Objective H- sources are currently used in fusion research, in accelerators and plasma technology. The proposed project deals with a new direction of H- source research - the exploration of Cs-H2 low-temperature plasma properties for negative hydrogen ion generation. The following research will be carried out: the investigation of low-voltage caesium-hydrogen discharge as a new source of H- ions; theoretical investigation of the discharge Cs-H2 plasma diagnostics; diagnostics of negative ions by light absorption; optimization of the discharge parameters for maximum H- yield; the improvement of the existing volume plasma H- sources by using a Cs-H2 plasma in crossed electric and magnetic field volume source and in a tandem volume source. The H- diagnostics by means of the photodetachment technique in Cs-H2 plasma will be developed. The determination of the H- concentration dependence on Cs and H2 mass flows, magnetic field, discharge voltage, emitter temperature and material will be made. The scaling law for the size of the Cs-H2 volume source will be investigated. The role of volume and surface phenomena in the process of H- generation will be analyzed from the information obtained.
