Proton Calorimetry/Meetings/2021/01/20

Minutes for UCL Proton Calorimetry Meetings, 20th January

Simon Jolly, Raffaella Radogna, Saad Shaikh, Fern Pannell

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 one, 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.
