Parametric Optimization of a Hall Effect Thruster Magnetic Circuit

Abstract

A Hall effect thruster (HET) incorporates a magnetic circuit that must generate a specific flux density spatial distribution inside and near the outlets of the plasma channel. The first objective of the design process of this type of structure is to obtain a specific magnetic filed topology in the thruster channel by fixing radial and axial components of the magnetic field and a certain inclination of magnetic flux lines. The aim of this work is to develop a tool for solving this inverse magneto static problem, which is applied to the SNECMA PPS1350 ^® HET magnetic circuit in order to obtain a new “Low-Erosion” magnetic configuration.
