Proton Calorimetry/Meetings/2021/09/29

Minutes for UCL Proton Calorimetry Meetings, 15th September

Simon Jolly, Saad Shaikh, Jeremy Ocampo

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)
- Box field treatment plan
- Steer beam towards photodiodes(?)
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.
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.
