Proton Calorimetry/Meetings/2025/04/01

Minutes for UCL Proton Beam Therapy Group Meetings, 1st April

Joe Bateman, Sonia Escribano, Matt Warren, Harry Barnett, Simon Jolly

String of 8 DDC boards seems to work but only if integration is greater than 600 otherwise overlaps - so need to find ways to make faster

Nuvia invited us out to Prague on w/b 7/4 or 21/4
Spoke to Czech PTC proton physicist about visiting and possible beam time
Fly on Thursday 24/4 - Friday 25/4 at Nuvia, Saturday 26/4 at PTC
- Bring 4 modules with two boards each module but bring whatever we can
Aim for two consecutive evenings in UCLH at some point in May
- Pristine Bragg peaks
- SOBPs
- Moving the QuARC to check effect of measuring beam off axis
Email from Andy Rose at Imperial for advice on integrated FPGA back-end DAQ such as on-chip KRIA (less CPU than pi5 but more FPGA power than USB104)
- Also was able to re-factor Kelleter equation to optimise for computing to be ~700x faster in C++

To-do list prepared for Prague
Fake-generated data to check “live acquisition” calibration and firing
For long runs not possible to kill acquisition from GUI (I.e. stop button stops calibration and fitting) - need to access to ftdi from GUI which is blocked by web servers
On patch panel of Peli case in case pi’s don’t work and need to use DAQ laptop
