説明

In order to apply a sheet plasma type of volume produced H^-, D^- ion source to injection of proton accelerators and neutral beam injection of thermo-nuclear fusion researches, a large sheet plasma of width 20∿25cm and length 30cm is produced under a discharge current of 175A, a H_2 or D_2 gas pressure of about 2.5×10^<-3> Torr and gas flow of (2.0∿2.5) Torr l/sec in a magnetic field of (60∿110) gauss. Thus, H^- or D^- ion current is extracted in a current density up to 19mA/cm^2 or 16mA/cm^2 which is uniform within 10% over a large area (above 250cm^2) of the sheet plasma surface, and in an acceleration voltage up to 4.5kV. Then, an electron current accelerated with H^- or D^- ions is reduced neglisibly beyond a distance of 2cm from final acceleration electrode.
