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.

Raffaella Radogna

  • Almost finished consolidating PBT setup scripts for CEntOS 7.
  • Will discuss with James Chappell about integrating BDSIM setup.

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.
