Proton Calorimetry/Meetings/2017/10/11

Minutes for UCL Proton Calorimetry Meeting, 11th October 2017 (D17, Physics & Astronomy, UCL)

Present

Simon Jolly, Ruben Saakyan, Anastasia Basharina-Freshville, Jordan Silverman, Matthieu Hentz, Dan Walker

ABF:

• Included aluminium to calorimeter simulation.
• Results not significantly different.

MH:

• Running Clatterbridge simulations with collimator in nozzle:
  • Initial simulations used collimator with "exact fit" but particles still transmit around collimator.
  • Adding lip to collimator stops "halo".
  • Increasing collimator diameter shows increase in tail on low energy side of peak.
  • Added cap to collimator: produces very odd energy distribution with second peak at 30MeV.
• Will modify geometry to reduce effect of peak.

JS:

• Running tutorials in Autodesk Inventor.
• Investigating CAD import for Geant4.

DW:

• C++ ROOT macro for reading in Lecroy binary data tentatively working.
• Will start plotting waveforms in ROOT and calculating ADC spectra.
