Irradiation Logbook

Measurement points (or rather zones)

Edit pictures to define new points, if needed.

Definition of measurement zones. The maximum inside the zone has typically be searched to record the measurement.

• LST1 area
  • CC1 - at the main entrance of the commissioning container
  • CC2 - bushes towards fact (measure from inside LST area)

• MAGIC counting house
  • CH1 - parking area (and bushes towards road)
  • CH2 - left garage door
  • CH3 - right garage door
  • CH4 - "sombrero del enano" house (typically above the windows)
  • CH5 - below the windows (corner to entrance)
  • CH6 - bushes between MAGIC and FACT

• FACT area (and close surroundings)
  • FC1 - FACT container
  • FC2 - Fence, bright spots

Measurements

Carried out with either the PIN diode device provided by Thomas/MPIM or (mostly) the lumimetre borrowed from IAC.

For the Pointing direction, we have used:

• sun = measurement with optimal orientation directly to the sun
• opt = measurement of maximal irradiation of reflected (mirror) and direct sun light.

Timestamps are in UTC!
