Quasi-CW 0.5 MW - 118 GHz gyrotron for ECRH
A quasi-CW 0.5 MW 118 GHz gyrotron has been designed and constructed. The gyrotron operates in a TE(22,6) cavity mode and provides a Gaussian output mode. It is composed of a triode-type electron gun, an improved beam tunnel, a high-mode-purity low-ohmic-loss cavity with rounded transitions and an optimised non-linear uptaper, a highly efficient internal quasi-optical mode converter employing an advanced launcher together with one phase correcting and two beam shaping reflectors, a large collector with a beam sweeping magnet, and a horizontal RF output through a liquid nitrogen edge-cooled single-disk sapphire window.
