Minutes for UCL Proton Calorimetry Meetings, 20th January

Present

Simon Jolly, Raffaella Radogna, Saad Shaikh, Fern Pannell

Saad Shaikh

• Met with Marko to discuss bugs in daisy-chaining – he suggested to test signals with oscilloscope.
  • Slowing down DCLK to 5MHz and shuffling board order had no effect.
  • Will meet Simon at UCL on 21st to debug daisy-chain with oscilloscope.
• Continued work on USB interface:
  • Reset, Pause and Full-Scale Range commands can be sent from C++ macro.
  • Bash script can run DAQ and processing scripts simultaneously.
  • If file data is stored in is only opened/closed once, DAQ keeps up with integration rate. Otherwise measurements are missed.
  • Still need to iron out a few bugs...
• DAQ framework:
  • FTDI.cpp should write to a new file every 100 measurements, opening and closing each file just once to optimise speed.
  • WriteCSV.cpp should read each file, convert and average measurements, and overwrite a single-line CSV file.
  • Can then think about incorporating a fit and writing the fit results to file as well.

Fern Pannell

• MSci Progress Report submitted to Simon
• C++ compiles on Raspberry Pi terminal:
  • Navigate to file location
  • $ g++ filename.cpp
  • $ ./a.out
• Installed libFTDI on the Raspberry Pi
  • Problems getting the FTDI C++ code to run successfully, most likely not pointing the code to the correct path for libFTDI1 installation
  • Will meet with Saad to get this up and running for next week
• Submitting all HEP PhD applications this week
