Focus of meeting is on SASE1 Instruments, Laser and Detectors

SPB (B. Weinhausen)

• All motors in the SPB tunnel loop have been commissioned except for one TECHNOSOFT motor where the updated driver was not yet available
• Comment by P. Gessler:
  • The updated MC2 lib was deployed yesterday evening. Testing should be possible now
• The second camera of the screen broke. Concern exists over possible overvoltage in the power that comes directly from the PLC
• All encoders are working
• The vacuum in the Optics hutch is closed
• Info by A. Violante:
  • All cabling in D02/D03 is done
  • There are a few damaged connectors that prevent pushing in the modules. This should be fixed on Monday
  • Pins are swapped in one connector. Will be fixed locally
• Comment by P. Gessler:
  • This week AE was busy with AGIPD and tunnels
  • Next week resources should be available to support start of commissioning loop 1 

FXE (A. Galler)

• E2E tests are progressing 
• A recent update of the Beckhoff firmware generated new problems with encoders
• Info from T. Korsch:
  • The vacuum in the hutch is closed and has reached 5e-7 mb
  • There is a minor leak in one of the bellows
  • Compressed air is working to operate the gate valves
  • Vacuum gauges can be read out remotely
• Attention should be paid to being able to read out detectors, e. g. diodes

Laser (D. Kane/M. Lederer)

• Slides were provided in INDICO with a detailed account of the status. Only Key points are summarised here:
  
  • Hutch infrastructure is working in general and temperature stability is ok but laser group is lacking access to controlling the parameters, humidity is oscillating and smoke detectors are not connected
  • Pre-assembly of PP laser is 75% done
  • Beam delivery to instruments is on the list now
  • Synchronisation with optical system might not be available before October
  • Control are generally working and software has improved a lot but some stages cannot be controlled and Karabo appears still to have some resource leaks

Detectors (M. Kuster)

• LPD is in E2E tests and AGIPD is still being integrated into the XFEL environment
• This week it was possible to run the DAQ chain on LPD for the first time
• All tests on LPD including data taking in the X-Ray chamber in HERA-S should be done by end June
• Situation with AGIPD is more difficult as basic integration is still not complete

Discussion

• Follow up on progress with instruments, laser and detectors will continue in S1R meeting from now on
• The S1R dispatch meeting takes place on Mondays 09:00 in BKR and on Wednesday 09:30 in XHQ 
• Groups that require help from AE and CAS and that need to coordinate with other activities should attend
