Abstract

Numerical investigations of electrodynamic systems (EDS) for experimental relativistic Backward Wave Oscillators (BWO) are made with help of computer codes based on linear theory methods. Dispersion diagrams for the nonaxisymmetric eigenwaves of the corrugated slow-wave structures (SWS) are calculated. Resonance properties of an experimental EDS containing finite length corrugated SWS, diaphragm cutoff neck and conical horn antenna, are investigated in detail. Frequency and starting current of generation are found for relativistic BWO based on such type of the EDS. The dependency of generation frequency with the electron beam voltage and cutoff neck location are investigated too. Obtained results are discussed and compared with known theoretical and experimental data.
