Abstract

Two high power, high frequency magnicons have recently been developed by Omega-P, Inc. The first tube, a frequency-doubling amplifier at 11.424 GHz, was designed and built in collaboration with the Naval Research Laboratory (NRL), to be the prototype of an alternative to the klystron for the Next Linear Collider (NLC); its current use is to furnish RF power for tests of high power components, active pulse compressors, and accelerating structures. The tube is designed to produce ∼60 MW, in ∼1.2 μsec pulses at 58% efficiency and 59 dB gain using a 470 kV, 220 A, 2-mm-diameter beam. Operation of this magnicon has established a research facility at NRL which is only the second laboratory in the USA where high-power microwave R&D at X-band can take place. The second tube is a third harmonic amplifier at 34.272 GHz, with a design power of ∼45 MW in ∼1 μsec pulses at >40% efficiency and 54 dB gain. Its beam voltage is 500 kV, beam current is ∼220 A, and beam diameter is ∼1 mm. This tube, which is now in operation at Yale University, is designed for developing RF technology in the millimeter wavelength domain for a future high-gradient multi-TeV electron-positron linear collider. Design features and latest experimental results for these two magnicons are presented in this paper.
