Overview of the Field Reversed Configuration LorentzForce Propulsion Technology

Field reversed configuration Lorentz force propulsion technology uses a rotating magnetic field to drive plasma to generate field reversed configuration (FRC) and uses Lorentz force to accelerate it to generate thrust. Since this thruster does not use grid acceleration, there is no grid sputtering problem, which greatly extends the working life of the thruster. This technology draws on nuclear fusion technology, with high thrust density and a wide range of power levels, which is feasible for future deep space exploration for high specific impulse, high thrust and long-life propulsion systems. In this paper, the development of field reversed configuration Lorentz force propulsion technology is reviewed, and the working principle, calculation model and key problem are introduced. It provides a reference for plasma thruster technology in China.
