Using a combination of experiments and simulations, this project will complete research on a novel technology for an electrically powered plasma thruster by delivering large thrust density without the need to expose electrodes to plasma, aiming at achieving longer lifetime, lower system complexity, and flexibility in terms of suitable propellants in comparison with existing flying technology. Over coming Electrode erosion and lifetime limiting factors by implementing an External Discharge system with novel-innovative neutraliser technologies, Innovative external discharge concepts have been implemented to improve lifetime and efficiency issues by moving the discharge external to the channel. Electric propulsion is supporting the new space economy by fulfilling mission requirements as primary propulsion units, giving access to both lower and higher orbits as well as longer useful mission lifetimes for interplanetary travel and deep space exploration. 

The experimental investigation addresses scientific and commercial needs by developing novel and innovative neutralisers to assist with testing of a alternative low power long lifetime cost-effective Hall thruster, the External Plasma Discharge Hall Thruster (XPT) operated with legacy and alternative propellants.
