    Abstract: A vacuum arc thruster with multi-layer insulation includes a housing, an anode unit and a cathode unit spaced apart from each other in the housing, and an insulator disposed between the anode unit and the cathode unit. The insulator includes a plurality of fuel layers and a plurality of insulating layers. Each insulating layer is located between every two adjacent fuel layers. Accordingly, a multiple-layer design is formed by arranging the fuel layers and the insulating layers which are made of different materials in an alternating manner, thereby attaining the maximum field emission effect, increasing the stability and efficacy of operating the vacuum arc thruster, and prolonging the service life of the thruster.

    Abstract: A magnetic multi-pole propulsion array system is applied to at least one external cathode and includes a plurality of magnetic multi-pole thrusters connected adjacent to each other. Each magnetic multi-pole thruster includes a propellant provider, a discharge chamber, an anode and a plurality of magnetic components. The propellant provider outputs propellant. The discharge chamber is connected with the propellant provider to accommodate the propellant. The anode is disposed inside the discharge chamber to generate an electric field. The plurality of magnetic components is respectively disposed on several sides of the discharge chamber. One of the several sides of the discharge chamber of the magnetic multi-pole thruster is applied for one side of a discharge chamber of another magnetic multi-pole thruster.
