Severity: Information 
Subject: Status and plans after SASE1 Status/SASE3 Readiness Meeting 

Instruments

  • SPB:
    • When PLC loops are restarted, still many device parameters are not properly recovered. This generates a lot of work for the team. Recently an entire day was lost.
      • Answer from AE: The parameters are extracted by CAS using KARABO. It is possible that not all necessary values are returned. AE is also investigating whether there are some bugs in the firmware procedure. It is pointed out that the change from 24V to 48V led to a huge amount of changes. 
    • Injector motion is now working along all three axes
    • AGIPD automatic power up procedure is now working. Tests continue
  • FXE:
    • The spurious data losses with the Gotthard Detector were further investigated. They are not resolved but they do not limit operation with 30 bunches

Tunnels

  • XTD10/SASE3
    • All vacuum sections are connected, locally tested and ready
    • Part of the interlock system is also ok. A global test of the entire integrated system still needs to be performed
    • The biggest challenge was the gas attenuator section with 7 turbo pumps. All pumps were locally test and integrated into the control system. The vacuum is very good (10-9) Now they are put into a  safe state.
    • R. Villanueva would like to be informed in case whenever the interlock in XTD10 is broken so he can inspect the system
    • XGM is connected to the overall vacuum and tested. The interlock is working and it is also connected to DOOCS
    • The two imagers requested for first lasing (SR/FEL) are available
    • Approximately one shift would be needed to take care of a few remaining tasks before first lasing
  • XTD9/SASE1
    • The HiRex is fully operational
    • The Si-Mono needs work but this was de-prioritized as it is not needed for the next users

Laser

  • Full specs were reached for both the SPB and FXE beams. The laser is in the respective instrument laser hutches
  • The laser was covered in order to reduce effects of any remaining air drafts
  • Differential mode compensation is available. Common mode compensation is not
  • Work still continues on the 4 agree-upon bunch patterns. Another meeting is set up for today
  • Delay control is available through KARABO but requires ca 2 days testing

Detectors

  • For AGIPD both  for turning on power and cooling automatic procedures were implemented and tested
  • LPD was moved to Karabo 2.18. 
  • One charge injection run was done and the system operated for 2 days without interruts

Electronics

  • Currently the work that is still needed for SASE3 is being evaluated
  • Planning for the next shut down is going on

CAS

  • Currently planning next OCD period
  • Very good progress was made in SASE3
  • Working on DOOCS/KARABO integration together with DESY
  • Work on the laser is progressing
  • A. Silenzi and S. Hauff worked on the AGIPD procedures
  • Work continues on reading and writing data for the GreatEyes detector
  • As reported by the detector group, the stability of the DAQ is much improved

ITDM

  • A major problem caused the Maxwell cluster to be down for 3 days. IBM Technicians had to be called
  • In this context it became clear that the communication with the users must be optimized
  • Now the system is ok
  • The folders for the next user run are being set up next week. This was delayed due to the technical problems
  • For the experiment log books the users will now be automatically set up
  • The update of the DAQ for AGIPD is somewhat delayed due to the long time taken for the recabling
  • SPB requested 18 new cameras. This effort needs to be carefully coordinated.
