Particle Radiation, E.g., Electron Beam Radiation (epo/jpo) Patents (Class 588/305)
  • Patent number: 8279994
    Abstract: Disclosed is a tokamak reactor. The reactor includes a first toroidal chamber, current carrying conductors, at least one divertor plate within the first toroidal chamber and a second chamber adjacent to the first toroidal chamber surrounded by a section that insulates the reactor from neutrons. The current carrying conductors are configured to confine a core plasma within enclosed walls of the first toroidal chamber such that the core plasma has an elongation of 1.5 to 4 and produce within the first toroidal chamber at least one stagnation point at a perpendicular distance from an equatorial plane through the core plasma that is greater than the plasma minor radius. The at least one divertor plate and current carrying conductors are configured relative to one another such that the current carrying conductors expand the open magnetic field lines at the divertor plate.

  • Patent number: 8232443
    Abstract: Method and device for inactivating a microbiologically contaminated mass containing solid particles. The method includes mixing the mass containing solid particles with a gelatinizing agent, transporting the mixed mass of solid particles and gelatinizing agent through a shaping device structured so that the mixed mass, at least in one area, is shaped to form a lamellar volume with a layer thickness of between 1 mm and 3 mm, and impinging the formed lamellar volume of the mixed mass with accelerated electrons.

  • Publication number: 20120123181
    Abstract: A system and method is provided for increasing interaction between seed particles in a seed cloud and target particles to be neutralized, detected or knocked down to the ground. This is achieved by applying a charge to the seed particles so that the seed cloud formed by release of the seed particles at altitude is highly charged, which in turn produces a strong electric field between the seed cloud and ground. The relatively strong electric field causes the seed particles to move downward (toward the ground) at a velocity sufficient to increase interaction (collisions) between the seed particles and the target particles.

  • Patent number: 7198750
    Abstract: The present invention is for a spore collection apparatus and its method of use. The portable spore collection apparatus includes a suction source, a nebulizer, an ionization chamber and a filter canister. The suction source collects the spores from a surface. The spores are activated by heating whereby spore dormancy is broken. Moisture is then applied to the spores to begin germination. The spores are then exposed to alpha particles causing extinction.
