Abstract

The magnetic field at the origin of the electron confinement in a Hall thruster is established by means of an assembly composed of coils or magnets and a circuit that guides the flux. The standard magnetic architecture, however, suffers from a lack of flexibility as its main purpose is to generate a well-defined topology that warrants a high and stable performance level. This contribution reports on a thruster with an unconventional magnetic circuit that allows covering a broad range of magnetic field topologies. Compared with a classical magnetic circuit, the proposed circuit is especially designed to control in an independent manner all the characteristic parameters of a magnetic topology. The new magnetic structure is mounted in a thruster prototype based on the PPS®1350-ML Hall thruster architecture. The prototype is named PPS-Flex. First, the design and construction of this original magnetic assembly are presented together with functioning of the control interface. Second, the flexibility is illustrated through several examples of achievable magnetic field configurations. Third, experimental results obtained during test campaigns of the PPS-Flex thruster fed with xenon as propellant gas are described and discussed.
