TestBeamOct2019 @ DESY




This section will summarize the main documents, informations and results of the October/November 2019 testbeam.
A fiber based telescope was installed in the testbeam area TB22.

  • The layout is presented below.

Data access

The data can be found on:

Run plan

  1. Over voltage scans 1: Runs with 500k and 50k trigers (OV=2,2.5,...,6V) @center
  2. Over voltage scans 2: Runs with 50k trigers (OV=2,2.5,...,6V) @positions 1-2-3-4 (see drawing)
  3. X and Y scans: 50 k triggers
  4. Lead runs 1: Placement of 1,2,3,4 lead plates in front of the entrance window
  5. X and Y scans (after new calibration)
  6. Over voltage scans 3: 1M triggers!
  7. Lead runs 2: Placement of 1,2,3,4,5,6 lead plates btw X2 and Y3
1. Over votage scans 1
