GAS M&O meeting 19 August 2019

Present: Beatrice, Kacper, Roberto, Patrick, Andrea, LPh, Gianluca, Sabino, Fabio, Federico, Leonardo

Indico: https://indico.cern.ch/event/840853/

 

ALICE #no elog

  • MTR
    • Dummy chamber: to ask to Arturo for manpower to install the pipes
  • TPC
    • To check with Fred for filters and distribution rack to put in place

 

ATLAS #1930

  • New o-rings ordered and under aging-test: results on week 34
    • It looks ok for VITON and some aging for EPLF
  • TRT
    • Exhaust in the distribution modification to finish this week
  • MDT
    • Rack 68 (ch 17): one channel is keeping going to zero —> try to change the ELMB

 

CMS #no elog

  • RPC
    • OFF
  • DT
    • ELMB changed for the ELMB++ in rack 65 on Friday for a test —> Michal to give a summary
      • In general: before doing test in system: discuss internally
    • Pressure sensor on filter pump modified by adding 1/8 pipe as impedance: not enough, still fluctuation —> to increase the length of the pipe —> Andrea
  • CSC
    • Warning to set-up —> Beatrice/Michal/Roberto
    • To check and correct level of oil in bubblers of distribution
    • To close distribution rack with panels
    • Webmass is giving some error but everything is working fine
  • GEM
    • Missing pressure sensor in distribution on output in WinCC-OA —> Michal to ask to Marc to add
    • There is not pressure sensor on chamber —> to take out in WinCC-OA
    • Remove bubblers in distribution in WinCC-OA and add safety valves —> Beatrice to provide P&DI to Michal

 

LHCb #no elog

Reminder:

  • MWPC in run with Ar/CO2
    • Rack 64 —> to investigate

 

PIQUET

  • LHCb RICH2 stop due to storm: Fred re-started

 

GENERAL

  • Leonardo presented first drawings about the addition of filters for the purifiers of ATLAS
    • Missing pressure sensors and rotameter —> to add
    • Try to have the same configuration for CMS RPC
  • Kacper shows PID configuration for MFCs dismounted
    • To understand difference between PID of SCADA and internal of MFC —> Michal/Sabino
    • To check with Geraldine —> Beatrice/Michal
  • Standard Maintenance:
    • Add a marker to see the level of oil in all bubblers
    • To do a check of chassis status for oil contamination and to add a protection for chassis
