Large-diameter ion-optical systems are widely used in gridded ion thrusters for missions near-earth space and deep-space research. Ion sputtering of the accelerator grid is main factor that limits thruster’s life. The use carbon-based materials with a lower rate compared to metal grids allows thruster increase its life more than four times. most resistant mechanical loads made carbon-carbon composite materials. Traditionally, optics circular-shaped apertures centers located nodes hexagonal...
The results of plasma simulations in a discharge chamber Direct Current gridded ion thruster are dependent on the choice anomalous electron conductivity model. Usually, additional diffusion is used to reproduce experimental level. Up-to-date, existing numerical models use different values coefficient, and this often nonrigorous or insufficiently justified. In research, influence coefficient an axisymmetrical Full-Particle Cell simulation was investigated. modeled had rated power 3 kW, thrust...
