Abstract

Summary form only given. The Gyrotron Backward-Wave Oscillator (Gyro-BWO) characterizing broadband continuous tuning is a high-power source of coherent millimeter wave radiation based basing on the electron cyclotron maser instability. This study proposes a Ku-band TE₀₁ fundamental harmonic Gyro-BWO. First, it calculates the start oscillation frequency and length according to the linear theory of Gyrotron. Second, the beam-wave intersection efficiency and output power are obtained making use of the nonlinear self-consistent equations. The parameters indicate that beam voltage V=70KV, electron transverse and longitudinal velocity ratioα = 1.5, guiding magnetic field B=1.12B_g, operating current I_b= 10A.
