Abstract

A theory relating phase of the current modulation to the microwave phase is developed for the folded waveguide klystrons. The power transfer from the beam to microwave is described in terms of the propagation distance and phase shift (alpha) _n of the energy modulations launched at gaps. It is shown that the phase difference between the current modulation and the induced voltage at the gaps is essential for efficient power transfer from the beam's kinetic energy to microwave field energy. The optimum value of the phase shift for maximum power transfer from the beam to microwaves occurs at (alpha) _n equals -2, which may be useful for design of the folded waveguide klystron.
