  • Black Box: done!
       Size: roughly 1m x 1m x 1m
  • LED related issues: done!
     LED system specs:
           3 pulsed LED and 1 continuous LED
           BLUE light, 470nm(2.637ev), 20mA current
           nominal luminous intensity: 232mcd (232*1e-3*4pi/62)*6.2415093433e+18/2.637 = 1.1e+17 photon/s

Test plan

  • 1.Calibrate ADC channels
     Using a generator to produce a well known amplitude signal to calibrate ADC: ADC counts <-> Charge
     WaveTek model 80 from 3He lab
  • 2.Gain VS Voltage scan (H8500: -350V <---> -1100V)
     Relative gain VS voltage curve:
        Sinle channel measurement is enough
        Setup: LED -> fiber -> Any single pixel -> Readout
        Or no fiber: LED -> Any single pixel -> Readout
     Absolute gain calibration:
        Yi has a photon calibration tube, I can use it to calibrate the absolute gain.
  • 3.Determine a low gain range for SoLID preshower
     5E3
  • 4.Uniformity measurement at low gain case
     No fiber is needed in this test, open cathode
     Challenge: A uniform distributed light should be produced -> need to figure out,Yi has experience on this
     Setup: Uniform light -> open cathode -> 64 channels readout -> uniformity
  • 5.Cross talk measurement
     Size of a Pixel: 5.8mm X 5.8mm
     Setup: LED -> fiber -> pixel -> readout(surrounded pixels)
     As suggested by Yi, do a position dependent cross-talk study ---> scan fiber within a pixel to see the cross-talk effect
  • 6.Test with Pre-shower tile

Test results and weekly meeting
