Revision as of 13:44, 21 April 2021

Simon Jolly, Raffaella Radogna, 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.
