This article presents a model setup of neutron sensors consisting of a Li-glass scintillator coupled with a silicon photomultiplier (SiPM) array. The newest developments based on SiPMs array enable high-gain and the low-light detection capabilities of the traditional photomultiplier tube (PMT) while offering the benefits of a solid-state sensor: low-voltage operation, insensitivity to magnetic fields, reduced dimensions, and mechanical robustness. Measurements conducted with the presented setup were complemented with the Monte Carlo N-Particle Transport Code (MCNP) numerical simulations for larger systems. The results indicate the feasibility of utilizing the presented technology for highly sensitive handheld neutron radiation detectors in compliance with the requirements of IEC 62534 standards.
