  • High current proton beam target
    Patent number: 6215851
    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 13C 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 13C gamma reaction layer for chemically bonding therewith.
