New large scale accelerator facility called RAON is under design in Institute for Basic Science (IBS, Daejeon, Korea). Both technics of rare isotope production Isotope Separation On-Line (ISOL) and In-Flight Fragmentation (IF) will be combined within one facility for the first time to provide wide variety of rare isotope ion beams for nuclear physics experiments and applied research. Electron Beam Ion Source (EBIS) charge breeder will be used to prepare rare isotope ion beams produced by ISOL method for efficient acceleration. Beams of different rare isotopes will be charge-bred by an EBIS charge breeder to a charge-to-mass ratio (q/A) ≥ 1/4 and accelerated by linac post-accelerator to energies of 18.5 MeV/u. RAON EBIS charge breeder will provide the next step in the development of breeder technology by implementation of electron beam with current up to 3 A and utilization of wide (8') warm bore of 6 T superconducting solenoid. The design of RAON EBIS charge breeder and results of dumping of high power DC and pulsed electron beam into collector will be presented and discussed.
