Minutes for UCL Proton Calorimetry Meetings, 17th February (D17, Physics & Astronomy, UCL)

Present

Simon Jolly, Laurent Kelleter, Saad Shaikh, Raffaella radogna

Saad Shaikh

  • he is able to fit real data using Laurent's code
    • all of the steps are included, quenched bragg fit and reconstructed curve. comparison with simulated distrivution is also included.
  • the range is always slightly underestimated
    • fitting simulated data, a small underestimation comes from the model
    • fitting real data, the underestimation is consistent with uncertainties
  • he tried data for measuring range withour PMMA absorbers and data with absorbers to double check the WE thickness of the absorber
  • the analysis includes Bkg subtraction and calibration
  • comparison of run 47 30mm vs 52 21 mm and dependence with beam size
    • the smaller beam has higher light output, but the difference in light output compensates at the Bragg peak.
    • will plot spot size intermediate steps to check the consistency of the measurements.
  • started implementing more object oriented way of implementing data.
  • he is interested in running geant4 simulations in the near future

Raffaella Radogna

  • busy with grant application
  • performed hardware test to optimise the design of the electronic board with Bernard.
    • the best option is having 2.86 mm pitch for best coupling PDs array and scintillator sheets
  • will double check with knoledge exchange the information provided by Laura


Laurent Kelleter

  • cross talk measurements performed last week
    • LED with optical fibers to inject light
    • he will perform the analysis to quantify it.
  • final version of the quenched bragg paper for submission
  • will start sending his thesis to Simon for corrections
