Abstract
In accordance with the present invention, there is provided a proton beam target for generating gamma rays which are generated therefrom in response to an impinging proton beam. The proton beam target is provided with a,C gamma reaction layer for generating the gamma rays therefrom. The proton beam target is further provided with a stopping layer for mitigating transmission of the proton beam therethrough. The stopping layer is formed of a refractory metal which is hydrogen soluble for dissolving implanted hydrogen molecules therewithin as a result of the impingement of the proton beam and which is chemically reactive with the,C gamma reaction layer for chemically bonding therewith.
