High Efficient Gyrotron-Based Systems for Materials Processing

Abstract

In parallel with the materials science research, an improvement of the equipment designed purposely for microwave processing of materials takes place. Among the most important specific features of the mm-wave processing are effective heating of low-loss materials, capability of both uniform heating of large-size specimens and local surface heating by intense wave beam, improved stability against thermal runaway. A line of gyrodevices ranging in frequency from 24 to 83 GHz with the output power from 3 kW to 35 kW CW, and a series of the gyrotron-based systems tailor-made for high-temperature processing and for powering electron cyclotron ion sources have been developed jointly by the Institute of Applied Physics and Gycom Ltd., (Nizhny Novgorod, Russia).
