The analysis of the static potential distribution in a cross-section of an equipotential cylindrical channel with a tubular electron beam has been performed for both symmetric and eccentric arrangements of the electrodes. It has been shown that a gradual change of the channel width does not allow for the formation of an effective natural ion trap in the azimuth direction.

It is shown, that in single-stage devices efficiency more than 30% on the first harmonics of cyclotron frequency and 20% on the second harmonics, in two-cascade devices respectively 60% and 50%, are achieved. Whereas in considered devices there is no effect of a dynamic stratification of a beam, their power in essence is not limited in SHF band.

Consideration to an application of surface magnetostatic waves in ferrite films for the creation of microwave band-pass filters is given. Experimental samples of single-channel filter with insertion losses at the center frequency of less than 2.5 dB are discussed. The filter center frequency and bandwidth can both be tuned independently. Specifications of frequency channelizers are shown.

Electron motion in an undulator magnetic field formed by straight magnets with alternating polarity placed in parallel is studied in this work. In the mathematical model the magnets are simulated as dipoles. It is shown with a high degree of accuracy that the dipole field is chaotic, which causes frequent shifts in the direction of the electron motion and occurrences of braking radiation. The well-known Ginsburg formulas were used.
