ECR Light Ion Source
摘要
Abstract
This article describes the development and adjustment of two designs of ion sources generating plasma at a frequency of 2.45 GHz. These ion sources operate in the modes with ECR discharge and RF-discharge. The working gas of the sources is helium or hydrogen. The extraction and beam formation system currently represents two-electrode optics. The diameter of the emission hole is 4 mm. At an accelerating voltage of 25 kV in the pulsed mode. The ion beam current was 7 mA (He+) with a helium ion fraction of up to 70% and 14 mA (H+) with a proton ion fraction of up to 90%.
