摘要： The present invention is for a system and a method of VUV photoionization of fullerene and derivative clusters followed by their thermal effusion for a practical energy-efficient and economically-viable high thrust density ion thruster. By taking advantage of the state-of-the-art high intensity VUV photon sources, present invention is able to provide much softer ionization with minimal internal energy deposition than the ionization in the electron impact or charge exchange type ionization in plasma environment used in conventional ion thrusters. Because the invention eliminates the need of additional gas for forming discharge plasma, it permits simpler and lighter structures than the conventional fullerene thrusters with significantly enhanced propellant-usage efficiencies, thrust to power ratios, and thrust to weight ratios. Because the present invention employs softer VUV photoionization, it permits the usage of heavier and more complex fullerene derivatives, nanotubes, and nanotube derivatives than fullerene clusters for fuels without significantly fragmenting them.

摘要： A photon source includes a plasma source for generating plasma and a photon guide through which the plasma travels. The photon guide includes an inner surface configured for reflecting photons emitted from the plasma. As the plasma travels through the photon guide, plasma electrons and ions recombine at the inner surface, whereby the predominant species emitted from an outlet of the photon guide are the photons and neutral particles, with few or no plasma electrons and ions being emitted.

摘要： A propulsion system for spacecraft is based on an electric engine that expels propellant to achieve thrust. The propellant is first ionized to generate a plasma. Plasma particles are selectively accelerated via a pulsed laser that accelerates predominantly the electrons in the plasma. The electrons are expelled first, forming a space charge that acts as a virtual cathode to accelerate the positive ions. Interactions between the laser beam and plasma electrons are predominantly through the ponderomotive force.

摘要： A system for producing a charged particle beam from a photoionized cold atom beam. A vapor of neutral atoms is generated. From these atoms, an atom beam having axial and transverse velocity distributions controlled by the application of laser light is produced. The produced atom beam is spatially compressed along each transverse axis, thus reducing the cross-sectional area of the produced beam and reducing a velocity spread of the produced beam along directions transverse to the beam's direction of propagation. Laser light is directed onto at least a portion of the neutral atoms in the atom beam, thereby producing ions and electrons. An electric field is generated at the location of the produced ions and electrons, thereby producing a beam of ions traveling in a first direction and electrons traveling in substantially the opposite direction. A vacuum chamber contains the atom beam, the ion beam and the electron beam.
