We have been developing an EBGP (Electron Beam Generated Plasma) ion source1 coupled to the gas-jet transport system to produce SHE ion beams for rapid chemical experiments. The EBGP ion source ionizes atoms and molecules by electron impact and is expected to produce ion beams of various elements. We have succeeded to produce ion-beams of several noble gases using the present ion source, and it has been found that the beam intensities increase with increasing atomic number. We report on the ionization of various short-lived nuclides produced in spontaneous fission of Cf.
