Radiography apparatus using gamma rays emitted by water activated by fusion neutrons

Radiography apparatus includes an arrangement for circulating pure water continuously between a location adjacent a source of energetic neutrons, such as a tritium target irradiated by a deuteron beam, and a remote location where radiographic analysis is conducted. Oxygen in the pure water is activated via the {sup 16}O(n,p) {sup 16}N reaction using 14-MeV neutrons produced at the neutron source via the {sup 3}H(d,n) {sup 4}He reaction. Essentially monoenergetic gamma rays at 6.129 (predominant… more

Radiography studies with gamma rays produced by 14-MeV fusion neutrons

Oxygen contained in pure water has been activated via the {sup 16}O(n, p){sup 16}N reaction using 14-MeV neutrons produced at a neutron generator with the {sup 3}H(d,n){sup 4}He source. Photons of 6.129 and 7.115 MeV, generated by the decay of 7.13-second {sup 16}N, were then used to demonstrate the feasibility of employing highly penetrating, nearly monoenergetic gamma rays for radiography studies of thick, dense objects composed of elements with medium to relatively high atomic numbers.
