Minutes for UCL Proton Calorimetry Meetings, 27th January


Simon Jolly, Raffaella Radogna, Saad Shaikh, Fern Pannell

Raffaella Radogna

Saad Shaikh

  • Conducted tests at UCL with Simon to diagnose daisy-chain problem with oscilloscope.
    • Found that DCLK and DVALID have only 2-3ns delay across boards, nothing significant.
    • Managed two fry two boards during experiment, they still work on their own and in daisy-chain, but are quite noisy.
    • Tried delaying DCLK after DVALID is received by 1, 2, 5 and 10us, to no avail.
    • Collected remaining 34 S12915-16R photodiodes at UCL.
  • Contacted Electrical Engineering and Texas Instruments about daisy-chain problems, sent them this presentation.
  • Continued work on USB interface. Fixed a few bugs and all is stable but need to improve handling of data sent from PC to FPGA.
  • Will add features to DAQ framework:
    • Setting number of DDC232 boards remotely.
    • DAQ to start a new file after every 100 measurements.
    • CSV generation to average each file and write averaged, single-line decimals to file.
