A radio-frequency-driven hydrogen-ion source of the diagnostic neutral beam has been developed for the Hanbit magnetic mirror device at the Korea Basic Science Institute [S. M. Hwang et al., Trans. Fusion Technol. 35, 99 (1999)]. The three-electrode system with 37 apertures extracts the hydrogen-ion beam with 29.8 keV beam energy and 1.2 A beam current at a 9.6 cm diam. The ion source has the capability of varying the beam pulse width from 10 to 100 ms and also is capable of beam modulation at 50 Hz with a 10 ms flattop pulse width. The beam power and the ratio of the mixed ion species were measured by infrared thermography and Doppler shift spectroscopy, respectively. Most recent experimental results will be presented in this article. © 2002 American Institute of Physics.
