Saad Shaikh

  • Tested DDC232 daisy-chain with resistors, experimental runs listed here.
    • Will send another email to Clive and Izzat to ask for help.
    • Raffy to get in touch with Marko to get a quote on new DDC232 boards made.
  • Added new details to the DDC232 page, with latest version of FTDI code.
  • FTDI code works on Raspberry Pi, with only a few changes to compile command.
    • ftdi_tcioflush function not found, but older deprecated version can be used instead.
    • Pi is slow, with average time between measurements at about 650us instead of 180us.
    • Will benchmark performance of "minimal" version of FTDI code, where data is collected but not processed.
    • Will also benchmark performance of "full" and "minimal" versions of FTDI code on Windows.
  • Will compare channel noise of single DDC232 board with alternate photodiodes replaced with resistors.
  • Will start investigating non-ROOT-based fit.
    • Raffy has suggested to use GNU scientific library.

Fern Pannell

  • Curve with >>16 points can now be displayed over the 16 photodiode bars.
    • New Java dummy data generating file has been written to create curve data.
    • Line one contains 16 values (photodiode bars)
    • Line two contain 16n values (y values of curve points)
    • JavaScript then attaches an x-coordinate to each y value when parsed
    • Utilising a second (hidden) x-axis on the chart for the curve, the line is shown over the bars.
  • Will need to start considering deploying a localhost to run this process locally - move away from SSH to the HEP server.
    • I have experience with the node.js http-server so will test initially with this. The Apache web server will likely be the lasting choice to host the display, which can be investigated after the http-server tests are successful.

PhD Update:

  • Accepted PhD position at UCL.
  • Proton-driven Plasma Wakefield Acceleration (AWAKE), with Matthew Wing.
