How does bunching occur in a reflex klystron
WebIn a klystron the interaction between the input RF field and the electron beam causes velocity modulation and bunching of the electrons. The bunched beam, in turn, causes … WebThis is the Reflex Klystron Oscillator, which will now be described. The Reflex Klystron Oscillator is a low-power, low-efficiency microwave oscillator, illustrated schematically in Figure 11-8. It has an electron gun similar to that of the multicavity klystron but smaller. Because the device is short, the beam does not require focusing.
