How does bunching occur in a reflex klystron
WebJan 31, 2024 · An electron which passes through the center of the buncher a little later, however, when the alternating voltage is increasing in the positive direction, has a higher net voltage acting on it. As a result, this electron … WebA simple way to produce a bunched beam is to pass a continuous beam through a chopper, where the beam is deflected across a narrow slit or a system of slits, resulting in a pulsed beam behind the slit. The chopper includes an RF cavity excited like the buncher cavity but with the beam port offset by a distance from the cavity axis.

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. WebThe voltage on the reflector must be adjusted so that the bunching is at a maximum as the electron beam re-enters the resonant cavity, thus ensuring a maximum of energy is transferred from the electron beam to the RF …

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’.
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. 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.
WebA reflex klystron consists of an electron gun, a cavity with a pair of grids and a repeller plate as shown in the above diagram. In this klystron, a single pair of grids does the functions …
