Beam tests of the UCL plastic scintillator range calorimeter.

The tests were carried out with an energy of 36 MeV. A Bragg Peak measurement was carried out to confirm the exact beam energy.
Collimators used: 2 mm and 20 mm diameter.
The average background value per pixel for the sensor is ~ 2500. The sensor pixel dimensions are 1030 x 1536.
6 x 3 mm scintillator sheets were used. The scintillator stack was set up in the following order, starting with the first sheet facing the beam:
- 31, 32, 33, 34, 35, 48
The scintillator stack was coupled to the sensor using optical gel.
The dose received (as shown on the monitor in the control room) during the full day of measurements was:
- With a 2 mm collimator: 746.9 uC
- With a 20 mm collimator: 417.7 uC
- With a 2 mm collimator + 3 mm of PMMA: 251.5 uC
