Minutes for UCL Proton Calorimetry Meetings, 6th October


Simon Jolly, Saad Shaikh

Saad Shaikh

  • Registered for IEEE NIS MCC 2021.
    • Recorded video presentation and edited poster/slides. Will edit video once Raffy films.
  • Implemented simple live fit gate:
    • Using ratio between average photodiode value and peak value. With noisy data between 70-110 MeV, 1.8 seems to be a good cut.
  • Spoke with Lorzeno Moneta about multi-threading, does not seem that ROOT-based multi-threading improves speed.
  • Spoke with Ruben and Anastasia about optical gel: standard "550" should work.
    • Applied expired gel to a photodiode as a test. Simon to order more.
  • Spoke with Connor about stack design:
    • Simon proposed improvements on current working idea, using large area plates to apply force and shallow front cap with corner edges.
    • Connor to mock-up design and get back in touch.
  • Partially tested experimental setup:
    • FPGA/photodiode cabling done, need to test networking, DAQ laptop and Pi.
    • Tape removed from scintillator sheets, edges require cleaning with isopropyl.
  • Will setup and test headless Pi.
