title: Emission characteristics of H- ion source with inverse gas magnetron geometry.
abstract: 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/cm(2).
