General (T. Haas)

• Due to problems with interlock cabling the approval date with the TÜV on 1 June has been cancelled
• The MB, SASE1 Instruments, AE, CAS  and PSPO met yesterday and agreed that in view of the schedule risks with technical commissioning the focus of the next weeks should be enabling both FXE and SPB/SFX to accept beam for doing radiation safety measurements no later then end of June.
• SPB/SFX were asked to identify the minimum functionality for this goal. The respective components will be marked in the component priority list

FXE (A. Galler)

• So far work has concentrated on motors
• This week PSLITs and BIU2 successfully underwent E2E tests
• JJ was back this week to fix some problems on patch panels
• Johan spectrometer is back in the hutch

SPB (B. Weinhausen)

• Work continued on the tunnel loops.
• The power supply problem with photonics cameras has been solved by AE (Additional 12V terminals installed)
• Triggers for the cameras are working
• Valve between optics hutch and tunnel vacuum was opened for the first time
• There is still the unsolved problem with the TECHNOSOFT motor.
• Work will now move to the optics hutch.

Laser (T. Jezynski)

• Alarm systems are (smoke, gas etc) are now connected
• Big problems with AC systems. The effort with FM to stabilise the humidity now results in temperature swings of up to 2 degrees. The same problem also appears in the instrument laser hutches
• AC problems lead to large instabilities of the laser
• Alignment beam is now delivered to both instrument laser hutches
• No new information was received on the topic of optical synchronisation

Detector (M. Kuster)

• Management decided that LPD will be moved to FXE in June, in weeks 23/24 to allow further testing of AGIPD in HERA-S
• Interlock test on AGIPD continue
• CAS is working on integrating the DAQ of AGIPD. When this is done an update of Karabo is needed. This will not happen this week and hence not before S. Hauf is on holidays

Electronics (P. Gessler)

• There is still some work for the tunnels:
• For integration of MCP tests were done in the lab yesterday. One of the two axes is working, the other one not yet
• Tests for PBLMs could not be done as there was no common window between on N. Gerassimova and M. Umar. Tests could be done by M. Umar if N. Gerassimova agrees. She is on holidays for two days next week
• The interface of the vacuum loop and the EPS loop to the DESY MPS requires additional work for XTD9 in the next days
• Work also continues on AGIPD for one more day
• There are some absences due to sickness and holidays that also slow down the work

Karabo (A. Silenzi/B. Brockhauser)

• There will be a swap of the GUI server today to allow debugging the issue that the device states are sometimes not properly shown. People will need to re-connect
• Tests of TECHNOSOFT motor were successful. (Does not include encoder needed for SPB motor)
• There is a fundamental problem with the Photonics camera used in the SR imager. It has a rolling shutter that does not allow to get well-timed, triggered images. The same issue might be persent for the HIREX camera
• The KARABO/DOOCS driver has been re-established. This should allow to set time delays directly from Karabo again

Discussion/Next Steps

• SPB should start with technical commissioning of OPTICS hutch
• Instruments identify components needed for beam in the hutch for radiation safety measurements
• AE finishes pending tunnel work and then focus on SPB/SFX and FXE
• Displatch meetings on Monday and Wednesday at 09:30 in XHQ/MCR (*not at DESY*)
