Simon Jolly, Raffaella Radogna, Saad Shaikh

Saad Shaikh

  • Package arrived safely at CosyLab and Marko is able to run DAQ with loaned Nexys Video and Raspberry Pi.
  • Conducted beam test at UCLH, experimental notes found here.
  • Started analysis on UCLH data, discussed first findings in [ this presentation].
    • Will add frame rate and averaging rate as seperate arguments for averaged replay script.
    • Will add measurement number and number of measurements to view as arguments for stepped replay script.
    • Need to tweak shoot-through averaging to take into account absolute light difference in shoot-throughs.
    • Need to reduce effects of pulsing by taking average of each acquisition to divide photodiode values with. This should reduce standard deviation artificially.
    • Need to consolidate UCLH reference curves for comparison.
  • Will meet Simon tomorrow at UCL to:
    • Measure full scintillator stack thickness.
    • Note down scintillator sheet order.
    • Measure photodiode cross-talk using LED (without dismantling setup).
    • Dark measurements at different FSR in lab/office (with CMOS sensor running?).
    • Potentially discuss scintillator reflection with Derek.
