A large beam facility for the application of high power ion beams has been developed at the Korea Atomic Energy Research Institute (KAERI). The primary usage of this facility is to develop an 8 MW neutral beam heating system for a tokamak, but other applications using a large beam would also be possible in the near future. The facility is composed of a bucket ion source (120 kV, 65 A), related beam line components including a large vacuum chamber (3 m x 4 m x 5 m), power supplies for the ion source, control and DAS (Data Acquisition System), beam diagnostics system, and a water circulation system (2 MW) for cooling of the beam line components. The maximum beam parameters at present are a beam energy of 87 kV and a beam current of 17.5 A with a beam size of 13 x 45 cm2. A maximum pulse length of 10 s could be achieved with a 1 MW beam power. The beam power with a hydrogen ion will be increased up to 7.5 MW during 5 s.
