  • Patent number: 7897934
    Abstract: The invention relates to the fact that a common industrial neutron interrogation screening requirement is that a high throughput rate be accommodated by the screening system. The accumulation of elemental abundance ratio spectral data to minimize statistical uncertainty is a function of the neutron flux passing through the subject. If the subject passes through a neutron beam, with a strictly limited time window for exposure, the flux must be sufficient to accumulate the required statistics. The level of neutron flux necessary may exceed the cost effective limits of the selected neutron source means. Exposure time window dilation is disclosed through a class of system configurations which become practical for reduction to practice by utilization of linear neutron source topology neutron generators. This disclosure is concerned with example embodiments which utilize the length, width, thickness and segmentation of the source emission zone within an appropriate neutron source.

  • Publication number: 20080089460
    Abstract: The invention relates to a particle producing apparatus adapted to utilize a star mode of inertial electrostatic confinement of a glow discharge induced ion and neutral gas mixture of fusible low atomic number isotope species to generate protons or neutrons in a macro linear geometry, the apparatus comprising a hermetically sealed vessel of generally prismatic form having an inner surface and a central axis, within which vessel is disposed an elongate anode electrode structure surrounding an elongate cathode electrode structure having a perimeteral surface provided with apertures therein, the anode and cathode structures being substantially concentric along at least a part of their lengths and substantially coaxial with the vessel such that, during operation, the star mode beams of ions and high kinetic energy neutrals have a general direction of motion which is aligned substantially radially to a central axis of the vessel.

  • Patent number: 6171451
    Abstract: 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.

  • Patent number: 6121569
    Abstract: 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.
