cross talk measurements
Setup: - scintillator sheets number from bottom to top in sensor image: 9, 8, 22, 26 + other sheet as fillers - CMOS ISDI Image sensor. Sensor was allowed to heat up for an hour before measurements - Optical fibre used with optical gel to couple LED to scintillator sheets
Aim: Measure Cross talk between sheets Plan is to insert light into the two middle sheets of the 4 main sheets and measure the light output with the CMOS sensor. Also take background images at regular intervals.
