P13 (8.7.2019 - 22.7.2019)

• Commissioning Shift Period: 13
• Dates: 8.7.2019 - 22.7.2019

• Commissioning Shift Leader: Moritz Hütten
• Commissioning Shifters / Experts:
  • Drive: shift crew
  • Camera: Taka (until 6.7.), Yokiho Kobayashi (until 13.7.), Mitsunari (from 27.6.)
  • AMC / Mirrors: shift crew, Tomohiro (from 15.7.), Satoshi (from 17.7.)
  • Former CSL: Dirk Hoffmann (until 7.7.)
  • Others:
• Shifter: Noah Biederbeck (until 13.7.)

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.
  • MAGICs Dark Patch 05 at RA=256.25° / Dec=38.33°
  • 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

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

Night: Sky data

Tuesday July 9th

Schneider people repair broken fans in IT container (canceled because of incident)

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?

Night: drive tests with Ino (23:30 - 0:15)

Wednesday July 10th

9-11: Casana finishes work in CC (floor of server compartment)

Further investigate TIB failure problem (day and evening)

Night: Drive tests/reproduce TIB failure?

Thursday July 11th

Javier Aragunde on site with José Ferraz company for LST-1 LPS

Continue work on TIB failure

Search for dark patches with constraint of optimal moon distance

Night: Take data with HV and bright moonlight

Friday July 12th

Night: Dark spot observation (with HV?) at moonlight

Saturday July 13th

no operations (weekend)

Sunday July 14th

no operations (weekend)

Monday July 15th

11a.m.: Meeting with project manager in commissioning container

Control EVBv3 over CaCo

Night: take pedestals with shutter open (HV at bright moonlight?). Star tracking for PSF studies

Tuesday July 16th

• shutdown of energy storage container during whole day (No electricity in the telescope, Commissioning container and IT container will not be affected.)

Wednesday July 17th

• shutdown of energy storage container during whole day (No electricity in the telescope, Commissioning container and IT container will not be affected.)
