Abstract

See full text

A magnetic circuit for creating a magnetic field in a main annular ionization and acceleration channel of a Hall-effect plasma thruster, having an open top end for emitting ions and a closed bottom end, includes outer magnets comprising a bottom annular outer magnet, and a top annular outer magnet disposed above the bottom outer magnet; inner magnets comprising a bottom inner magnet, of cylindrical form having a bottom part of a diameter less than the diameter of a top part, disposed below the top outer magnet, and a top annular inner magnet disposed above the bottom inner magnet; the outer magnets having a same pole (N, S) on their respective top face and an opposite same pole (S, N) on their bottom face; the inner magnets having an orientation of their poles that is the reverse of that of the outer magnets; and the outer magnets and the inner magnets being disposed above the closed bottom end of the annular channel.
