Apparatus for use in a directional-neutron detector, directional-neutron detectors and methods of use thereof

A directional-neutron detector comprising:

• an opaque housing;
• a structure having a plurality of parallel active channels separated by inactive regions, the plurality of active channels being filled with scintillating material, the scintillating material configured to emit light in response to neutron scattering;
• at least one light collection device coupled to the structure and in optical communication with the structure, a collection face of the at least one light collection device being disposed perpendicular to an axial direction of the plurality of parallel active channels, the at least one light collection device configured to convert the emitted light from the scintillating material into a signal, the light collection device and the structure being contained in the opaque housing;
• and
• a processor coupled to the light collection device and a power supply, the processor configured to process the signal to determine whether the signal resulted from emitted light in response to neutron scattering, and issue a notification based on the determination.
