Abstract

Negative hydrogen ions are extracted from a reflex-type sheet plasma. Electron density and temperature profiles are measured with changing the filling gas pressure, and they are optimized to the H^- production at the optimum gas pressure. The optimum gas pressure is 5 mTorr for the discharge current I_d =2 A. As the discharge current I_d increases, H^- current increases linearly corresponding to the density increase in the center region, but saturates above I_d =40 A. The maximum extracted H^- current density of 4 mA/cm² is obtained at I_d=100 A.
