Description

For simple applications, such as the calibration of a charged particle detector, a multi-MeV proton generator may be preferable to cyclotrons or electrostatic accelerators such as Van de Graaff generator. Thus, a compact proton generating system, consisting of NANOGAN${}^{\mathsf{\text{TM}}}$ and a deuterated polyethylene target, was developed at the Research Center for Nuclear Physics at Osaka University. A 3He2+ beam was generated by the NANOGAN${}^{\mathsf{\text{TM}}}$ with the acceleration voltage of 20~40 kV in an experiment that utilized the fusion reaction 3He + deuteron (D) → proton(P) + 4He. Protons with energies of 14.67 MeV were generated at the atmosphere side of the target in the experimental setup, using a novel target base with a thin nickel foil and Polyimide film window.
