Web- Bunching action of a reflex klystron. The reflex klystron operates in a different mode for each additional cycle that the electrons remain in the repeller field. Mode 1 is obtained … WebFig. 1.6 – Draft of a reflex klystron structure, showing the repeller electrode and the single cavity with gap acting as buncher for electrons coming from the electron gun and as catcher for electrons pushed back by the repeller. Bunching occurs in the drift space, from the cavity to the vicinity of the repeller and back to resonator.

WebJan 5, 2024 · A klystron amplifier uses different cavities which control the electric field around the axis of the tube. A grid is placed in the middle of these cavities to allow the electrons to flow. The first cavity together with the coupling device is termed as a ‘Buncher’. 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.
