We describe models for the long-pulsed surface-plasma multiaperture quasi steady-state with a hydrogen negative ion output of up to 1 A, with an emission current density of 2 A/cm{sup 2}, and with an average current density in a beam of 60 mA/cm{sup 2}. The gas efficiency for the production of H{sup {minus}} beams was 12--17%. The experimental and the simulated efficiencies of the negative ion production of pure hydrogen and cesiated surface-plasma sources with geometrical focusing are compared.
