About

Dale A. Robinson is a distinguished researcher in electric propulsion, with a primary focus on the development and characterization of hollow cathodes for high-power Hall thrusters. His most notable contribution is his work on the HERMeS (Hall Effect Rocket with Magnetic Shielding) 12.5 kW thruster, a critical component for NASA’s Asteroid Redirect Robotic Mission. Robinson’s research has advanced the understanding of cathode emitter materials, particularly comparing barium oxide-impregnated and lanthanum hexaboride emitters through rigorous wear-testing, performance characterization, and plasma modeling. His 2016 paper on this topic, with 8 citations, has provided foundational insights for optimizing cathode longevity and reliability in deep-space missions. Robinson’s work bridges experimental validation and computational modeling, directly impacting the design of next-generation propulsion systems. His achievements include contributing to NASA’s ambitious space exploration goals, demonstrating the practical application of his research in mission-critical hardware. For students and researchers, Robinson’s work exemplifies how detailed component-level studies can enable transformative space technologies, making him a key figure in the field of electric propulsion.
