FRPT 2023 – Toronto (CA)


Sara Pettinato presented “A NOVEL DIAMOND-BASED DETECTION SYSTEM FOR PULSE-BY-PULSE DIAGNOSTICS OF ELECTRON BEAMS IN FLASH RADIATION THERAPY” work at the international Flash Radiotherapy and Particle Therapy Conference held last December in Toronto, Canada.

A custom-made diamond dosimeter, coupled with a specifically developed gated-integrator, was characterized under High Dose-Per-Pulse electrons generated by an ElectronFlash apparatus at SIT laboratories (Aprilia, Italy). The dosimetric system was characterized with 7 MeV electron pulses of different duration and different pulse repetition frequency.

The experimental results outlined in this study, acquired in the last months of 2023, serve as the launching pad for the Ophelia project. Indeed, they demonstrate the effectiveness of the proposed detection system in real-time monitoring of the dose released by each pulse, even for pulses with amplitudes > 10 mA (i.e., two orders of magnitude higher than what conventional instrumentation used by medical physicists can acquire).
