Subject: Status and Plans after the 9:30 meeting 

XTDs Info:

Tunnel XTD2 will be accessible this Thursday, 27.04. between 9 and 12. Dosimeter and General radiation training required. Access requests should go to T.Haas.

XTD10 will be closed starting from this Thursday, 27.04. at 12:00

Provided that the authorities give the "go ahead", DESY plans to put beam in XTD2 on Thursday's evening.

 

Karabo:

  • System running  but performance of the GUI still sluggish
  • There appears to be a resource leak. Second server will be set up tomorrow as workaround. Experts are working on it.
  • In parallel experts are working on a definitive solution
  • Deployment today on a new beckhoff device for the decodification of PLC error messages.

Vacuum:

  • Systematic tests of ion pumps started again

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 ask Natalia for acceptance test definition for PBLM
  • Motion loop will be down until 10:30 for update. An entry will be written when the loop is again up. 

SPB Tunnel components

  • The Renishaw encoders can be read and positions are reliable. An error message is coming from the encoder and is probably due to a wrong voltage level delivered to the encoder. The encoders can be operated in this condition.
  • T. Freyermuth is in contact with the encoder company tu understand the problem and work on a fix
  • The same problem also affects FXE components
  • The cameras operated at 1Hz deliver delayed images. 1/3 Hz operation (almost live mode) is OK - probably related to GUI memory issues

FXE

  • Encoders of Loop1 have the same error message as SPB - the encoder positions are reliable - local components test can go on (e.g. OGT1)
  • Encoders of loop2 are not powered - AE to investigate

 

Tasks for today:

  • Identify a fix/workaround for the GUI server resource problem
  • Deployment of a beckhoff device for the decodification of the error messages.
  • Find a solution for the Renishaw encoder problem SPB Tunnel/ FXE Loop1
  • Investigation of the FXE Loop2 encoders power
  • Continue testing of ion pumps in XTD9
  • Test of gas section interlock in XTD9

Tasks for tomorrow:

  • Setup of the second server for karabo GUI
