TL;DR: In this article, a hybrid magnet system for fast frequency tuning (1 s) is presented, where a water-edge-cooled silicon nitride composite Brewster window with its thermal conductivity of k=60 W/mK, permittivity er=7.35°, and clear window aperture of 100 mm diameter, will allow long-pulse operation in the 1 MW power range.

TL;DR: In this paper, a telecommunication system can include a first section and a second section, where the first section can receive signals from at least one transmitting base station or transmitting terminal device, and the second section can extract signals from the combined frequency band.

TL;DR: In this article, the design of a 1.5MW, 140-GHz, TE-/sub 28,16/-coaxial cavity gyrotron is presented and results of experimental operation are given.

TL;DR: In this paper, a 1 MW, 140 GHz TE22,6 gyrotron with a built-in quasi-optical (q. o.) mode converter was used to demonstrate the usability of gyroron oscillators as frequency step tunable high power millimeter-wave sources.

TL;DR: In this article, a coaxial-cavity gyrotron operating in TE/sub 31,17/ mode at 165 GHz was presented, and the selection of the operating frequency and mode are based on the limitations imposed by the maximum held of the superconducting (sc) magnet at Forschungzentrum Karlsruhe, Institut fur Technische Physik (FZK).
