• BGV at EOS class
  • Temperature / Currents plotting
  • Info from Didier for gas pressure
  • SiPMs currents vs Time
  • WinCC chron job - SiPMs current & tempreatures

[13 / 06 / 2016] BL Students Meeting

  • Big discussion on BGV, especially for future plans

[15 / 06 / 2016] BGV Meeting

  • For me to contact Didier for the gas pressure non-linearity.
  • Also to check the remote control of the relay from the chiller
    • possibility of accessing with ssh tunneling from bgvgw, or by rdesktop login to OPC machine and then browse to the relay.
  • TELL1-07 - no conclusion on what is the issue.
  • Finish the BGVatEOS class.
  • Presentation from Olivier for test beam
  • Cooling installation done - still to remake tent, do the leakage tests.

  • Olivier about SiPMs bias supply
    • No more than 4.5V other the breakdown voltage -> SiPMs no stable anymore - fluctuation, correlations etc are messed up.
    • This should be also configured according to the temperature
    • I need more info here: find characterization or something like this.
    • Mariana says Axel has done this work and sent the required voltages for 20 C
