| Zusammenfassung | Proton therapy (PT) provides dose delivery with high spatial precision, allowing more conformal treatments and the minimization of adverse exposure to adjacent healthy tissues. However, PT is susceptible to uncertainties in the proton range which currently reduces treatment efficacy. To mitigate this, the NOVO collaboration is developing a real-time, multi-particle imaging system capable of simultaneous imaging of prompt gamma rays (PGs) and fast neutrons (FNs) emitted during treatment. This study presents the commissioning experiment of a prototype NOVO detector aimed at imaging a point-like source of accelerator-based neutrons. The array is composed of 14 interwoven organic scintillator bars using two novel scintillator materials - OGS and M600. Experiments were conducted at the Physikalisch-Technische Bundesanstalt in Braunschweig, Germany, where monoenergetic neutron fields from 1.2 MeV to 19 MeV were generated via accelerator-driven reactions. Images of the neutron source were reconstructed through the simple back-projection of double-scattered events, with the detector array position iterated using a two-axis motor table. The source position could be determined with a resolution of less than 5 mm for neutron fields above 14.8 MeV with 10,000 detected events. Further improvements to the array geometry and implementation of advanced reconstruction algorithms suggest detection of range shifts down to 1 mm is possible. |
