Tunnel Closed until approx 1300, Open over the Easter Weekend until Tuesday 1500.

Vacuum:

• All valves and pumps in XTD2 are working and can be operated remotely
• The vacuum system including DPS and XGM is interlocked. Interlocks have been tested and are working properly
• The fast valve and the absorber at the interface to the electron beam vacuum are working and interlocked. The communication with DESY has been successfully tested
• Some issue exist when switching turbo pumps on/off in Karabo. Then erratic behaviour is observed. Doing the same remotely communicating via TCP directly works ok
• More testing needs to be done in XTD9

Mirrors, PBLMs, SRA, Attenuator

• M1 and M2 are installed and under vacuum. M3 will be installed after easter
• 3 out of 5 motors can be operated in M1 and M2. The mirrors have been moved into a safe position
• PBLM motors (ELMO driver) can be operated (started and stopped) but operation is still problematic (motors stop in wrong position, movement not linear)
• On the SRA the connection to two motors is interchanged
• On the attenuator certain motors occasionally get stuck
• Slits have been moved out so the beam line is safe for first operation

Imagers:

•  
• All imagers tested, motors and cameras, motion loop, EPS loop, for 3 imagers XTD2, and 3 imagers XTD9.
• All blocking issues concerning tunnel closure solved.
• Some remaining points that can be treated remotely: Trigger, software delays, others.
• The Photonics Camera driver is now working in Karabo.
• Cameras can currently be read out at 3 Hz which is too slow but ok for first beam commissioning

XGM:

•  
• XGM inserted into vacuum loop and interlock (in XTD2 and XTD9)
•  
• Grounding completed in XTD2+XTD9 (power cycle of rack was needed)
• Gases ready to be used in XTD2
• XGM @ XTD2 ready for beam         (need DOOCS middle-layer servers activated) 

FXE

• Testing finished for all devices in loop1
• Now waiting for loops 2 and beyond
•  

SPB

• SPB tunnel loop deployed. Testing can start next week
• For the Optics hutch some Beckhoff crates are still missing 
•  

PLC

• Fixes to MC2 library (ELMO and TECHNOSOFT motors) will deployed next week and then tested in XTD9
• FXE loop 2 was modified and loops 3&4 are deployed
• SPB loop 1 to be deployed today. Working on loop 2

KARABO

• Slow response appears to be solved
• There are other not so severe bugs on the backlog
• Currently all high priority components are supported
• No requires cleanup and day-one component list
• Monitor stability and robustness

Tasks for today:

Note: All loops should be left running and no changes to Karabo.

• Fix the issue with the disconnected vacuum loop after tunnel reopens

Tasks for the weekend:

• Relax and look for Easter Eggs
• AE and CAS will provide contacts on a good will/best effort basis in case an intervention should be necessary
