Abstract: An FEL array is comprised of adjacent FEL modules. Each module preferably uses a ribbon beam plasma-anode E-gun (PAG) or another plasma-assisted E-gun to produce a planar E-beam that interacts with a planar wiggler magnetic field. The modules may share a common electron gun. A control signal is input through a phase priming array to preselect the radiation mode. A planar, distributed Bragg resonator/reflector is used to set up a high-Q cavity, enabling the low gain module to produce high power radiation. The FEL modules are arranged in an array to reduce the output radiation flux density while achieving high output power density in the far-field, and to permit beam steering by phase control of individual modules. The relatively low current density of the individual E-guns lessens the size of the guiding magnetic field in each module to the extent that the wiggler magnetic field alone is sufficient to perform this guiding function.

Abstract: A method of optimizing the design of waveguide reflector surfaces for high-Q cavities. The method assumes ideal conducting surfaces and proceeds from simple planar waveguide systems which are compatible with resonant standing waves to the development of the allowable surfaces which are necessary to contain the standing waves in a finite system. Apparatus constructed in accordance with the method achieves a Q in excess of 10,000.

Abstract: A plasma-anode electron gun includes a cathode means of a material such as molybdenum having a relatively high ratio of emission of secondary electrons to impinging helium ions. A hollow annular anode structure (16) contains an ionized plasma, and has a central opening (38) through which the electron beam (36) is directed, when ions from the anode are released to impinge upon the cathode (12). The anode and ion source structure may be grounded, and ions are released through openings facing the cathode when a positive trigger pulse is applied to one or more electrodes extending within the plasma. The cathode is preferably operated at a voltage in the order of thirty to two hundred thousand volts negative with respect to the cathode. Leakage of ions from the hollow anode may be inhibited by the provision of a supplemental grid biased to a low positive potential.

Abstract: A crossed-field switch device is connected in parallel to a load device which may arc. The characteristics of the crossed-field switch device are that it will not conduct when a high voltage is applied, but when the load device arcs, the crossed-field switch device conducts, taking current from the arc so that the arc quenches. The crossed-field switch device thus is a crowbar which is automatically conductive when the applied voltage decreases due to a line or load short.

Abstract: 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.

Abstract: A method is disclosed of employing free electron lasing action at a first frequency to achieve gain in output power at a second frequency. 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.
