Proton Calorimetry/Meetings/2019/02/27

Minutes for UCL Proton Calorimetry Meetings, 29th/30th January 2019 (D12, Physics & Astronomy, UCL)

MSci Meeting, 26th February (D12, Physics & Astronomy, UCL)

Present

Simon Jolly, Ohie Mayenin, Saad Shaikh, Raffaella Radogna, Jeremy Ocampo

Jeremy Ocampo

• Looking into optical light production from Cherenkov and scintillation in Geant4.
• Struggling to implement realistic photon production with phase space file: SJ suggests contacting Ben Morgan <ben.morgan@warwick.ac.uk at Warwick.
• Will start looking into spatial distribution of light production and photon counting: also conversion between light production and dose.
• Not attending courses: easier doing coursework remotely.

Saad Shaikh

• Checking scale factors for comparing Caen and LeCroy spectra.
• Looking into peak signal size to compare different PMMA thicknesses.
• Writing first draft of final report: should send to SJ in a week.

Ohie Mayenin

• Issues with Clatterbridge BDSIM simulation: odd results from some runs but not others:
  • Magnet field strengths arbitrarily changed.
  • Beam loss at some quadrupoles.
  • Jacinta is investigating.
• Preparing for Clatterbridge trip on 28th Feb.

MSc Meeting, 13th February (D12, Physics & Astronomy, UCL)

Present

Simon Jolly, Fernando Franco Felix, James Golbourn, Raffaella Radogna

James Golbourn

• Researching uses of IBA Lynx and Sphinx:
  • Sphinx coupled to Lynx used for daily QA.
  • Lynx is scintillator screen; Sphinx is series of RW3 absorbers used for range checks.
• Looking into different uses of scintillators and scintillating fibres.
• Investigating radio chromic films.
• Will contact Alison Warry with questions arising from previous talk.

Fernando Franco Felix

• Handbook on photodiodes provided by Hamamatsu: using it for minimum and maximum power calculations.
• Will contact Hamamatsu to confirm calculations.
