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)

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)

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 (wiki elog)
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)

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, vac 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
participate in VELO run meeting on Tuesday morning
take care of dosimeter reading

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

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
