  7. 10. Design, production, and validation of a vacuum arc thruster for in-orbit proximity operations

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Cornelis Peter Hiemstra; [2022]
    Nyckelord :vacuum arc thruster; propulsion; thrust measurement;

    Sammanfattning : Vacuum arc thrusters offer a relatively simple and cheap form of satellite propulsion, especially suitable for nanosatellites such as CubeSats or even smaller. This thesis focuses on vacuum arc thruster design considering the thruster’s manufacturing, assembly and integration into the spacecraft, and proposes a new anode geometry easing thruster production.
