Beam-wave Coupling in a Double-beam Gyrotron Traveling Wave Amplifier
A linear theory is used to study the beam-wave coupling in a double-beam gyrotron traveling wave amplifier (Gyro-TWA). Numerical results show that the beam-wave coupling in this type of amplifier excites six waves, which include one constant-amplitude backward wave, and five forward waves consisting of two growing waves, two decaying waves and one constantamplitude wave. The growing wave, whose growth rate is much larger than that of the other, has a larger operating bandwidth which is approximately the superposition of the interaction bandwidths of the two single-beams in the Gyro-TWA.
