SOURCE OF ION BEAM BASED ON ELECTRON-CYCLOTRON RESONANT DISCHARGE PLASMA, HELD IN OPEN MAGNETIC TRAP

摘要

FIELD: physics.;SUBSTANCE: invention relates to forming a high-current ion beam by its extraction from a dense ECR discharge plasma created in an open magnetic trap by powerful radiation of a millimeter wavelength range. Developed device can provide efficient extraction of ions from a dense ECR discharge plasma and formation of high-current ion beams with low emittance and at the same time it can provide a transition to a regime of improved confinement of plasma in a trap with suppression of transverse transfer of plasma caused by flute instability. Developed ion source allows to form ion beams from a dense plasma with a current to an ampere ratio and an emittance value up to 0.01 π mm⋅mrad in normalized units.;EFFECT: formation of ion beams from a dense plasma.;4 cl, 2 dwg
