Development of a Radiofrequency Cathode for Hall Thrusters

Abstract

The development of radiofrequency (RF) cathodes for Hall thrusters marks a pivotal advancement in the realm of electric propulsion for space exploration. This paper describes the technological evolution and practical applications of RF cathodes as electron sources, elucidating their impact on enhancing the efficiency and reliability of Hall thrusters. The RF cathode's ability to generate and sustain plasma through radiofrequency principles offers notable advantages over conventional cathodes, including extended operational lifespan, reduced maintenance requirements, and greater adaptability to diverse propulsion demands. Through a comprehensive analysis of the RF cathode's design, performance metrics, and integration within Hall thruster systems, this study underscores the potential of RF cathodes to revolutionize space propulsion, supporting a new era of satellite technology and interplanetary missions.
