Systems and Methods for Cylindrical Hall Thrusters with Independently Controllable Ionization and Acceleration Stages Yevgeny Raitses, Nathaniel J. Fisch and Kevin D. Diamant (The Aerospace Corp.)

This invention provides cylindrical Hall thrusters with independently controllable ionization and acceleration stages. Decoupling the ionization and acceleration stages allows the cylindrical Hall thruster to operate with a variety of propellant gases, including those that may otherwise be difficult to ionize. Decoupling these stages also has the potential to broaden the operating envelope, improve efficiency, and result in a higher velocity exhaust for future spacecraft applications.
