The results of the investigations of the electron flow in Grigor'ev-Shesterkin field-emission cathode cells intended for use in microwave tubes are presented. It is shown that it is possible to develop electron-optical systems (EOSs) with field-emission cathode matrices for O-type microwave tubes whose beam emittance is similar to the that of the EOSs with grids and hot cathodes. © 2014 Pleiades Publishing, Inc.

A procedure for designing filtering systems of high-power microwave electronic tubes is presented. A quantitative criterion of quality of tuning is given. In simulating a filtering system, it is proposed to use a prototype cavity with specified properties rather than a structurally complex active cavity. An implementation of the proposed procedure is shown using, as an example, a three-section filter of a multiple-beam klystron. © Pleiades Publishing, Inc., 2012.

A possibility to increase the interaction impedance of the klystron filtering system presented. Shows that replacement of a central bushing of circular cross section to elliptic in coaxial resonators associated with a filtering system, significantly improve the amplitude impedance gap. © 2014 IEEE.

Distortion of the gap impedance of the active cavity of a broadband multiple-beam klystron is investigated. A technique for averaging of the gap impedance in beam transport channels on the basis of calculation of the coordinates of the center of gravity of the real part of gap impedance function obtained by means of numerical simulation is proposed. © 2014 Pleiades Publishing, Inc.
