ABSTRACT:
Disclosed is a microwave tube with n (where n is an integer greater than one) parallel, longitudinal electron beams distributed on a ring centered on an axis XX'. The electron beams go through several groups of n cavities. So that each group may resonate on a single frequency, it is provided that the cavities of one and the same group will work in their dominant mode, at one and the same frequency, and will get excited in phase. To this end, the cavities of the input group are excited in phase by an appropriate device external to the tube. The device can be applied to multiple-beam klystrons working at high frequencies.
