摘要： Crossed-field switch device has a continuous elongated closed path active plasma discharge region between adjacent electrodes. A magnet produces a magnetic field at an angle to the electric field to define the elongated active region in the interelectrode space where glow mode discharge occurs. The electrodes and magnetic field are shaped so that the glow mode discharge in the active region is elongated.

摘要： A pollutant destruction system connects a capacitive corona discharge chamber in a self-resonant circuit with an inductive element. Intermittent energizing signals are furnished from a power supply to induce corona discharges within the chamber, with the resonant circuit responding to the energizing signals by initiating additional corona discharges between energizing signals in a highly energy efficient operation. One or more discharge chambers can be provided in the resonant circuit, with each discharge chamber comprising a dielectric enclosure with a distributed electrode outside and an elongate electrode inside the enclosure. The inner electrode can extend either along the chamber axis, or along the inner chamber wall for better support and heat dissipation. The energizing pulse frequency can be controlled in various ways, such as in response to a termination of corona discharges, an increase in the pollutant concentration or an acceleration of an engine whose exhaust is being treated, or the pulses can be applied at a fixed rate.

In a broadest sense, an electron beam is driven with an electromagnetic wave at said first frequency in a first stage, having a first spatial period, to cause bunching of the electron beam. The electrons in the beam are oscillated with a second stage, having a second spatial period, to generate electromagnetic wave power from said beam at the second frequency.In a specific embodiment, the second frequency is near a harmonic of said first frequency. And in a particular implementation, the first stage is provided by a free electron laser having a first wiggler with a first spatial period, the second stage is a second wiggler having a second spatial period and a drift region is disposed between the first and second stages.

摘要： A high voltage stable pulse power supply 10 which includes a first power supply 11, ; a first capacitor 12 ; connected in parallel with the first power supply, a first switch 13 mounted in parallel with the first capacitor 12. The switch 13 selectively connects the first capacitor 12 to a load 14 so that the first capacitor 12 may discharge therethrough. An anti-droop network 15 is connected in series with the first capacitor 12. The anti-droop network 15 cancels droop in the output of the first capacitor 12 as it discharges into the load 14.In a specific embodiment, the anti-droop network 15 includes an inductive element 42 connected in series with the first capacitor 12 which is charged just prior to the activation of the first switch 13. The inductor 42 provides energy to compensate for the droop in the energy supplied by the first capacitor 12. In a more specific embodiment, the first switch 12 is implemented with a Crossatron switch 31 and a modulating anode electron gun 32 to minimize system control voltages.The present invention achieves coherent emission in a free electron laser, for long pulses, allowing selection of single modes.

摘要： A blazed corrugated reflector having internal corrugations or vanes, blazed at specified design angles, coherently reflects power at specified wavelengths. The corrugations meet the criteria of effecting retroreflection according to the Bragg conditions for gratings, eliminating higher order modes of reflection, and maximizing retroreflection and minimizing forward scattering according to the blaze condition. Two such reflectors can be configured into a laser resonator by placing them at opposing ends of a matching waveguide. The reflector does not obstruct the passage of an axial electron beam, thereby making it suitable to implement the resonator portion of a free electron laser.

摘要： An auxiliary magnetic field coil is associated with the interelectrode space of a crossed-field switch device for ignition of the crossed-field switch device when high voltage is applied across the interelectrode space. The auxiliary magnetic field coil produces a localized field in which physical conditions cause conduction in the glow mode. Once conduction is started, the interelectrode voltage falls and with the main magnetic field applied to the entire effective interelectrode space, normal glow mode conduction takes place.

摘要： A steerable antenna comprising an array of T-shaped slots. The location of the slots is moved to define an array of ring- or spiral-patterned phase constant regions. Distortions or contractions of the pattern occur by repositioning some or all of the slots forming the array. The antenna also comprises an intermediate insulating layer and a lower plate. The insulating layer is formed by a deformable dielectric medium. Deformation of the dielectric medium allows the beam angle to be altered.

摘要： Dual band millimeter-wave and infrared anti-reflecting coatings are presented, which enhance the passage of millimeter-wave and infrared radiation into a substrate material. A substrate is coated with a quarter-wave coating of an infrared anti-reflecting material followed by a quarter-wave coating of a millimeter-wave anti-reflecting material followed by a second quarter-wave coating of an infrared anti-reflecting material. The second infrared anti-reflecting coating enables incident infrared radiation to pass into the millimeter-wave anti-reflecting material, while minimizing reflection. The first infrared anti-reflecting coating enables incident infrared radiation from the millimeter-wave anti-reflecting material to pass into the substrate material, while minimizing reflection. The millimeter-wave anti-reflecting coating enables incident millimeter-wave radiation to pass into the substrate material, while minimizing reflection. All of the materials used are chosen to be millimeter-wave and infrared radiation permeable. Because the wavelength size ratio of millimeter-wave radiation to infrared radiation is on the order of 1000:1, the millimeter-wave anti-reflecting coating does not interfere, to the first order, with the transmission of infrared radiation, and the infrared anti-reflecting coating does not interfere with the transmission of millimeter-wave radiation.
