A device (100) for producing fullerenes includes an IEC vacuum chamber (110) which has a central grid-like electrode (112) and a conductive outer shell (111) that are connected to a pulsed source of high voltage (114) and provide an electric field within the chamber (110). The applied voltage supports the creation of a plasma at the inner core of the chamber near the electrode (112). A carbon-based gas, which is introduced into the chamber (110), possibly along with an inert buffer gas, id dissociated into component carbon and hydrogen ions that are separated and the carbon ions recombined into fullerenes that appears as a soot. The device (100) includes a soot extraction mechanism for removing and collecting the fullerenes.

An electrostatic ion jet source design, based on inertial electrostatic confinement technology. According to the invention, the inertial electrostatic confinement jet source employs a configuration that is compatible with the generation and acceleration of ions within a vacuum chamber. The device uses a unique spherical configuration, enlarged hole grid, channel guide grid and electron production/confinement method. The prior art designs have to produce a small diameter jet. Virtual cathode formation in a high-density region, combined with a locally distorted cathode grid potential field, extracts accelerated ions in an intense quasi-neutral ion jet. The device ejects matter with a jet form for use as an industrial plasma spray, industrial material processing, waste treatment, welding or cutting materials, or for plasma vapor deposition. The invention also concerns a device that can provide a propulsive thrust force for spacecraft propulsion, particularly an ion jet thruster, which uses an inertial electrostatic confinement design having a discharge plasma for generating ions that provide thrust when accelerated and expelled from the device in the plasma jet.

A pneumatic safety system for a nuclear reactor includes a containment vessel containing He.sub.3 at high pressure communicating with a nuclear core by way of a conduit system which includes hollow pipes situated adjacent rods of fissionable material inside the core area. A rupturable diaphragm is interposed in the conduit system and is connected by a plurality of heat-pipes to the core area. The heatpipes respond to changes in core temperature and at a critical temperature cause the diaphragm to rupture thus allowing neutron absorbing gas under high pressure to quickly flood the core shutting down the nuclear reaction.

摘要:
An apparatus and method for supporting and agitating a plurality of loose objects during a procedure known as sputter coating. A magnetron gun and the apparatus are positioned within a vacuum chamber. The magnetron or sputtering gun produces a metal ion fog or vapor within the chamber which freely penetrates through screen mesh surfaces of a suspended basket of the apparatus containing the objects to be sputter coated. A solenoid or other suitable device vibrates the basket, agitating, and repeatedly momentarily suspending and reorienting the objects to achieve a very uniform metal layer being applied atop the objects. By changing the magnetron target or by using multiple magnetron, thin layers of multiple metals or layers with metal mixtures are also achievable with this technique.

Techniques to form dislocation cores along an interface of a multilayer thin film structure are described. The loading and/or deloading of isotopes of hydrogen are also described in association with core formation. The described techniques can provide be applied to superconductive structure formation, x-ray and charged particle generation, nuclear reaction processes, and/or inertial confinement fusion targets.
摘要:
One embodiment of the present invention includes a technique of performing a catalytic oxidation reaction at an anode to provide hydrogen ions from molecular hydrogen and a catalytic reduction reaction at a cathode to provide hydroxyl ions from liquid hydrogen peroxide. Passage of the molecular hydrogen to a reaction region is impeded with a proton exchange membrane and passage of the hydrogen peroxide to the reaction region is impeded with an ion-selective arrangement. Electric potential is generated between the anode and the cathode to provide electric power from a reaction of the hydrogen ions and the hydroxyl ions in the reaction region. In one variation, a regeneration technique is also provided.
摘要:
A high-perveance steady state deuterium ion gun was developed using a magnetic-index resonator in an Inductive Coupling Radio Frequency (ICRF) configuration. This approach made it feasible to generate an ion beam within millimeter dimensions extracted by negative potential placed at several centimeters from the exit of the ion source. The ion gun allows high extraction efficiency and low beam divergence as compared to other approaches.
