Heater materials and geometry are analyzed to address the requirements of large lanthanum hexaboride hollow cathodes. Larger hollow cathodes are capable of increased discharge currents but require higher heater powers to ignite. Existing cathode heat

A promising new hollow cathode concept for high-power, long-lifetime electric thruster applications is explored using finite-element analysis to inform an experiment presently being constructed. This RF-Controlled Hollow Cathode concept adds radio-fr
