Minutes for UCL Proton Calorimetry Meetings, 6th May (Everyone is working from home)

Laurent Kelleter, Saad Shaikh, Raffaella radogna

Set up parallel GEANT4 project from a basic example to rebuild Laurent's simulation from scratch.
Analysed SOBP data from HIT 12th April 2019, was able to successfully fit data but realised that data acquisition missed some of the beam delivery. Shown in this this presentation.
- Moved away from current binned fitting implementation, in favour of ROOT's fitting option "I" and using smooth QB function to fit data. Fit speed roughly the same. Note: SOBP fit fails with this option, but fit results are fine without it. SOBP fit takes ~10mins with original binned fit implementation, takes 10s with smooth QB fit.
Started research into FPGA programming:
- Some basic theory of logic gates, LUTs, Flip-flops etc.
- Ran hardware-version of 'Hello World' on Zybo: program board to blink an LED.
Laurent will get in touch with Stephan Brons about HIT FLUKA curves for He, C and O beams.
Laurent suggested that analysis of x-axis profile of beam is possible with CMOS sensor – could be worth investigating.
