Emission characteristics of H- ion source with inverse gas magnetron geometry

The work is dedicated to the experimental investigation of the intense volume-plasma H- ion source. Preliminary experimental researches of two parameters of the upgraded source - emission density of H- ions and gas flow - are represented below. In plasma volume of noncesium H- ion source, the conditions for obtaining of increased density of H- ions in the field of adjoining to the emission aperture were realized. The advancing of electrode system of the emission chamber of a source has allowed receiving the value of an emission density of H- ions equal to 600 mA/cm2.
