Abstract

A low-power tunable quasi-optical gyrotron was designed for driving free electron laser amplifiers in the frequency ránge of 220–270 GHz. The gyrotron cavity consisted of a spherical mirror and a plane slotted mirror to produce a Gaussian radiation output beam. Output powers of 1–10 kW were obtained in the 4 cm length cavity by a few amperes of electron beams with a voltage of 30 kV.
