Abstract: 

Nowadays there are a lot of research, aimed at creation of sources of electromagnetic oscillations in the submillimeter range. Along with the search for new methods of generation, the attention is paid to the possibilities involved into known generators with long-term interaction of electron beam with the electromagnetic fields produced by periodical structures (clinotrons and generators of diffraction radiation). The fineness of the elements of such generators are often wrongly considered as the main obstacle for the creation of such generators. On the basis of experimental study of clinotrons operating in the millimeter-wave range of generation, two reasons that hamper the effective generation clinotrons in the submillimeter wavelength region are shown: decrease of the current density of the electron beam in the vicinity of the surface of the periodic structure, and dispersion of geometrical parameters of the periodic structure.
Keywords: a layer of depleted electrons, clinotron angle, defects of the periodic structure, electron beam structure, exponential decay of the field, π-oscillations
