To inspect numerical models for precise numerical analysis code development and to research ion thruster mechanisms (its discharge and ion beam optics behavior), a two-dimensional Kaufman-type visualized ion thruster was designed and fabricated. Its operations, probe measurements and spectroscopy measurements indicate that this thruster can visualize a schematic of ion production and extraction as described in conventional textbooks: ion beam extraction influences the ion density distribution in most of the discharge chamber; a close correlation exists between the ion beam focus position and the appropriate beam optics.
