Vacuum (manuals)

  • answer questions of and perform discussions with the CERN vacuum group about the new vacuum control system (Rodrigo Ferreira, Giuseppe Bregliozzi, Paulo Gomes, Henrik Vestergard)
  • maintain SmsVacTool script and start it in Neon periods
  • check APDP in Neon periods (see manual)
  • change status to ready for beam to ECS after interventions by the CERN vacuum group

Motion

  • perform potmeter calibration: WinCC-panel, data-analysis, upload results to motion-PLC
  • discussions with CERN PH-DT group on the new motion control system (Giovanna Lehmann, Xavier Pons and Sylvain Ravat; (link to meeting)
  • put detectors in place after Neon periods

Cooling

  • be able to put CO2-pumps under gas (e.g. for pump maintenance)
  • theory and practice: sub-cooling on input of pump (?), control PLC-screen, make and interprete trend plots, superheated CO2 (?), preheaters, SMS tool
  • special plots for TL-pump (??)
  • check long-term behaviour of system, e.g. to reduce risks of thermal runaway
  • maintain alarm levels in the alert system (PLC?)
  • be standby 365, 24/5 to react when system switches to backup, or if anything else goes wrong
  • maintain telephone numbers in PLC sms tool
  • lend assistance to Seicar for chiller maintaince
  • put system in correct state before/after Neon (setpoints, interlock?)
  • keep track of TinyTags data and dry air flow
  • order spare parts and coordinate maintenance and repair

VMC (?)

  • check UPS systems and maintain spares (?)
  • maintain email lists of UPS systems (?)
  • check VMC system after yearly AUG and diesel tests (?)
  • update interlock settings before/after Neon period
  • take care of storage in Bld 169
  • maintain manuals pages in VELO-twiki and EDMS documents
  • participate in VELO run meeting on Tuesday morning


Velo upgrade

  • co-coordination of WP5: keep track of anything that relates to modules such as sensors, readout, data tapes, markers, LV- and HV-cables, components (substrates, hybrids, ...)
  • participate in module-0 meeting on Tuesday
  • take care of wafer and glass parts in clean room storage
