HG ion thruster component testing [PDF]
14th International Electric Propulsion Conference, 1979 Electron bombardment thrusters, under development to provide both auxiliary and primary propulsion functions for a large variety of space missions are tested. Thruster design verification which requires life tests of durations of the order of the time anticipated in space applications, are discussed.

Molecular propellants for ion thrusters
Plasma Sources Science and Technology, 2019 Abstract There is no ideal atomic propellant for ion thrusters. Xenon commonly used as propellant becomes resource-critical in light of electric propulsion commercialization. Combining these considerations leads to seeking alternatives to xenon as propellant.
