Abstract: Characterizing a cargo container and its contents. A system comprising an emitter to emit radio frequency (RF) energy, a receiver to receive an RF response related to the energy, and a processor operative to compare a plurality of RF responses. A method for characterizing a cargo container and its contents, the method including providing a system as described above, via the system: emitting a RF energy within a container, receiving an RE response of the container and the container contents, emitting second RF energy within a container, receiving a second RF response of the container and the container contents, and comparing the second RF response with the first RF response.

Abstract: A storage ring system and method for high-yield nuclear production of neutrons, isotopes and photons, include a particle supply for generating a beam of projectile or reaction particles, a closed storage ring for containing and recycling the projectile particles, an electron cooling system for stabilizing the projectile particles, and a target for initiating nuclear reactions with the projectile particles so as to generate the desired end-products, with improved efficiency and safety. The invention also provides a plurality of dipoles and/or trim magnets selectively situated around the ring to guide the projectile particles as they circulate within the system. Substantially trapped in the closed storage ring, the particle beam is recirculated inside the storage ring for repeated exposure to the target, until the particles either favorably react with the target or are lost through scattering.

Abstract: A radio frequency quadrupole (RFQ), which is a combination of the standard 4-vane and 4-rod designs, with a window or windows cut through mid-portions of the normally solid vanes. The windows decrease the resonant frequency, minimize undesirable mode coupling in the RFQ and result in a smaller and more easily tuned accelerator.

Abstract: A raster scan control system (18) for use with a charged-particle beam delivery system (20) provides precise control of large currents driving an inductive load. The beam delivery system includes a nozzle through which a charged-particle beam (24), such as a proton beam, passes prior to being directed to a target (32). The nozzle includes both fast and slow sweep scan electromagnets (204, 208) that cooperate to generate a sweeping magnetic field that steers the beam along a desired raster scan pattern at the target. The electromagnets are driven by large currents (213, 215) from the raster scan control system.
