Minutes for UCL Proton Calorimetry Meeting, 29th March 2017 (D17, Physics & Astronomy, UCL)

Present

Simon Jolly, Laurent Kelleter

LK:

• Looking at dose build-up effect in proton therapy and secondary particles.
  • 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.
