Increasingly ambitious space missions rely upon the advancement of propulsion systems, and innovations in electric propulsion represent a vital step toward potential solutions. Electric propulsion research has indicated improved thruster performance at higher magnetic fields, but real-world implementations have been encumbered by available magnet technology. In this study, a new class of superconducting magnet designed for such space applications is demonstrated. A central cathode electrostatic thruster was paired with a conduction cooled high temperature superconducting magnet operated in non-pulsed mode. Using Xe propellant, thrust of 38–73 mN was measured at a central bore magnetic field of 1.13 T and on-anode field of 1.28 T, and the thruster's specific impulse was throttled between 1050s and 1450s. The peak thruster efficiency was 18.7%, inclusive of the power consumption of the magnet subsystems. This was performed without the onset of plasma instabilities, and is the first case in the literature of a high temperature superconducting plasma thruster operating at >1 T. [ABSTRACT FROM AUTHOR] |
