Summary:Description of a negative-ion surface plasma source being built in Novosibirsk as a basis for the production of high energy neutrals. The source is a pulsed system consisting of a gas discharge chamber of planotron geometry producing a gas discharge across a magnetic field in a ring gap between a spool-shaped cathode and a ring anode encasing the cathode. The high-current discharge has a current density of up to 100 A/sq cm at the cathode and a transverse voltage drop of 100 to 150 V. The yield and composition of the negative ions produced are dependent on the cathode materials, of which molybdenum showed the best performance.
