Minutes for UCL Proton Calorimetry Meetings, 20th October

Present

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.
