WebIn this klystron, a single pair of grids does the functions of both the buncher and the catcher grids. The main difference between two cavity reflex klystron amplifier and reflex klystron is that the output cavity is omitted in reflex klystron and the repeller or reflector electrode, placed a very short distance from the single WebHow does bunching occur in a reflex klystron? A reference electron passing the gap when the gap voltage is zero travels with no change in velocity. An electron leaving the gap earlier during slightly positive voltage would travel further into repeller space and hence would take longer time then the reference electron to return to the gap. butcher joseph \u0026 coWebHow does bunching occur in a reflex klystron?
