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.
Journal ArticleDOI
Coaxial cavity gyrotron- recent experimental results
TL;DR: The feasibility of fabrication of coaxial cavity gyrotrons with an output power up to 2 MW, continuous wave (CW) has been demonstrated and information necessary for a technical design has been obtained.
