Bunching in reflex klystron
WebGHz, and the RF source is a 25-MW pulsed klystron with 60-kW average RF output power. The accelerating structure, with a built-in bunching section, is a disk-loaded waveguide with constant-impedance operated in the 2 /3 mode. It is to be operated under the fully beam-loaded condition for high average power with the 6- s WebAns) When bunching process occurs in reflex Klystron, it is seen that when the electrons returns to the cavity in the second positive peak i.e 1¾ cycle.We can obtain the maximum power, hence it is called Dominant mode.
