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.
