Abstract

In order to reduce the drawbacks, encountered in microwave electronic tubes, resulting from the presence of electrons reflected from the collector of these tubes towards the tube input, the invention provides for the collectors of these tubes to take the form of hollow bodies whose at least part of the internal volume exhibits an axis of symmetry not coinciding with the axis of the beam. This arrangement reduces the number of electrons liable to return towards the tube input and produces a spread in their phases. Application is made to klystrons.
