    摘要: A Hall effect plasma accelerator comprises an annular accelerating channel. A radial magnetic field is applied across the channel between magnetic poles of opposite polarity. Instead of these magnetic poles being linked by magnetic material extending around the closed end of the channel so as to form a single magnet, the invention proposes that the magnetic poles be defined on bodies of material which are magnetically separate. This allows the designer to have greater freedom in selecting the dimensions of the thruster in general and of the magnetic system in particular, thereby giving an opportunity to improve thruster efficiency and to manufacture thrusters having a wide variety of different shapes depending on available space.

    摘要: In a Hall effect thruster, especially for use in manoeuvring satellites, a stream or plume of ions, used to produce the thrust is deflected, by appropriate adjustment of a magnetic field, so as to steer the satellite or other vehicle. The channel (20), along which the ions are accelerated, is preferably flared outwardly at its open end (22A) so as to avoid erosion which would otherwise be caused by the deflection. The adjustment of the magnetic field is preferably achieved by dividing an outer magnetic pole, surrounding the channel, into separate sectors (38A, 38B, 38C, 38D) and winding individual electric coils (18, 18', 19, 19') around the sectors. Control of the current through these individual coils is used to make the appropriate adjustments of magnetic field.
