The MicroTCA crate used in rack 3.4 (XTD10) has been replaced. The system is up and running. Timing information is properly distributed from this system to the MicroTCA system in rack 3.2 and XGMXTD10.

since tunnel access is now possible 

The Vacuum Controls Commissioning Task Force initially helped to get the vacuum components extending from the gate valve at 2678 m to the gate valve at 2730 m in XTD2. This comprised the valves and pumps and the associated vacuum interlock logic. The necessary components were all installed and locally tested. As the next step the PLC firmware for the control of these devices was generated including the interlock logic. Finally the system was connected to version 1.47 of Karabo, which was able to monitor and control all components. A live demonstration is currently still outstanding.

As the next step the vacuum section considered should be extended upstream to include all components up to the gate valve at 2630m. In addition to vacuum components this should include the installed photon beam line components. The goal is to include all these systems into one continuous vacuum, commission all systems locally, generate the PLC firmware, implement the required vacuum interlocks, monitor the state of the system remotely via the PLC command line interface and eventually connect to Karabo and monitor and control the system via Karabo remotely using the consolidated version 2.0. While this commissioning effort is going on, development should occur on three days during the week (Mo-Wed) while the system should be operated continuously during the remaining time, thus also testing long-term stability. This should be achieved by the end of 2016.

 In KW17 there will be NO maintenance day on Tuesday (25.04.) 

 
On Monday (24.04.) morning up to about 11:00 we will have the TÜV approval of CS8. During that time 
 NO access of "other people" to the XTL tunnel is possible. After the TÜV approval 
 up to 13:00 there will be the possibility for URGENT access to the XTL. Access requests 
 have to written to the logbook/access requests entry. 
 
The tunnel XTL/XTIN will stay in interlock, access will be possible by ZZ only. 
 
The northern branch XTD2->XS3->XTD4->XDU2 will stay closed, in order not to interrupt the 
 magnet commissioning. 
 
This elogbook entry was sent to following experts: 
xfel-opl@desy.de RC mailing list  

The MPS comm for SASE 2 and FXE were tested and the only remaining part is to test the SPB to MPS changes. Tomorrow morning a  timeslot will be agreed between AE and SPB.

Dear all, Vacuum and Motion loops are running again.

Thank you,

Dear all,

find here the foreseen loop status for KW12. The schedule could change. All changes will be notified by entries in the logbook.
