  • 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.
