In order to apply the ion beams of superheavy elements with atomic number over 100 to physics and chemistry research, we constructed an EBGP (Electron Beam Generated Plasma) ion source as an ion source applicable to short-lived single atoms. The EBGP ion source was installed in the JAEA-ISOL (Isotope Separator On-Line), and ion beam generation in various ionization conditions has been conducted with several noble gases. As a result, we confirmed the ion source worked in a stable condition, and an ion beam was successfully generated.
