• 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.

​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.
