Proton Calorimetry/Meetings/2017/10/18

Minutes for UCL Proton Calorimetry Meeting, 18th October 2017 (D17, Physics & Astronomy, UCL)

Present

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

LK:

• Just got back from holiday.
• Writing build-up publication.
• Writing poster for Munich school and OMA meeting (5–9 November).
• Needs access to IPS account: SJ to organise.

JS:

• Literature Review deadline: Monday 23rd October.
• Set up Virtual Box on Windows laptop for viewing Tony Price's PRaVDA VM.

DW:

• From now till Monday: Literature Review!
• Working on LeCroy binary data class importing into ROOT:
  • Managed to produce a spectrum!
  • Will put together some slides describing method of spectrum production.

ABF:

• Matthieu's now include more accurate dimensions for cap:
  • Resulting spectrum looks slightly better with increase in low energy side of peak but still not enough...
  • Will take Matthieu's latest particle distributions to check detector response.
• Checked boosted Hamamatsu base with second HV supply:
  • Built HV connector with Derek.
  • Results initially okay, but after half an hour of running something seems to have died...

MH:

• Running Clatterbridge simulations with collimator in nozzle:
  • Improved nozzle cap dimensions so that overlap with nozzle is correct.
  • Odd peak at 30MeV no longer present.
  • Slight broadening in peak but nothing significant.
• Plotting beam intensity profile for Clatterbridge simulations:
  • Large numbers of high energy particles appearing outside the nozzle.
  • Will check origins upstream.
