Minutes for UCL Proton Calorimetry Meetings, 15th September

Present

Simon Jolly, Saad Shaikh, Jeremy Ocampo

Saad Shaikh

• Met with Raffy to discuss poster for IEEE NSS MIC
  • Raffy to draft landscape version of poster and slides for video presentation.
  • Will meet again to discuss recording of video.
• Raffy mentioned that we have a UV LED already, will look for it.
  • Will take care not to dismantle detector after next UCLH beam in order to take calibration measurements with UV LED.
• Simon has heard back from Andy: UCLH beam test possible within next 1-2 months. Exact date TBC. Measurements to be made:
  • Background & calibration
  • Pencil beams, 70-110 MeV, 3 currents (high, low, very low)
  • ±5mm in x-y plane for given z
  • Range steps, no x-y scanning (demo live fit)
    • Will investigate behaviour of live fit when detector is seeing darkness. May require some gating feature.
  • Box field treatment plan
  • Steer beam towards photodiodes(?)
• Will test experimental setup next week. CMOS sensor to not be used.
• Beam test at Clatterbridge likely to not happen until new year.
• Fern has provided headless Pi, will take home to test.
  • Need to set-up static IP address in order to use WiFi.
  • Probably easiest to SSH from Mac when using it.
• Looking into multi-threading for live fitting.
• Brief investigation into executing bash commands from webpage, this forum post may be useful.
• Discussed first version of Connor's stack design:
  • Main issue is providing enough support for sheets of different sizes.
  • Current method would require entire detector recalibration if a module is removed.
  • Is there a way of securing 32 sheets in a gapless holder?
  • Will reconvene with Connor to discuss feedback.
