| 20090153015 | SELF-REGENERATING NANOTIPS FOR LOW-POWER ELECTRIC PROPULSION (EP) CATHODES - Spindt-type field-emission cathodes for use in electric propulsion (EP) systems having self-assembling nanostructures that can repeatedly regenerate damaged cathode emitter nanotips. A nanotip is created by applying a negative potential near the surface of a liquefied base metal to create a Taylor cone converging to a nanotip, and solidifying the Taylor cone for use as a field-emission cathode. When the nanotip of the Taylor cone becomes sufficiently blunted or damaged to affect its utility, the base metal is re-liquefied by application of a heat source, a negative potential is reapplied to the surface of the base metal to recreate the Taylor cone, and a new nanotip is generated by solidifying the base metal. | 06-18-2009 |

| 20150076987 | Robust, Flexible and Lightweight Dielectric Barrier Discharge Actuators Using Nanofoams/Aerogels - Robust, flexible, lightweight, low profile enhanced performance dielectric barrier discharge actuators (plasma actuators) based on aerogels/nanofoams with controlled pore size and size distribution as well as pore shape. The plasma actuators offer high body force as well as high force to weight ratios (thrust density). The flexibility and mechanical robustness of the actuators allows them to be shaped to conform to the surface to which they are applied. Carbon nanotube (CNT) based electrodes serve to further decrease the weight and profile of the actuators while maintaining flexibility while insulating nano-inclusions in the matrix enable tailoring of the mechanical properties. Such actuators are required for flow control in aeronautics and moving machinery such as wind turbines, noise abatement in landing gear and rotary wing aircraft and other applications. | 03-19-2015 |

The device has an envelope with a transparent face, the face having an interior surface coated with a cathodoluminescent screen and a thin, reflective, conductive, anode layer. There is a broad-beam electron gun mounted directly to feedthroughs in a base of the envelope with a heated, button-on-hairpin, cathode for emitting electrons in a broad beam towards the anode, and a power supply mounted on the feedthroughs at the base of the envelope that drives the cathode to a multi-kilovolt negative voltage. A two-prong snubber serves as an anode contact to permit the power supply to drive the anode to a voltage near ground.

| 20130082586 | ELECTROSTATIC PARTICLE INJECTOR FOR RF PARTICLE ACCELERATORS - A method and a device for injecting charged particles into the first cavity resonator of an RF particle accelerator are provided. A n electrode is provided at the entrance to the first cavity resonator, which electrode is connected to a DC voltage source and generates a potential well that accelerates the particles leaving an ion source towards the first cavity resonator. As a result of the ion source and the accelerator path, i.e., more particularly the cavity resonators of the accelerator path, lying at a common potential, more particularly earth potential, the electrostatic potential well does not contribute to the overall energy of the particles, the overall acceleration effect is brought about by voltage induction in the RF resonator and the DC voltage source is not loaded by the beam current, and so the latter need not be precisely regulated or powerful. | 04-04-2013 |
