TI - ECR Discharge in a Single Solenoid Magnetic Field as a Source of the Wide-Aperture Dense Plasma Fluxes J2 - Proc. of ECRIS2020, East Lansing, MI, USA, 28-30 September 2020 CY - East Lansing, MI, USA T2 - International Workshop on ECR Ion Sources T3 - 24 LA - english AB - Sources of dense plasma fluxes with wide aperture are extensively used in applied science, i.e. surface treatment, and as a part of neutral beam injectors. ECR discharge in a solenoidal magnetic field (i.e. with no magnetic mirrors for plasma confinement), sustained by a powerful radiation of modern gyrotrons is under consideration at IAP RAS as a possible alternative to widely used vacuum arc, RF and helicon discharges. The use of a high frequency radiation (37.5 GHz) allows to obtain a discharge at lower pressure, sustain almost fully ionized plasma with density more than 10¹³ cm⁻³, whereas the power on the level of several hundreds of kW allows one to create such a plasma in considerably large volume. In the present work fluxes of hydrogen plasma with the equivalent current density of 750 mA/cm² and the total current of 5 A were obtained. A multi-aperture multi-electrode extraction system design capable of forming the non-divergent ion beam was developed with the use of IBSimu code.
