Proton Calorimetry/Meetings/2020/06/03

Minutes for UCL Proton Calorimetry Meetings, 3rd June (Everyone is working from home)

Simon Jolly,Laurent Kelleter, Saad Shaikh, Raffaella radogna

Analysed C Nov18 and He and C Apr19 data comparing the reconstructed Bragg curve with GSI DDDs plots
- Not possible to evaluate the goodness of the range reconstruction: GSI DDD energy steps are different from HIT, beam settings are also not clear (we don't know if a ripple filtre was used and the beam offset.)
- We will need HIT DDDs for proper comparison
Will read ch9 and ch2 of Laurent;s thesis
Will make a windows partition for FPGA programming
- will investigate with Tony ans Simon the available Win OS license
First two prototypes of the customised front-end board arrived at CosyLab
- Marko tested the power supply and reference voltage
- one board will be shipped to Saad and the other to Raffy
- Marko will prepare cable for connecting board to power supply and to the FPGA board PMOD.
- Marko will also configure resistors for stand-alone operation.

Finished reading and giving feedback on Laurent's thesis.
Tested He and C fitting using GSI DDDs as reference.
- Can't say much about quality of fitting and Bragg curve reconstruction as GSI data uses a ripple filter and has different energy steps to HIT. Need to compare with actual HIT FLUKA simulation.
Finished Udemy online course on FPGA programming.
- Some useful introductory exercises using basic I/O on Zybo board beyond "Hello World" Blinky exercise.
- Will move onto Xilinx University Programme material to continue training.
Front-end boards have been made by CosyLab!
- Will analyse datasheet for TI DDC232 to understand I/O signals and present report on timeline for operation.
Need to get serial interface working to send commands from computer to FPGA.
- Have downloaded Tera Term terminal emulator, will find example code to get it working.
- Need to buy USB-UART converter expansion module for Zybo Z7 to communicate with FPGA without having to go through on-board processor.
Will start going through example Verilog code for DDC264EVM FPGA serial interface.
