Minutes for UCL Proton Calorimetry Meetings, 20th October


Simon Jolly, Saad Shaikh

Saad Shaikh

  • Headless Pi up and running with libFTDI, ROOT and Apache web server.
    • ROOT fitting performance similar to regular Pi.
    • Will investigate improving Pi speed with Simeon/Petr.
  • Discussion with Connor about stack design:
    • Simon has printed first version of new stack design. Will reprint new version with modifications.
    • New design introduces small air gaps between modules, but significantly simplifies modular design requirements.
  • Discussion with Matt about FPGA and electronics:
    • Will go over FPGA design with Matt to debug signals crossing clock domains and suggest other improvements.
    • Smaller FPGA development board suggested: USB104 A7.
      • Has Zmod connector, which is smaller than FMC but still has enough pins. FMC daughter boards will be produced either way.
      • Board footprint is much smaller than Nexys Video and conforms to USB104 standard, so could be stacked with a mini-PC.
      • Also has required USB DPTI protocol.
    • Worthing purchasing NUC PC to evaluate performance. Currently out of stock.
  • UCLH beam test confirmed for Tuesday 2nd Nov.
    • Will do final equipment test on Monday 1st Nov.
