Propulsive Capability of an Asymmetric GDM Propulsion System [PDF]
42nd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2006 *† The role of the ambipolar potential in the propulsive capability of the Gasdynamic Mirror (GDM) has been studied previously. The electrostatic potential arises as a result of the initial rapid escape of the electrons due to their small mass, leaving behind an excess of ions and creating a positive electric potential that slows down the electron ...
