Design of insulation support system of 120 keV positive ion source accelerator
Abstract In order to support the physical research on the EAST tokamak, a new positive ion source with designed beam energy of 120 keV was proposed to be developed. Accelerator structure is one of the key components of the ion source. Through the finite element analysis method, the electrostatic analyses of insulators and grid plates were carried out, the material and structure parameters of insulators were determined. The maximum electric field around each insulator is about 4 kV/mm, and the maximum electric field between grids is about 14 kV/mm, which can meet the 120 keV withstand voltage holding. The insulation system for the positive ion source accelerator with 120 keV is designed, and the connection and basic parameters of insulators and support flanges are analyzed and determined.
