LED injected light measurements
Setup: - scintillator sheets number from top to bottom in vice/enclosure sequence: 51, 31, 50, 52, 34, 44, 53, 47, 33, 54, 46, 42, 55, 45, 38, 36, 43, 32, 48, 41, 8, 39, 40, 37, 35, 49, 9 + other sheet as fillers - 16 Photodiodes covering the sheets sequence 42, 55, 45, 38, 36, 43, 32, 48, 41, 8, 39, 40, 37, 35, 49, 9. - Optical fibres used to inject UV light into scintillator sheets provided with the fibre entrance (sheets 51, 52, 53, 54, 55 have no light injection) - painted side of the stack with fibre holes on top, PDs placed 90deg w.r.t. the injection side.
Aim: Take large statistics runs with fixed integration time and all possible Full Scale modes to caracterise photodiodes.
