Abstract

Abstract—Multi-stage depressed collectors used for space applications have several stringent requirements, which mainly include high efficiency and low back-streaming. To accomplish these space requirements, autho rs have proposed a multi-stage depressed collector with hulf-cy lindcr electrodes a nd external ring shaped permanent magnet. The half-cylinder eiectrodes introduce asymmetry in the electric field and the external ring magnet produces radial magnetic field. The cross-field action of the electric and magnetic fields along with the asymmetry introduced, results in zero back-strea ming and very high collector efficiency. After proper optimization of the electrode potentials and magnetic field values, maximum of 95.53% efficiency with zero back-streaming has been achieved, the results of which are presented
