Experimental Approach to improve Ion Thruster Performance: Part 2 Effects of magnetic Field

摘要

The effects of the magnetic field shape adjacent to the ion optics on ion thruster performance were investigated. In the experiments, the magnetic field configuration near The ion optics was varied by changing the direction of The downstream side-wall magnets in the radial and axial Directions. As a result, when the downstream side-wall Magnets were placed in the axial direction, the effective Ion beam extraction area was 10.2 /100 larger than when The magnets were in the radial direction.
