XTDs Info:

Tunnel XTD2/4 will be accessible today until 1500. Dosimeter and General radiation training required. 

XTD10 will be closed starting this afternoon

Vacuum:

• DPS with interlocks was tested successfully yesterday evening but...
• ... Complete failure of gas sections in both XTD and XTD9 some time tonight. Valves were closed and turbo pumps were off. Reason is still being investigated
•  
• Systematic tests of ion pumps in XTD9 done for 3 vacuum sections. Currently only the pumps are tested. Tests of the interlock will follow
   

Karabo:

• The problem with the GUI server has unfortunately not re-occured. Hence it can currently not be debugged.
• Second GUI server is available for fall back
• Remote reset of TP controllers has been implemented and will be deployed in the next release

PLC

• A problem was found in the MC2 library affecting the ELMO controller.  This only affected the systems deployed in the tunnel. 
• The non-linear behaviour of the PBLM motors was reproduced independently of PLC and KARABO. Suggestion: Could this happen when the motor has to work against vacuum pressure? Evidence: It does not occur in the lab (no vacuum!)
• A video session with the manufacturer is schedule for next week to look at the problem

PBLM/Motion Loop: 

• There is a resource problem when trying to read out the cameras. This problem will be reconsidered once the general issue with the GUI server is solved.
• ASilenzi will discuss offilen with Natalia the acceptance test definition for PBLM
• List of errors and relative solution concerning ELMO absolute encoder implementation being worked out by AE/CAS

EPS

• Logic of EPS was agreed between AE and H. Sinn:
  • Currently only covers devices up to XS3
  • Vacuum ok requires all valves to be out of the way
  • Any screen down  forces single bunch mode
  • All imagers in safe position allows full beam mode
• Meeting next week @ DESY to discuss technical details with MPS group

SPB Tunnel components

• Renishaw encoder can be read out reliably after fix for error signal line
• SPB would like to work on the pulse picker next and is waiting for it to be integrated

FXE

• FXE guys would like to help with tests of Hard X-Ray Mono 

Tasks for today:

• Perform various maintenance tasks in XTD2, e. g. integrate CRLs, exchange photo tubes, exchange gases
• Investigate why gas sections switched off yesterday
• Continue test of vacuum components in XTD9
