Tunnel Open.

Mirrors:

Status:

• Vacuum on M2 should be good enough to switch on ion pumps
• Surveying work going on 

Vacuum Loop:

Status:

• Several vacuum sections successfully tested in XTD9 yesterday
• Tests need to proceed in XTD2 today
• The protection switch on the ion pumps cannot be actuated remotely 
• Loop needs an update for the XGM
• XGM was in the vacuum interlock overnight. Will be taken out during the day but should be put back at the end of the day
• Interlock of High Voltage with vacuum in XGM not working yet
• V0 valve needs to be exercised in collaboration with DESY 

EPS Loop:

Status:

• The terminal exchanged for the FEL imager was not the broken one. Another terminal needs to be exchanged today
• The MCP needs to be moved out of the beam manually. This will be checked using the EPS switch. For this the EPS loop is needed

Motion Loop:

Status:

• An improved fix for the motors not stopping was deployed yesterday
• The loop needs to be reconfigured to replace the SRA motors 
• One broken motor was exchanged on the mirror chambers and needs to be tested

Imagers

Status:

• All motion tests in XTD2 done. Now continue in XTD9
• Photonics camera driver still not working but not critical for tunnel closure (there is also a workaround by the name of ebus player)
• EPS switch on FEL imager needs testing  after terminal replacement

Karabo:

Status:

• New version with TCP was deployed. Experience overnight is good

Tasks for today:

Note: Loop reconfiguration and updates of Karabo to be done in the morning. Testing can resume after lunch. Status updates should please be recorded in the log

• Reconfigure vacuum, motion loop (updates for XGM interlock, SRA motors)
• Replace broken terminal in EPS loop for FEL imager 
• Move MCP out of the beam manually and check using EPS
• Continue systematic test of the vacuum components (J. Eidam, V. Bondar)
• Test EPS switch on FEL imager after terminal exchange (A. Koch and W. Ehsan)
• Monitor stability and responsiveness of GUI Server and Log Servers (A. Silenzi)
• Set up monitoring of temperatures and pressures overnight (A. Silenzi)
• Test V0 and absorber

Tasks for tomorrow:

• Tunnels closed
• All loops should run stable
• No or only minimal interference with Karabo
• Continue tests from remote and check stability and robustness of systems

Other topics

• Tunnels open over the Easter weekend and also during the day on Tuesday 18 April
• There will be one more standup 09:30 meeting tomorrow (Wednesday)
• There will be a SASE Readiness Meeting at 09:00 on Thursday
