GAS M&O meeting 20 May 2020
Present: Beatrice, Roberto, Andrea, Patrick, Kacper, Fred, Mara, Gianluca, Fabio, Federico, Leonardo
 

 

CHECK Gas Systems

 
ALICE #2491
TOF
  • GC analysis: SF6 at 6.8%
 
ATLAS #2490
MDT
  • Reset of pressure sensors giving problem (elog #2489)
    • To check the grounding
  • P&ID test on going with Gianluca (elog #2437)
  • Problem with the reading of one flowcell: connector found with a bit of oxidation. Now cleaned and it seems working
TGC
  • On-going preparation too tart weld next week
RPC
  • Rack 62 in open mode
  • Second line of mixer we have N2 instead of iC4H10
 
CMS #2493
RPC
  • Add iC4H10 and SF6 to the mixer. Still a problem of calibration for MFCs —> need to set iC4H10 MFC at 4% to have 4.5% in IR
  • Increase flow to 400 l/h
  • Test on regulation valve (ECONEX) on-going. Next Tuesday need to move ECONEX from rack 74 to rack 83
  • Rack 80 ch 7 problem in reading: to check cables in flowcell when there is an access —> Andrea
CSC
  • MFCs calibration on-going
  • Replace Krohne in Exhaust module with a new one
  • Gas system will be re-started on Monday and distribution rack 63 must stay in stop
CF4 recovery
  • Add two MFMs in membrane module
  • Add new battery for the CF4 storage
PGS
  • Ar/H2 leak repaired
  • MFM of SF6 and iC4H10 don’t work properly. Beatrice to check with David
  • Patrick said that calibration of MFM is much time consuming than calibration of MFC (you need to add a valve in front of the MFM for regulation the flow)
 
LHCb #no elog
RICH2
  • PLC dismounted, new cabling on-going. Next week (on Tuesday) new PLC and software
  • IR modification on-going
  • There is not reading of detector pressure (DCS is also off): Patrick to check if we can have the reading of chamber pressure
  • New compressor module: no reply from Eric, so we will go for installation in the flammable room.
  • New compressor module: to find the pump for the purifier gas recuperation
RICH1
  • system stopped and restarted: we took only few ppm of air
  • To discuss what tests we want to do
SciFI
  • to check problem on 3-way valve
General
  • Federico can start leak search with new CO2 leak detector for MWPC, RICH1 and RICH2
 
 
GENERAL
  • Next week planning ok: similar to the one proposed to DT
    • FSU availability ok
  • MFC calibration campaign restarted
    • Planning discussed during the meeting
    • Planning available in indico
From previous meeting:
  • Level of PGS sometimes is > 100% —> Michal to check
