General

• After discussion between XFEL Vacuum (J. Eidam) and DESY XFEL Run Coor (Matthias Scholz) it is agreed that XTD10 will only be closed on Thursday and that XFEL will search the tunnel between 15:00 and 17:00. (This information became available only after the meeting)
• This gives some extra time to finish activities in XTD10

Instruments

• FXE
  • Currently A. Parenti and FXE are hunting a spurious data loss in Gotthards
  • Otherwise the software is surprisingly stable
• SPB
  • Slow progress towards getting the Detector going again
  • The task to ease the acquistion needs help from the DESY developers

Tunnels

• XTD10:
  • A lot of progress was made by the team working in XTD10: Thank you very much!
  • The complete tunnel is under vacuum
  • Also the missing pieces between XGM/MCP and the rest were inserted 
  • Cleanup is done
  • Denis and Raul are still working on local tests of the gas attenuator system
  • Testing is somewhat slowed down because the GUI client no longer allows active manipulation of components at the moment. So the ikarabo interface is used
  • Work also continues on getting the mov1 loop going
  • Local tests are done on all imgers except on the exit slit imager
• XTD9
  • ​The FXE Mono is not finished. It needs a restart of the motion loop
  • AE will check when this is possible, but there are a lot of constraints from users and from resources
  • Since there has been a change in the interlock system, SPB needs to be in place when the shutter to XTD9 is opened. There is a risk of triggering the interlock and shutting down the machine.

AE

• Almost everything that was planned could be achieved in XTD10
• Some of the remaining work can be finished when the tunnel is closed.
  • Work is going on to finish the controls
• Even the interface to MPS that was originally not foreseen is now available

CAS

• The workaround that allows to modify parameters even though the protection does not allow this, is now in place. This should help with the trouble observed by the Vacuum Group.
• A new bug in the PLC was observed in this context. Changing a parameter whose name has changed leads to a crash. 

ITDM

• Currently the MAXWELL cluster is unavailable.  This is a serious software/hardware issued. The manufacturer is actually on site to fix the issue today
