Abstract: Electrical propulsion in space is currently experiencing significant
improvements. Among the electrical space propulsion technologies available,
Hall effect thrusters work on the generation of plasma inside a cylindrical
channel. These thrusters incorporate a magnetic circuit that has to generate
a very specific magnetic mapping inside the plasma channel. There are mainly
two objectives in the design process of this type of structure. The first
objective is to obtain a specific magnetic mapping in the thruster channel
with specific magnetic field radial component values. The second one is to
obtain a specific magnetic field line inclination. Moreover, for spatial
thrusters the minimization of the mass is one of the most important
optimization criterion. The aim of this work is to develop a method for
resolving the inverse magnetostatic problem, which is applied to obtain an
optimized magnetic structure for Hall effect thrusters circuit.
