The propulsion team is responsible for the main engine, xenon fuel tank, and plumbing from the xenon tank to the main engine.
The engine works by ionizing Xenon atoms and repelling electrically charged plasma of Xenon. Xenon flows into the cathode; ions are captured in the keeper, and electrons are released. These electrons are ionized in the cone, and electrons gather on the anode. Plasma is released, providing thrust.
The plumbing system uses pressure release valves, pressure regulators, flow controllers, solenoid valves, and flow measurement devices to direct the flow of xenon to the cathode and the thruster.
