Abstract
This study, as part of the researches on improving the performance of a Kaufman xenon ion thruster with beam jet diameter of 12 cm, investigated experimentally the effects of shapes and dimensions of the discharge chamber around the cathode on the discharge performance. The thruster was operated for test in varied discharge chamber shapes by means of changing the shapes and heights of the pole piece, the positions of the main hollow cathode, the cathode baffle diameters, and the intensity of the discharge electromagnetic field. As a result, it was found that with a pole piece without a collar, the ion generation cost was lower than that by the one with a collar, and the discharge voltage was higher, but only with a small difference. Increasing the diameter of the main cathode baffle resulted in higher discharge voltage. It was revealed that with collared pole piece, changing the baffle diameter produced a larger effect on the characteristic of propellant utilization efficiency versus ion generation cost than with non-collared pole piece. The optimal height for the pole piece is about 30 mm. 7 refs., 18figs., 2 tabs.
