Negative ion surface plasma source development for plasma trap injectors in Novosibirsk
- AN SSSR, Novosibirsk (USSR). Inst. Yadernoj Fiziki
Work on high-current ion sources carried out at the Novosibirsk Institute of Nuclear Physics (INP) is presented. The INP investigations on pure plasma'' planotron and pure surface'' secondary emission systems of H{sup -} generation, which preceded the surface-plasma concept developed in Novosibirsk, are described. The physical basis of the surface-plasma method of negative-ion production is considered. The versions and operating characteristics of different surface-plasma sources including the multi-ampere ({approx gt}10A) source are discussed. Research on efficient large-area ({approximately}10{sup 2} cm{sup 2}) negative ion surface-plasma emitters is described. The INP long-pulse multiaperture surface- plasma generators, with a current of about 1A, are described. 38 refs., 17 figs.
