How can the components be arranged on the digital sensor? …and how many?
Need more that 1mm space in-between the crystals in one dimension in order to fit the WLS

Test bench for digital sensorPreliminary idea for mechanical setup :•Mechanical housing (material to be decided: Alu/plastic) to keep sensor boards (2-3) and components in place•Positioning of 4 Lyso crystals and 8 WLS•One or double sided readout for crystals possible

2*2 Lyso Mechanics
4*2 WLS
Option: double sided Lyso read out32 pin connector
for WLS readout
32 pin connector for Lyso readout
Lyso positioning

Test bench for digital sensor
•Digital sensor card is fixed in the mechanics•Optical contact is foreseen via optical grease•Components will be pushed slightly from the other side to guarantee good optical contact

Test bench for digital sensor
•Module can be turned and position to our needs•Read out connectors stay accessible

Test bench for digital sensor
•2*2 arrangement of Lyso crystals•4*2 arrangement of WLS•Separation needed between Lyso, WLS Lyso, WLS ?

Test bench for digital sensorSimple solution for component positioning :
•2 thin plastic plates with precise slit machining arranged in 90deg will guarantee the x/y positioning of Lyso and WLS•Components will be kept in place on both ends, fixed to the mechanics
