Abstract
Gas-filled neutron detectors, an imaging system and an array of such detectors are provided. Surfaces or surface portions incorporated into the gas-filled neutron detectors are coated with and/or composed of at least partially, neutron reactive material. The surfaces may be flat or curved, fins or plates, foils, thin sheets, porous or filamentary material, or semi-solid material or aerogel. The incorporation of the extended surfaces coated with or composed of neutron reactive material increases the neutron detection efficiency of the gas-filled detectors. The surfaces can be made of conductive, semiconductive, semi-insulating, or insulative materials. The surfaces are arranged such that they do not detrimentally detract from the main function of a gas-filled detector with particular attention to gas-filled proportional detectors. The surfaces may be arranged in the detectors to allow for modular construction. The surfaces are designed and arranged such that more than a single reaction product may escape the surface.
