The PRIDE project (Proton Range and Imaging Device) aims to integrate a proton computed tomography (pCT) scanner and a proton range verification (pRV) detector into a single device for proton therapy. Our collaboration has carried out extensive work on pCT with experiments taking place in June and December 2022 at the Krakow CCB facility.
Proton range verification (pRV) consists of determining the proton range in a patient during treatment by inferring the Bragg peak position from the detection of scattered secondary radiation. In February 2025, we performed measurements at the Krakow CCB facility to evaluate the components of our setup, using water and PMMA phantoms, and varying the beam energies between 70 and 160 MeV. Two independent measurements were carried out: one with a non-commercial, pure LaCl3 crystal providing excellent neutron-gamma discrimination in a coaxial configuration for independent detection of forward-emitted gamma rays and neutrons, and another with a position-sensitive plastic scintillator combined with two double-sided silicon strip detectors for the detection of laterally scattered neutrons and protons.
In this work, we present a preliminary analysis of the experimental results and discuss their relevance for the development of the integrated PRIDE device, and compare them with Monte Carlo simulations for validation.
