

SCS

• beamtime, no particular issues.
• preparing for shutdown
• XGM is supposed to run even despite the emergency power off ==> M. Teichmann is in contact with T. Schoen (TS)

SQS

• beamtime, first scattering images taken using the pnCCD!
• preparing for shutdown, in particular some cabling together with EEE

 MID

• Integration of the LDM: Safety document is needed. ==> This is needed ASAP!!! ==> THIS IS STILL NEEDED!!!

​HED

• CAS was able to follow up regarding the request for test of triggering / pulse on demand from this Monday. HED was kind of lucky, CAS would appreciate some further notice next time...
• Due to missing endswitches / interlock conditions, some YAG-screens have been burnt. HED would like to try to get this fixed in the tunnels and the hutches still in this shutdown by installing endswitches etc., to be negotiated with EEE
• The bias teeth(???) used by HED are not being supplied any more, new ones are not performing ==> to be checked with other instruments / EEE, Sato-san was suggested as another expert to ask.

Optical lasers

• everything fine, thanks for the support!

VAC

• Requested to see the first pump + valve of SPB/SFX ==> to be clarified by VAC, SPB/SFX + EEE

• 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.

TS

• From CAS: TS should not rely on email alerts to monitor the cooling of the servers running for example the email services...

AoB

• In SASE3 the apertures of the GATT have to be realigned. The upstream apertures have been alreadz realigned. The downstream ones will be probablz realigned tomorrow. If not succesfull some restrictions of the operation have to be evaluated.

FXE

• Loops update has to be coordinated between EEE and FXE. No feedback received from EEE. AG will remind TKorsh. 

SPB/SFX

• Loop updates continue.
• Loop 8 will be commissioned on monday with EEE.

SCS

• 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. ==> there was no meeting on Friday. Still pending.

CAS

​ITDM

• Additional CAT connections planned for SQS, FXE, SCS were installed and approved by ITDM.
• During the maiinenance of the cooling water system the doors of the balcony rooms and racks were left open to cool down the electronics. Although in the past that worked, it is no longer the case. ITDM will discuss with MKK2 how to make the cooling of the balcony rooms more efficient during planned mainenance of the cooling water system or in case of emergency.

On Monday Torsten Schoen informed AV that the power went off in MID and HED experiment hutch because of the radiation interlock test. This was due to the fact that according to the original plan (circulated and approved at the beginning of May), the SASE1 test was supposed to happen on Monday and the SASE2 test the day after. On monday, SASE1 system was accordingly bridged to avoid issues with the power. A last minute change in the plan was agreed between MID and MPS but the info unfortunately did not reach Torsten, hence the issue. Also, nobody from SRP, D3, HED was timely informed. 

There was obviously a lack of communication that has to be improved. AV will write a report and circulate it to the involved people for review and provide it to the MB.

SPB/SFX

• CRL implementation in the hutch. Cables at the back of the crate have been re-shuffled by EETf. VAC vessel had a leak and is being re-sealed and pumped. If everything is fine and the vessel can be brought to the hutch the motors test can in principle start already this week.  Interaction SPB/SRP ongoing to define operations parameters.
• CSS Test have been started. 3 encoder connectors need to be fixed by EETf (not sure can be done by the end of this week).
• AGIPD motion. Test ok.
• Julabo chiller: waiting for feedback from Julabo to know whether the chiller is going to be repaired on time for next users. If not, SPB/SFX are trying to borrow one from CFEL. VAC interlocks would not be operational due to the different type of chiller. Needs to be evaluated and eventually take the risk (DET, SPB).

​FXE

SQS

• Loop 8 and 11 HW will be prepared by AE. Ongoing (AE/SQS coordination ongoing)
• Meeting organized by PGessler to review the recurring issues with the digitizers. The outcome is that for the next users run the zero suppression mode will not be used (only raw data - confermed by SQS). In this case, no issues are expected. In the meanwhile a general solution will be worked out.

SCS

• DSSC undergoing tests in Hera south. If OK, next week will be brought to the hall.
• Loop 13 running but incomplete. Loop 11 being prepared. Nano motion controls now in this loop. 

MID

• Smaract stages do not work propery and reliably. High priority. Has to be clarified with AE since it is not clear whether this is the same issue that SCS had and for whoch they developed a workaround. ==> BB will contact the Smaract company to address the issue.
• Loop 9 has been updated and the flow meters can now be read.
• Epix chiller has issues. Being investigated by MID and eventually replaced.

​HED

• Cables and loops for HED instrumentation. All the phase II cables needed for operation have been promised to be installed by the end of this week. Loop 5 cannot be available before.
• 2 weeks ago the HR mono loop was mistakenly updated twice and the second time parameters were not saved (Fri evening). Sat morning was fixed again. AE confirmed it was a misunderstanding because of paralle pulse picker tests. HR mono conversion factors commissioning ongoing.  

​OPT Lasers

• SA3 trigger stopped working today. PP laser is down. The timing server in the balcony rooms was found to be down. BF is investigating what happened.

​XRO

SCS

MID

• It is reported by CY that, in order to advance with the Epix readiness, would be beneficial if AE and EETF could accelerate the power system work BKF 467 crate completion (with Bernard's latest change request) plus patch-panel planning Eplan update this would be much appreciated. MFlade reports the request to his group.
• Issues with Smaract stages cables. Fixed.

​HED

• Si mono in XTD6 had problems with the pitch motor whoch does not work anymore. XTD6 was opened yesterday for intervention and the system was pumping overninght. Interlock modified not to stop operation during the night for MID. This morning ZZ foreseen to complete the intervention.
• Firmware for Loops 5 and 7 ready. KS/EET are checking whether all the cables for loop 5 have been installed. When they are, AE will be notified to switch on the loop. Same for loop 7. After the meetgin with compkany Schulz it was said that all the priority 1 cables (set by HED) will be installed by 05.04.
• XGM/Pulse picker alignment has to be checked. On monday AE will have a look.

• interlock definitions were updated.

FXE

• Last Thursday an alarm signal was heard from the control room and only entering the hutch it was realized that an additional radiation sensor was triggered, maybe due to a spike. The procedure and actual usefulness of the device should be commented on by SRP.
• An additional beamstop will be installed otday in the hutch. This requires to OGT3 to be moved.
• Performance issue with the digitizers when all 3 of them are used in parallel. AE on it.

MID

• Marjan is supporting the commissioning of components in the hutch.
• Loop11 is probably already containing all the required components. JH will send a confirmation email to NJ today.

HED

• Problems with the HV ion pump cables in the HED optics. Many of the cables failed the final test and showed sparks. KS, EET are in contact with Fa. Schulz to solve that. It is not clear whether this is a showstopper or the pumps could be operated locally.==> Fa Schulz will fix the connectors on site.
• Loop1 is being commissioned (Gauges and gate vales are included)
