Minutes for UCL Proton Calorimetry Meetings, 2nd December

Present

Simon Jolly, Raffaella Radogna, Saad Shaikh, Fern Pannell

Saad Shaikh

• Took further measurements at UCL with Raffy using DDC232 board. Office measurements still noisy, so need to figure out how to shield electronics.
  • Will take light measurements at home using UV torch.
• Created live version of Laurent's ROOT quenched Bragg fit – tested with data from HIT April 2019 converted into hexadecimal format to simulate photodiode data.
  • Can achieve roughly 3.5 FPS if binned fit is not chosen.
  • Will see if macro can be optimised further.
• USB interface will require using libftdi on Windows, in order to use ILA for debugging while capturing data. Currently unsure if this is possible.
• Will compare readout speeds of DDC232, DDC316 and DDC118 for full size detector, assuming 1:1 photodiode to input mapping.
• Laptop has been purchased using Raffy's hardware grant. Simon still happy for me to keep it. :)
  • Remaining £1k from HEP could be put towards a laptop later down the line.

Fern Pannell

• Need to get Java file outputting dummy data straight into a directory on the HEP server
  • Should make debugging the GUI code easier; behaves differently with local data
