Proton Calorimetry/Meetings/2018/01/17

Minutes for UCL Proton Calorimetry Meeting, 17th January 2018 (D17, Physics & Astronomy, UCL)

Present

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

DW:

• Integration of Leroy binary signals were giving negative results:
  • Probably a result of including rising edge of pulse when calculating baseline.
  • By cutting off the second half of pre-trigger pulse, only 1 pulse giving negative integral.
  • SJ suggests looking at smallest pulses to make sure integration is valid; also check negative result.
  • ABF suggests comparing integration windows of 150 ns and lower to Caen ADC data: currently using window over whole pulse.
• To Do:
  • Fix negative pulse.
  • Adjust timing window to replicate Caen spectrum.
  • Meeting on Monday with Tony Price.

JS:

• Reading (and reading (and reading)) Geant4 manuals, MSci report from MH and PBTWiki pages on Clatterbridge simulations.
• To Do:
  • Will set up meeting with MH to check progress on Clatterbridge simulations.
  • Copy over simulations to user directory to play around with simulations.

ABF:

• Will get JS and DW to check thickness of scintillator sheets.
• Looking
