Abstract
Neutron detector and method utilizing carbon infiltrated boron nitride in its hexagonal form. When exposed to thermal neutrons, this material has been found to scintillate or emit more photons of light per thermal neutron than materials heretofore employed as neutron detectors. The emission of light is further enhanced by enriching the boron nitride in Boron-10, and for neutron radiography, a single emulsion film is placed in direct contact with a carbon activated face of the boron nitride.
Claims14
A neutron detector, comprising carbon infiltrated hexagonal boron nitride which emits light when acted upon by neutrons, means holding the boron nitride for exposure to neutrons, and means for detecting light emitted by the carbon infiltrated hexagonal boron nitride.
In a method of detecting neutrons, the steps of exposing carbon infiltrated hexagonal boron nitride to the neutrons, and detecting light emitted by the carbon infiltrated hexagonal boron nitride in response to the neutrons.
A neutron detector, comprising a body of hexagonal boron nitride having a carbon activated face which emits light in response to neutrons acting thereon, and a light sensitive film in proximity to the activated face for exposure to light emitted by the boron nitride.
In a method of detecting thermal neutrons, the steps of:
- providing a body of hexagonal boron nitride with a carbon activated face, placing a light sensitive film in proximity to the carbon activated face, and exposing the boron nitride to thermal neutrons which cause the boron nitride to emit light which is recorded on the film.
