SciFi Tracker Testbeam November 2016

Instructions for Shifters

Shift List

TBA

Aim of the Testbeam

  • Single hit efficiency vs. light yield
  • Irradiation studies
  • Angular scans (for comparison with simulation)

  • Change beam from $\pi^{\pm}$ to $\mu$
  • Measure at mirror at 3.00, 2.90, 2.10 and 2.00
  • Switch SiPM arrays on 2016 module from 2014 to 2015 Hamamatsu.
  • Measure again at same points as before

Angular Scans:

  • TBA

Fibre Mats/Modules

  • 5-layer module irradiated in the LHC tunnel, 2014 fibres (2.5m)
  • Irradiated 6-layer module from Nov '15 testbeam, 2015 fibres (2.424m)
  • DUT: Irradiated 6-layer module, 2016 fibres (2.424m)

Read-out

  • 2014 and 2015 fibre mats read out with 2014 Hamamatsu SiPM arrays
  • 2016 module read out with 2015 Hamamatsu SiPM arrays
Module SiPM LED bar LED Driver Uplink (upper) Uplink (lower)
2015 2015 ? ? 1 2
2016 (DUT) 2014 / 2015 ? ? 3 4
2014 2014 ? ? 5 6

Swapped the

Setup

  • DUT (2016) sandwiched between 2015 (beam side) and 2014 module
  • 2015 module: irradiated side up
  • 2016 module: irradiated side down

Position Definition

  • Modules mounted on two axes linear table
  • Vertical adjustment:
    • max. distance: 340mm
    • topmost position: 0.45 (on remote)
    • bottommost position: 4.55 (on remote)
    • position 3.30 --> beam hits upper edge of modules
    • 'up' on remote "moves" beam downwards on modules
  • Horizontal adjustment:
    • max. distance: 380mm
    • leftmost position: 0.45 (on remote, "Jura side")
    • rightmost position: 4.08 (on remote)
    • position 0.45 --> beam hits mirrored end of modules
    • 'left' on remote "moves" beam towards mirror, 'right' towards SiPMs
