摘要:
A defense system and a method for discriminating between armed re-entry vehicles and unarmed objects which are in close proximity of each other. The re-entry vehicles and the unarmed objects are bathed in a cloud of relativistic electrons with the resulting signatures from heavy objects, i.e., re-entry vehicles, being imaged directly. Detectors sense the location and identify of the re-entry vehicles and passes this information onto a weapons platform for tracking and interception.
摘要:
An apparatus for amplifying coherent radiation at millimeter and submillimeter wavelengths includes the combination of a travelling-wave-tube cyclotron-maser-amplifier structure and a magnetron-injection electron gun. The amplifier structure includes a fast-wave drift tube and an electromagnetic wave launcher within the bore of a superconducting magnet. The magnetron-injection electron gun is also within the bore of the magnet and is coupled to the drift tube. As a travelling wave is launched in a preferred mode in the drift tube, the electron gun injects an annular beam of relativistic electrons having both large energy transverse to the axis of the device and small energy spread into the drift tube so that the electrons gyrate at their cyclotron frequency in orbits about the lines of the axial magnetic field produced by the magnet. The travelling wave is amplified by extracting energy from the relativistic electron beam. Efficiency of this energy transfer is optimized by tapering the magnetic field near the output end of the wave-beam interaction region.
摘要:
An electron beam and collective ion-electron beam accelerating apparatus inhich a relativistic electron beam and ions moving with it are accelerated in speed by passing them through a converging waveguide (i.e., a drift tube) of gradually decreasing diameter. The ions are separated from the electrons upon leaving the waveguide.
摘要:
A method of forming micro-components is disclosed. The method includes pretesting and conditioning of the micro-components. The micro-components that fail testing or conditioning are discarded, and those remaining are assembled into a panel.
摘要:
An improved light-emitting display having a plurality of micro-components sandwiched between two substrates is disclosed. Each micro-component contains a gas or gas-mixture capable of ionization when a sufficiently large trigger voltage is supplied across the micro-component by up to two triggering electrodes and ionization can be maintain by a sustain voltage supplied by up to two sustain electrodes. The display is further divided into a plurality of panels that can be individually addressed in parallel, preferably directly through the back of the panels and can include voltage multiplying circuitry to decrease the power demands for addressing circuitry. Alternative methods of addressing the micro-components include the use of directed light and arrangements of electrodes to address multiple micro-components with a single electrode.
