The discharge characteristics of a prototype ion source for the Korea Superconducting Tokamak Advanced Research neutral beam system, which has been developed to meet the specification of 120 keV and 65 A beam during 300 s, were investigated. The relationships between the operation conditions, such as the filament current, the arc current (up to 1200 A), the pressure of the ion source, and the measured plasma parameters were studied, and the possibility of steady-state operation was checked. Langmuir probes were used in measuring the plasma parameters and the density distributions. The hydrogen ion density was 2.0×1011 cm−3, the electron temperature was lower than 5 eV, and the plasma uniformity around the bucket was within 30% in the optimum operation conditions. © 2000 American Institute of Physics.
