Description
RIPTIDE is a novel fast-neutron detector concept designed to determine both the energy and the direction of incident neutrons through indirect detection via neutron-proton elastic scattering. The converter medium consists of a cubic plastic scintillator (BC408, 60 × 60 × 60 mm³), where neutron-proton scattering events can generate recoil protons that produce scintillation light. This light is collected through a lens system and an image intensifier (MCP with a phosphor screen) and subsequently recorded by a fast CMOS camera, yielding a digital image of the event.
We present the first study of an experimental apparatus in which different cubic scintillators (BC408, CsI(Tl), and GAGG) are tested to investigate the possibility of detecting minimum ionizing particles, whose light yield in scintillators is significantly lower compared to protons. To increase the available information, two faces of the scintillator cube can be imaged simultaneously using a mirror. In this first setup, we successfully observe muon scintillation tracks in the CsI(Tl) crystal and obtain the first images showing two projections of a single track.
In parallel, a Monte Carlo simulation is performed, and a comparison between simulated and experimental data is presented. Finally, we report the first preliminary results on the three-dimensional reconstruction of muon tracks inside the scintillator.
