    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.

    Abstract: The klystron amplifier comprises an input cavity a plurality of intermediate cavities and an output cavity which are arranged along the path of an electron beam for focusing it, and an output waveguide coupled to the output cavity through a coupling opening. The product G.sub.0 (R/Q)Q.sub.ex is selected to be0.4.ltoreq.G.sub.0 (R/Q)Q.sub.ex .ltoreq.0.7where G.sub.0 represents the DC conductance of the electron beam, R/Q the characteristic impedance of the output cavity as defined at the gap between the edges of the drift tubes therein and Q.sub.ex the external Q determined by the size of the coupling opening.

    Abstract: In a velocity modulation tube comprising a floating prebuncher and at least one final prebuncher, frequencies of respective fundamental modes of resonance of the input cavity, the floating prebuncher, and the final buncher are adjusted to the lowest frequency of the passband of the tube, adjacent to the highest frequency of the passband, and higher than the highest frequency, respectively. Furthermore, the Q-value of the floating prebuncher is made equal to or lower than that of the input cavity. Naturally, the output cavity has its fundamental mode of resonance approximately at the center of the passband.

    Abstract: In a velocity modulation tube comprising at least one floating prebuncher resonator and at least one final floating resonator, in which at least one of the floating prebuncher resonators has a fundamental mode of resonance at a frequency lower than the center frequency of the operating passband of frequencies of the tube, the normalized length of the drift space placed downstream of each low frequency floating prebuncher resonator is made longer than the normalized lengths of the drift spaces located downstream of the other resonators and not longer than 90* in terms of the reduced plasma angle.
