Zusammenfassung:A magnetic pole structure for a Hall thruster. The magnetic pole structure comprises wide-envelope type outer magnetic pole components (1), a magnetic bridge (2), a pagoda-shaped inner magnetic pole component (3), an upper plate (4) and a bottom plate (7), wherein a plurality of wide-envelope type outer magnetic pole components are symmetrically distributed on the outer edge of the thruster with the pagoda-shaped inner magnetic pole component at the center to enclose a semi-open outer magnetic structure; the magnetic bridge is located between the wide-envelope type outer magnetic pole components and the pagoda-shaped inner magnetic pole component; the bottom plate is tightly attached to the bottoms of the wide-envelope type outer magnetic pole components and the pagoda-shaped inner magnetic pole component; and the upper plate is tightly attached to the upper portions of the wide-envelope type outer magnetic pole components. An outer magnetic pole expands in the circumferential direction, magnetic lines of for
