چکیده
* Work supported by the US Department of Energy. In this paper we consider the preliminary designs of three-cavity microwave circuits for coaxial gyroklystrons. These tubes are predicted to produce over 100 MW of power in 1 μs pulses in Xand Ku-Band for linear collider applications with efficiencies exceeding 40% and gains above 50 dB. In particular, we examine the effect of first and second harmonic buncher cavities on the efficiency and gain of both first and second harmonic microwave circuits. We also examine the necessary conditions to contain the axial field profile of overmoded buncher and output cavities. Performance is contrasted with current two-cavity designs. [1]

Initial Operation of the Maryland Coaxial Gyroklystron Experiment
We describe results from the initial operation of our coaxial gyroklystron experiment, which is being evaluated as a potential driver for future linear colliders. The interaction is designed to occur between a 500 kV, 500 700 A beam and a series of coaxial TE0n1 microwave cavities. Output powers in excess of 100 MW at 8.568 GHz are expected with an efficiency of about 40% [1]. We detail perform...

In this paper we consider the design of a four-cavity microwave circuit for a high-gain K-band gyroklystron. The goal is to use this device to test a high gradient linear accelerator structure. The frequency doubling circular gyroklystron uses a beam voltage of 500 kV, beam current of 200 A in the circular TE011 mode and provides an output in the TE021 mode. We study the behavior of the four-ca...

In the present paper, a generalized self-consistent single mode linear analysis of gyroklystron has been presented. The analysis has been used to estimate and optimize the electronic efficiency of the gyroklystron device. The efficiency contours, necessary for the preliminary design of a gyroklystron, have been drawn by solving the coupled equations using Runga-Kutta method for the various devi...
متن کاملPlasmonic coaxial waveguide-cavity devices.
We theoretically investigate three-dimensional plasmonic waveguide-cavity structures, built by side-coupling stub resonators that consist of plasmonic coaxial waveguides of finite length, to a plasmonic coaxial waveguide. The resonators are terminated either in a short or an open circuit. We show that the properties of these waveguide-cavity systems can be accurately described using a single-mo...

A four cavity W-band gyroklystron amplifier experiment is currently underway at the Naval Research Laboratory. The gyroklystron has produced 67 kW peak output power and 28% efficiency in the TE011 mode with a 55 kV, 4.3 A annular electron beam. The full width half maximum (FWHM) bandwidth is greater than 460 MHz. Small signal and saturated gains of 36 dB and 29 dB, respectively, have been obser...
