EVALUATE OFTHE ION BEAM BEHAVIOR OF RADIO-FREQUENCY ION THRUSTER

Abstract

Today, the application of satellite spatial propulsion using the practice of electric propulsion is quite common, including the success of the development of the hall and ion thruster. In 1884, Hittorf introduced for the first time a Radio Frequency Ion Thruster (RIT), which produced a plasma in a vacuum using a magnetic field. Inheriting his ideas and from the achievements of Applied Aerodynamics Research Laboratory, we study theoretical analysis Tool Development and measurement system. The system under research and development includes faraday probe, RPA probe and Torsional Thrust Stand with ion thruster and was tested with different input locations and conditions to evaluate the ion current density and ion energy distribution. The specifications of Faraday probe and RPA probe are designed based on the electronic density and temperature analysis, etc.
