Abstract

We present the design of two continuous tunable CW coaxial cavity gyrotron oscillators, one of 330 GHz - 200 W with a bandwidth of 3 GHz for scientific applications and one of 30 GHz-150 kW with a bandwidth 0.4 GHz for industrial applications. The tuning of both gyrotrons is achieved by moving the tapered inner conductor in the axial direction and by adjusting the operating magnetic field.
