摘要： The combination of a photoconductive switch coupled to an energy storage ice wherein the switch is comprised of photoconductive semiconductor material while the energy storage device comprises a radio transmission line including a different material, i.e. a dielectric storage medium. A photoconductive semiconductor gallium arsenide switch is embedded in a circular disc of dielectric material with upper and lower layers of continuous radial metallization configured in a circular pattern located thereon. The upper layer of metallization includes an apertured grid adjacent one surface of the switch, while the outer conductor of a coaxial output signal line is connected to the metallization layer on the opposite side with the inner conductor thereof passing through the dielectric layer to the undersurface of the semiconductor switch. A variation comprises the upper and lower metallization layers being formed in the shape of a plurality of discrete straight line segments or strips which extend radially outward from the center and thus forms a quasi-radial structure.

摘要： An electromagnetic railgun launcher and armature. The armature is made from superconducting material and is levitated between the rails of the launcher by the Meissner effect. The Meissner effect is created by cooling the armature and subjecting it to a magnetic field. The armature configuration has a closed loop topology and defines two planes - one plane coincides with the plane of the rails; the other plane is oblique to the first. The armature configuration, when placed between the rails receives an unbalanced Lorentz force which accelerates the armature.

摘要： An electromagnetic railgun. The device features two electrically connectedarallel rails. One end of each rail may be connected to a D.C. voltage source. At least one of the rails has a hole for closely receiving a metallic projectile. When the projectile is within the hole and the voltage is applied, currents flow through the two rails. Interaction of the currents with the self generated magnetic field causes a repulsive force between the two rails and launches the projectile outward from the rails.

摘要： A traveling wave type amplifier. The device features a pair of short helical input and output couplers through which an electron beam is projected. Application of an RF signal to the couplers serves to modulate the electron beam. A drift tube to be positioned between the couplers is dimensioned to attenuate the RF signal while permitting the modulated electron beam to pass through. An amplified output signal is extracted from the output helix. Gain of the tube is enhanced by a linearly decreasing magnetic focussing field.

摘要： This disclosure relates to a microwave amplifier (22) having an active X-Band microwave cavity (33) for use in electron paramagnetic resonance (EPR) measurements on large, lossy, irradiated, samples such as a human finger. The amplifier comprises an input section (31), a drift section (32) and an output section (33) which is the aforementioned active microwave cavity. An electron beam is used to input RF energy into the cavity. The input and output section have small helical couplers (34) for coupling RF energy onto and off of the electron beam. The RF wave is essentially "trapped" in the cavity because of the non-reciprocal nature of the electron beam medium and because the guide (i.e., drift section) at the input to the cavity has dimensions such that the frequency of the RF microwave energy is below the guides lower cut-off frequency. Also, a frequency "locking" effect occurs in the output cavity. The input frequency can be varied from 1-2% yet the output frequency does not change. The active microwave cavity has a cylindrically shaped window (41) located at the back-end of the cavity which extends inward towards the region of high RF fields inside the cavity. A large, lossy, irradiated sample such as a finger can be inserted into or behind this window and analyzed for radiation damage.

摘要： A transverse field interaction multi-beam amplifier device comprising a structure having, for example, a plurality of discrete cathodes cylindrically located in succession along a central axis of RF propagation. In registration with the cathodes are a respective number of annular collectors located within an outer cylinder which also acts as the structure housing. Intermediate the cathodes and collectors are two additional coaxial cylinders, one having a relatively smaller diameter than the other, with the smaller diameter cylinder including respective number of discrete grids, while the larger cylinder comprises a structure preferably having a rippled or undulating slow wave wall surface and a respective number of annular slots formed therein. The cathodes emit radial beams of electrons which pass through and are bunched by the grids and then accelerated by the slots to the collectors while interacting with and being modulated by an input RF beam propagating along the central axis of the coaxial structure between a first pair of cylinder walls including the grids and cathodes and inducing an output beam in a second pair of cylinder walls including the slots in the slow wave wall surface and the grids.

摘要： A photon triggered RF radiator having separate sections to perform the eny storage and the energy radiation functions. The energy storage function is performed by at least one charging electrode positioned on the upper surface of a photoconductive dielectric substrate, whereas the energy radiation function is performed by a charging electrode positioned adjacent to the charging electrode on the upper surface of the substrate. The charging electrode and the radiating electrode are separated by a predetermined gap distance that is large enough to insure there is no surface flashover between the electrodes and small enough to insure the efficiency of energy discharge from the charging pad to the spiral antenna is maximized.
