WebThesis Research: Performance and Plume Characterization of a Laboratory Krypton Hall Thruster Coursework: Computational Methods for Engineers (computational PDEs, CFD), ... WebKrypton is a lower cost propellant than xenon, and with a higher ionization potential is a less efficient propellant. Thrusters running on krypton tend to experience higher erosion, and have slightly higher Isp at comparable powers at the cost of less overall thruster efficiency. Iodine as a propellant is being pioneered by Busek.

WebTypical krypton thruster efficiency was 70 percent at a specific impulse of approximately 5000 s, with a maximum demonstrated thrust-to-power ratio of approximately 42 mN/kW at 2090 s specific impulse and 1580 watts input power. WebKrypton is an attractive Hall thruster propellant because it shares similar properties to xenon, perhaps more so than any other alternatives. It is also an inert noble gas, but it is approximately ten times less expensive than xenon. In most of the present electrostatic thrusters designed for xenon propellant, switching to krypton propellant would WebDue to the relative high price and scarcity of xenon and the superior specific impulse of krypton, krypton has recently sparked interest in the electric propulsion community. The higher specific impulse could extend Hall thruster use to a larger range of mission applications. Although previous studies3-7 report krypton to have an inferior foals manchester
