A proton-recoil track imaging system for fast neutrons: the RIPTIDE detector

Fast neutron detection is often based on the neutron-proton elastic scattering reaction: ionization caused by recoil protons in a hydrogenous material constitutes basic information for design and development of class detectors. Although experimental techniques have continuously improved, proton-recoil track imaging remains still at frontier n-detection systems, due to high photon sensitivity required. Several state-of-the-art approaches tracking using n-p single double - referred as Recoil Proton Track Imaging (RPTI) can be found literature. So far, they showed limits terms efficiency, complexity, cost, implementation. In order address some these deficiencies, we proposed RIPTIDE novel recoil-proton detector which light output produced fast scintillator used perform complete reconstruction space time interaction events. The idea viable thanks dramatic advances low noise counting achieved last decade new scientific CMOS cameras well pixel sensors, like Timepix or MIMOSIS. this contribution, report concept: Geant4 Monte Carlo simulations, collection tests approach image readout, processing analysis.
