Millimeter Wave Vircator.
Abstract
Te millimeter wave vircator as achieved a frequency in excess of 39.9 Ghz and a peak power of the order of 21 kilowatts (f > or = 26.35 GHz) for a pulse duration of as short as 5 ns full width at half maximum. A new moderate voltage, high current density, field emission gun has been tested to a voltage, high current density, field emission gun as been tested to a voltage of 67 kV and an inferred current density of 7 kA/per sq cm. A new compact capacitive voltage monitor, similar to those commonly used in radar modulators, has been developed for short pulse, fast risetime, low to moderate impedance pulse lines. Keywords include: Virtual cathode, Virtual anode; Virtual cathode oscillator; VIRCATOR; Space-charge limit; Space-charge limiting current; Millimeter microwaves; and Spectrometer.
