Minutes for UCL Proton Calorimetry Meeting, 28th February 2018 (D17, Physics & Astronomy, UCL)

Present

Simon Jolly, Anastasia Basharina-Freshville, Matthieu Hentz, Jordan Silverman, Dan Walker, Laurent Kelleter

DW:

• Took data with fast treatment plan verification prototype on 21st February.
• Data received from Tony Price:
  • Spectra look messy with significant energy spread.
  • Can see difference between with and without polyethylene sheet.
• Everything written up on Wiki: just need to add photos.
• To Do:
  • Extract PRaVDA tracking data.
  • Email Tony Price and check exact energy and find out whether they have any energy spread data.
  • Correlate with scintillator pulses.
  • Create 3D dose distribution.

JS:

• Working on building CAD models of Clatterbridge beamline.
• Certain components are not specified correctly or overlap: SJ has provided most up-to-date drawings he has; MH will do the same.
• To import models into Geant4:
  • Break each model down into constituent parts.
  • Create assembly of all components made of the same material.
  • Export this model as an STL-File (meshed CAD model).
  • Convert each material STL-File into GDML.
  • Import this meshed GDML file into Geant4 as given material.
• To Do:
  • Finish CAD model for MH's simulation.
  • Define vacuum for initial vacuum tube.
  • Rerun simulations to check differences in simulations with CAD components.

LK:

• Finished 3D printed cover for bridge over ISDI sensor bond wires.
• To Do:
  • Install software on DAQ PC: DSLR software, EPIX card drivers and software, LabView, Aspect software (once we have it).
  • Test sensor.

ABF:

• Scintillator sheets now polished: most of the scratches now removed.
• To Do:
  • Install software on DAQ PC: Caen digitiser and HV.
  • Packing inventory.

MH:

• Course deadlines are a week earlier than anticipated...
• Geant4 Clatterbridge simulations finished.
• To Do:
  • Update Wiki.
  • Submit coursework.
