Proton Calorimetry/Meetings/2017/10/04

Minutes for UCL Proton Calorimetry Meeting, 20th September 2017 (D17, Physics & Astronomy, UCL)

Present

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

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...

ABF:

• Detector simulations now include hexagonal module and Clatterbridge nozzle collimator.
• Trying to pin down origin of non-Gaussian shape of ADC peak from Clatterbridge data:
  • Background measurements do show low energy peak but nothing at high energies.
  • Low energy peak slightly reduced due to absorption in 4cm PMMA.
  • Using Matthieu's latest simulations with 2mm collimator does show a non-Gaussian shape on main peak but not large enough.
• RS suggests putting an angle on the collimator in MH's simulations to check the effect.
• Also modifying mylar thickness to check effects.
• Have all parts for boosted PMT: should be ready to test.

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.
