Abstract

The influence of the interaction between the electron beam and the fundamental harmonic of the traveling wave and the phase velocity inhomogeneity in the BWO on its efficiency was investigated both numerically and experimentally. The numerical simulation has shown that a single-step increase of the phase velocity along the interaction space improves the phase relationships between the HF current and electromagnetic field and increases the efficiency of the energy exchange to 70%. At the same time realization of the initial modulation of electrons in the traveling wave fundamental harmonic field solely, by shifting the corrugated structure from the beyond-cutoff neck, increases the efficiency of the homogeneous BWO to 40%. In the experiment carried out on the `SINUS-6' electron accelerator, a nonuniform-phase-velocity BWO operating with an efficiency of 45% and microwave pulse power of 500 MW and a homogeneous BWO with an efficiency of 30% have been realized.
