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. WebJun 19, 2024 · Basic Operations: A high velocity electron beam produced by the accelerating anode is passed through a buncher cavity, drift space, catcher cavity and finally collected by the collector terminals.

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’. birds that sound like bob whiteWebThe 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 … birds that sing in the morning
