Vacuum (twiki, EDMS)
- change status to ready for beam to ECS after interventions by the CERN vacuum group (watch for date in run meeting; be available for monitoring while Didier takes the actions; make sure to go through 'evacuate' after Didier is ready)
- maintain SmsVacTool script and start it in Neon periods (running on vedcs02)
- check APDP in Neon periods (velo_user_panel)
- 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)
Motion (twiki, EDMS
- put detectors in place before/after Neon periods (see e.g. elog before, elog after)
- perform potmeter calibration: WinCC-panel, data-analysis, upload results to motion-PLC if needed (once a year! see manual and last elog)
- discussions with CERN PH-DT group on the new motion control system (Giovanna Lehmann, Xavier Pons and Sylvain Ravat; link to meeting)
Cooling (twiki, EDMS)
- be able to put CO2-pumps under gas for pump maintenance (see EDMS manuals, one for each pump)
- theory and practice: sub-cooling on input of pump, control PLC-screen, make and interprete trend plots, superheated CO2 (CO2 not cooking), preheaters, SMS tool
- if after restart, superheated CO2 (some coockie temperatures larger than normal by >=2 degrees), start preheating procedure (wikielog)
- special plots for TL-pump (monitor TL_Diffp_plus in trending tree of velo_user_panel)
- check long-term behaviour of system (best: sensor NTC temperatures; simplest: coockie temperatures) , e.g. to reduce risks of thermal runaway (if cooling becomes worse we probably loose pressure due to clogged filters; watch pt104 and pt003 in vecool)
- maintain alarm levels in the alert system (velo_user_panel)
- be standby 365, 24/7 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, on our initiative, every year, when not under Neon. (see elog) Seicar contact goes via Olivier Crespo ( Olivier.Crespo-Lopez@cern.ch ) from CERN cooling group.
- put system in correct state before/after Neon (setpoints, interlocks, see elog)
- keep track of TinyTags data and dry air flow (check that air is dry)
- order spare parts (pumps, filters) and coordinate maintenance and repair (Bart van Donk at LEWA)
Common vacuuum/motion/cooling
- participate in VELO run meeting on Tuesday morning
- check UPS systems and maintain spares (visual inspection once a year in racks downstairs; small: motion cooling; big: vacuum; spares in detector lab bought in LS1; check that leds are burning; web interface)
- maintain email lists of UPS systems (?)
- check VMC system after yearly AUG and diesel tests (make sure to read run meeting minutes; if restarts required, do vacuum system first)
- update interlock settings before/after Neon period (see elog)
- take care of storage in Bld 169
- maintain manuals pages in VELO-twiki and EDMS documents
- take care of dosimeter reading for dosimeters stored in Velo office
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 at Nikhef
Actions 2017
- Jan: refurbishment of TR pump; needs LEWA parts + Erno
- Feb 27: AUG test
- Apr 24: Beam-pipe pump down (monitor vacuum and cooling; put detector in correct position afterwards)
- After Apr 24: Chiller maintenance
