This work presents XMET, a Xenon Microwave Electro-thermal Thruster. XMET uses a free-floating plasma discharge in a cylindrical resonant cavity operating at 2.45 GHz. It will be used as the RCS thruster for an integrated propulsion architecture for small GEO platforms, sharing common propellant and power systems with a gridded ion engine. We discuss the theoretical background of METs, previous work in the field and describe resonant cavity modelling and optimisation done for XMET. The XMET prototype design is explained, including the use of exchangeable nozzle insets produced in additive manufacturing. XMET is currently undergoing testing, including direct thrust measurements. |
