Presentation Transcript

  1. Test bench for digital sensor • New Philips Digital Light Sensor • Outer dimensions 32.6*32.6mm2 • 8*8 pixel array • Pixel pitch 4*4mm2 • Pixel active Area 3.8*3.3mm2 T. Schneider

  2. 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) T. Schneider

  3. 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 T. Schneider

  4. 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 T. Schneider

  5. 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 T. Schneider

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

  7. 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 T. Schneider

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

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

  10. 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 Lysoand WLS • Components will be kept in place on both ends, fixed • to the mechanics T. Schneider

  11. Test bench for digital sensor Ideas? Proposals Discussion END! T. Schneider
