摘要：
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.
