Аннотация:We compared the electromagnetic field profiles, mode structure and radiation frequency spectrum
for two types of slow-wave structure with continuous profile: sinusoidally corrugated and half-torus
on a pedestal. For two-sectional structure (two periodic section are separated with drift tube) we
matched section and drift tube length for the stable long-pulse generation with wide beam current
value range.
The conditions of the RDG generating frequency stabilisation were found to be related to the
longitudinal resonances of the SWS surface wave. The resonance bulk field excitation at the frequency
close to the critical one for the mode of equivalent smooth waveguide is shown to be an additional
agent for the generation power boost.
