ECR Discharge Sustained by Millimeter Waves as a Source of Dense Plasma Flux

The results of the investigation of the dense ECR discharge hydrogen plasma flux formation in the magnetic field of a single solenoid are presented in this work. The transversal flux profile obtained at the optimal system parameters is shown. The possibility of the formation of homogeneous plasma fluxes with density of 750 mA/cm 2 and total current of 5 A is demonstrated. The results of the first experiments of the hydrogen ion beam extraction from the ECR discharge plasma in the single magnetic coil are presented. The record values of the ion current density higher than 1.5 A/cm 2 were obtained. The results of the research presented in this paper show the prospects of the proposed system for applications such as the neutral beam injector development for the plasma heating in the controlled fusion facilities.
