Abstract :
Main results of experimental testing of the 140 GHz/1.5 MW coaxial gyrotron (Russian version of the joint Russian-German coaxial gyrotron) are summarized. Highly selective properties of the coaxial cavities and a possibility to increase considerably the efficiency of a coaxial gyrotron by applying independently an appropriate voltage on its electrodes (without any design modification) have been confirmed. A successful use of the two-potential connection scheme for the frequency step tuning and output power modulation in a coaxial gyrotron have also been demonstrated
