Abstract (en)
[origin: EP1460267A1] A thruster has a chamber (6) defined within a tube (2). The tube has a longitudinal axis which defines an axis (4) of thrust; an injector (8) injects ionizable gas within the tube, at one end of the chamber. A magnetic field generator with two coils (12, 14) generates a magnetic field parallel to the axis; the magnetic field has two maxima along the axis (4); an electromagnetic field generator has a first resonant cavity (16) between the two coils generating a microwave ionizing field at the electron cyclotron resonance in the chamber (6), between the two maxima of the magnetic field. The electromagnetic field generator has a second resonant cavity (18) on the other side of the second coil (14). The second resonant cavity (18) generates a ponderomotive accelerating field accelerating the ionized gas. <??>The thruster ionizes the gas by electron cyclotron resonance, and subsequently accelerates both electrons and ions by the magnetized ponderomotive force. <IMAGE>
