Regular datataking (continued as in P12

Taken every night, if availability of staff (at least 1 shifter + 1 camera shifter + Commissioning Leader) and meteorological conditions (Watch humidity and temperature limits of camera!) allow.

Note all runs in eLog and RunCatalog!

• Prepare night data taking (last point), if applicable
  • Unlock telescope
  • Focus mirrors at sunset (not before!)

• HV off, shutter closed
  • Pedestal 1kHz constant frequency (TIB-triggered): 100k events
  • Pedestal 1kHz random (DRAGON-triggered): 100k events

• HV on (shutter still closed)
  • Pedestal 1kHz constant frequency (TIB-triggered): 100k events
  • Pedestal 1kHz random (DRAGON-triggered): 100k events

• Switch on calibration laser, if to be used later
• Park out telescope (earliest after sunset)
• HV on, shutter open
• Move to dark spot.
  • Open the shutter in park position (ZA limit 60°!), but then move to dark spot (to avoid passing cars' lights).
  • RA=211.08°/Dec=+29.52° is a good candidate for the dark spot; you may have others.
  • Pedestal 1kHz constant frequency (TIB-triggered): 100k events
  • Pedestal 1kHz random (DRAGON-triggered): 100k events
  • Calibration pulses (L1-triggered) 1kHz constant frequency

• Pointing and data taking
  • Select a target (ask experts, or chose a reasonably active source)
  • Kill noisy pixels
  • Taka data for max. 1 hours

• Dont' forget the proper shutdown sequence of all elements!

Planned actions

Monday July 8th

• BP tests with Gustavo/Carlos?
  • test with TP and without HV where we perform the initialization, read the settings coarse and fine delay setting from the BP, using TP measure the up+down time, and repeat the cycle again, two or three times?

• CaCo start-up checks, CaCo recovery, CaCo - EVB - TIB comm. (Mitsunari) ?
