Research Abstract

The gyrotron with a long cavity continues to produce output radiation in the wide range of magnetic fields from 4.9 T to 5.2 T, and continuous frequency tuning in 6 GHz interval from 134 GHz to 140 GHz can be realized. Similiar type gyrotron in the submillimeter wavelength range was fabricated using a 15 T superconductive magnet. This gyrotron produced an output power larger than 10 W in the wide continously frequency range from 394.65 GHz to 396.27 GHz.
