概要	A steady-state electron cyclotron resonance ion source with large spherical electrodes has been developed to study the plasma wall interaction, erosion mechanism, and hydrogen retention of first wall materials in a nuclear fusion reactor. Discharge characteristics of the ion source were studied in terms of microwave power, magnetic field configuration, and gas (H-2) pressure. Ion saturation current density J(is) of about 21 mA/cm(2) near the electrodes (target value is 20 mA/cm(2)) was achieved with microwave power of 3.0 kW and magnetic field of 2.3 kG at an optimal gas pressure.
