Proton Calorimetry/Meetings/2018/11/07

Minutes for UCL Proton Calorimetry Meeting, 7th November 2018 (D17, Physics & Astronomy, UCL)

Present

Simon Jolly, Matthieu Hentz, Laurent Kelleter, Jeremy Ocampo, Saad Shaikh, Fernando Franco Felix, Ohie Mayenin

JO:

• Attending HEP lectures: HEP Monday and Tuesday, CDT Thursday.
• Going through Geant4 simulations: cannot view graphics on Windows laptop...
• Laptop has been ordered by SJ and Tony Hoare.
• Met with Jamie McClelland and Adam Gibson on 18th October: have been provided with reading list.
• Will take Medical Physics/CDT courses next term: Numerical Optimisation and Inverse Problems.
• To Do:
  • Try analysing Geant4 simulation results in Python.
  • Background reading!

MH:

• Pure Geant4 pCT simulation matches results from GATE.

Multithreaded simulations result in multiple data files:

• • Geant4 cannot merge them itself.
  • Possible to merge manually.
  • RR suggests that merging should work automatically: will investigate.
• To Do:
  • Build application for Legion cluster: need to speak to Research Computing.
  • Test application on HEP and Legion clusters.

SS:

• Looking through data from Birmingham experimental runs.
• Results generally look good:
  • Clear double peak for eyepatch data.
  • Some spectra show unexpected double peaks: SJ suggests PMT rate effects.
• To Do:
  • Analyse scope data by Christmas.
  • Take data for LeCroy scope trigger rate test.

FFF:

• Background reading on proton therapy: LK recommended Paganetti: Proton Therapy Physics.
• Met with LK to discuss detector development.
• Two potential ideas for Masters project:
  • Complete range calorimeter simulations.
  • Front end electronics design and readout.
• Will contact Ruben Saakyan to discuss options and find out more about light detection options.

LK:

• Working on build-up simulation paper: need to check LET definition.
• Debugging Geant4 simulations with CentOS 7 environment.
• Organisation of HIT trip.
