Test Setups in preparation - The Lasertestunderstand the signal response

• Calibrate the signal response

  • measure each pad for 1, 2, 5, 10 MIP
  • find dead channels
  • create Database

• Stability test by source

  • noise
  • MIP signal (12h@2Hz = 28 hits/pad for 2 T1 = 84 hits/pad for 4 T5
  • detector current

• 1064nm laser
  

• Sr90 source
  

• Idet
  

• Problems: absolute laser calibration,
  

• time stability, very precise X-Y stage

• support - optics, cooling, test time, ...
