Tunnel Status (T. Haas):

• Tunnels XTD2/4/10 were interlocked yesterday afternoon
• Beam is already going through the T2 and T4 beam lines to T4D
• XTD9 remains open until approximately 15 May

Vacuum (J. Eidam, R. Villanueva):

• The interlock in the gas section was tested successfully in XTD9. The interlock does currently not include the gas injection. This still needs setting up and testing
• Systematic testing of ion pumps and interlocks is ongoing in XTD9 but needs to continue next week
• The system generally works reliably
• However, there was an incident this week in which the gas sections in XTD2 and XTD9 went completely off. The reason is still not understood

Mirrors and PBLMs (H. Sinn):

• All three mirrors in the SASE1 beam line in XTD2/9 are installed and pumped
• N. Gerassimova installed PMTs in XTD2 yesterday and set up the cameras of the PBLMs
• The problem with injected properties disappearing was identified on the Karabo side and fixed. The fix still needs to be deployed
• The motors of the PBLMs are still not functioning completely. 
• The read out rate of the cameras is ok (of the order of 10Hz or better)

Imagers (A. Koch):

• Imagers in XTD2 and XTD9 are ready for beam
• Work continues on improvements
• Read out rate is ok, but the latency is sometimes high and needs to be unterstood

XGM (J. Grünert):

• The gas on the XGM in XTD2 was changed at the request of K. Tiedtke from Ar to Ne
• Tests were done with the remote control of the gas system. This is now fully functional
• The HV/Vacuum interlock is not operational yet
• Otherwise the XGM is ready accept beam. Next week software tests should be performed with the readout

FXE (A. Galler):

• Currently commissioning loop 1. There is still a problem reading out encoders. It appears that this is a firmware issue. TF is working on this.

SPB (B Weinhausen):

• Currently commissioning the SPB tunnel components. The encoders have the same problem as the one reported by FXE
• I broken terminal required changing

PLC (T. Freyermuth):

• CRL in XTD2 was integrated into the PLC motion loop yesterday during the access.
• A first version of the EPS logic was agreed upon and implemented. Details to be discussed again with DESY next week

Karabo (A. Silenzi):

• ITDM provided an additional control server
• A redeployment of Karabo is necessary and will be done later today (users will need to re-connect afterwards) 
• The problems previously observed with the GUI server have not re-occured. 

Plans for next week:

• Consolidate vacuum in XTD2 so that V0 can be reliably opened when first beam should be transported
• Finish work in XTD2, in particular PBLMs and instrument components
• Finish systematic tests of ion pumps in XTD2
• Deploy fix for Renishaw encoders in firmware

Other topics:

• We continue the 09:30 meetings next week until further notice
