Minutes for UCL Proton Calorimetry Meetings, 4th November

Simon Jolly, Raffaella Radogna, Saad Shaikh, Fern Pannell

Presented quickly preliminary results about PD output slides showing results (updated version)

Managed to run Nexys Video USB tutorial at around 50 Mb/s.
- Will start working on implementing USB interface in DDC232 FPGA design.
Added functionality to send ASCII commands to set FSR remotely.
- Will investigate adding some functionality to set different integration times without reconfiguring FPGA.
Results from LED tests at UCL show increasing fluctuation/noise with longer integration times and smaller FSR - unsure why this is the case. Also observe 0 values in channels, which should not be possible.
- Tested integration time of 2000us with 350pC FSR using ILA: confirmed that CONV remains in sync with CLK and could see many 0s being sent on DOUT under low light levels.
- Could be low light levels with LED.
- Will continue to test setup at UCL with Raffy.
