2. 7 october 20112T. Schneider Test bench for digital sensor Material available : (Leftover of 2 module assembly) 8 Lyso crystals 3*3*100mm³ one end Al coated WLS strips 3*1*40mm³ (~30) WLS strips 4*1*40mm³ (~20)

3. 7 october 20113T. Schneider Test bench for digital sensor 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

4. 7 october 20114T. Schneider Test bench for digital sensor 4 row arrangement of 2*8pixels on the digital sensor + 1mm WLS spacing => Limit in one dimension to not more than2 crystals

5. 7 october 20115T. Schneider Test bench for digital sensor Preliminary 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

6. 7 october 20116T. Schneider Test bench for digital sensor 2*2 Lyso Mechanics 4*2 WLS Option: double sided Lyso read out 32 pin connector for WLS readout 32 pin connector for Lyso readout Lyso positioning WLS positioning

7. 7 october 20117T. Schneider 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

8. 7 october 20118T. Schneider Test bench for digital sensor Module can be turned and position to our needs Read out connectors stay accessible

9. 7 october 20119T. Schneider Test bench for digital sensor 2*2 arrangement of Lyso crystals 4*2 arrangement of WLS Separation needed between Lyso, WLS  Lyso, WLS ?

10. 7 october 201110T. Schneider Test bench for digital sensor Simple 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
