The gyrotron backward wave oscillator (gyro-BWO) is a promising source of coherent millimeter wave radiation based on the electron cyclotron maser instability on a backward waveguide mode (Fig. 1). The oscillation takes place as the forward moving electron beam and the backward wave form a feedback loop. Because of the cyclotron resonance nature of the beam-wave interaction, synchronism condition can be achieved in a fast-wave structure which possesses much greater power handling capability than conventional slow-wave structures. In particular, the gyro-BWO employs a non-resonant structure, hence the interaction can be electronically and magnetically tuned to cover a frequency band near the cut-off frequency where the small wave number provides large tolerance to the beam velocity spread.
