To apply a SHEs ion-beam to physical and chemical investigations, we have been developing ion sources that apply to a short-lived single atom. We employed the Electron Beam Generated Plasma (EBGP) method to ionize an element with high ionization energy. The EBGP ion source can ionize an element or a molecule of nuclear reaction products by bombarding an electron beam that accelerated between the cathode and the anode electrode. In this work, we built the EBGP ion source and searched for an optimum condition ionization of a single atom.
