Commissioning Shift P13

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.)

Night: Check with Carlos Diaz setting of SIS plate with OPCUA. Taking pedestal data

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.)

EVB and rate scan tests

Night: Pedestals; PSF camera and pointing tests by Tomo and Satoshi

Thursday July 18th

Evaluation of yesterday's tests/images

Introduction for subsequent CL

Night: Pedestals (again with HV?), star tracking for pointing offset tests

Friday July 19th

Night: Pedestals (again with HV?), correct putative error from last night; continue tracking of Vega for pointing offset tests

Saturday July 20th

no operations (weekend)

Sunday July 21th

no operations (weekend)
