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.

JS:

• Working on different visualisers for tutorials.
• Tried using Google visualisation package (the name of which escapes us...).
• Waiting on information from Tony Price on Geant4 visualisation: SJ will chase up...

MH

• Running Clatterbridge simulations that Anastasia has been demanding!
• Working on splitting many particle simulation to increase proton numbers at nozzle.
  • Having trouble killing particles...
  • Will split simulation into 4 steps.
• Wiki needs updating.

LK:

• Been learning Java for PHAS3459.
• Will add in latest results to Build-Up publication, but also need to speak to Adam.
• Will email Michela Esposito and Tony Price regarding MAPS readout.
• SJ will contact Claus-Stefan Schmitzer regarding OMA placements.

DW:

• Shelved Java and Python versions of Lecroy binary file readout: all now in C++.
• Next step is to read data into ROOT.
