Laboratory ECR Source of Light Ions with a Resonant Discharge Chamber for Installation on a High-Voltage Platform

Within the framework of the BELA project (Based on ECR ion source Linear Accelerator), designed to solve various problems, an injection complex based on several ion sources is being created. One of the tasks is multibeam irradiation of structural materials of nuclear and thermonuclear power plants to analyze their radiation resistance. Heavy (Fe) and light (H2/He) ion beams will irradiate the target in the same chamber simultaneously. To generate beams of light ions, a compact ion source based on electron cyclotron resonance (ECR source) is being developed. The paper contains description of the studies of the dependences of the operation of an ECR source of light ions with a resonant discharge chamber on the pressure of the working gas, the magnitude and distribution of the magnetic field, as well as the mass-charge spectrum of a helium-ion beam.
