3He beam development of 18 GHz SCECR-IS for proton generator at RCNP

Proton generator of several MeV for easy use like calibration of charged particle detector is needed instead of cyclotrons or electrostatic accelerators like Van de Graaff. So a proton generating system which consists of 18 GHz superconducting (SC)-ECR ion source and deuterated polyethylene target has been developed at the Research Center for Nuclear Physics (RCNP), Osaka University. The 3He2+ beam of 200eμA has been provided by SC-ECR ion source with 20 keV acceleration voltage and as a result of feasibility test of 3He+deuteron (D)→proton(P)+4He fusion reaction, the protons of 14.67 MeV have been obtained in 0.5Hz successfully.
