Abstract
A Hall-effect thruster (10), configured to be arranged inside or outside a spacecraft.The thruster has a concentrator (36) for collecting particles (P).The shape of the concentrator is defined by a continuous contour (C1) wrapped around the thrust axis and is such that on a major portion of the contour, each section of the concentrator perpendicular to the contour has a parabolic shape and has a focus (F1) belonging to the contour (C1).In addition, the magnetic circuit (50) is arranged so as to generate the magnetic field (B) in the vicinity of the contour (C1).
