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 (running on vedcs02)
check APDP in Neon periods (velo_user_panel)
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)

perform potmeter calibration: WinCC-panel, data-analysis, upload results to motion-PLC (once a year! see manual)
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 before/after Neon periods (see e.g. elog before, elog after)

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 (?), preheaters, SMS tool
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 (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 (phone, e-mail?)
put system in correct state before/after Neon (setpoints, interlock, see elog)
keep track of TinyTags data and dry air flow
order spare parts and coordinate maintenance and repair (how?)

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
