Minutes for UCL Proton Calorimetry Meeting, 22nd March 2017 (D17, Physics & Astronomy, UCL)

Present

Simon Jolly, Ruben Saakyan, Laurent Kelleter, Adam Knoetze, Andreas Christou

MSci projects final deadline: Monday 27th March.

LK:

  • Looking at dose build-up effect in proton therapy.
    • Dose increases at start of X-ray depth dose curve due to short-range electron shower.
    • Effect present for protons but much smaller.
  • Managed to reproduce results over 10mm from Benjamin Tham's previous simulations.
  • Build-up effect present for both electrons and secondary hadrons, but build-up much shorter for electron shower (~1mm).
  • Will run simulations for 100MeV and 200MeV with higher statistics.

AK:

  • Issues with integrating waveforms: SJ suggests inverting waveform and subtracting from baseline value.
  • Will speak to ABF regarding differences in results from scope data.
