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

WebDec 13, 2015 · Abstract: Reflex Klystron Oscillator has been studied again to explore the effects of considering bunching parameter X greater than one. It is observed that as X exceeds unity, the relation between the departure time and the arrival time of the bunched electrons becomes as multivalued function and the Fourier component of the beam … 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.
WebJul 7, 2024 · Definition: A Reflex Klystron is a specialized low-power vacuum tube used to produce oscillations at microwave frequency. Its principle of operation is velocity and current modulation. Klystrons are basically specialized tubes used as amplifiers and … WebJul 31, 2024 · Electron Bunching The klystron utilizes a phenomenon called electron bunching which goes as follows: Electrons in a beam leaving a source at high velocity all …
WebAbstract: A comprehensive analysis of reflex klystrons is developed by considering the electrons as particles acted upon by forces which modify their motion. The analysis is … 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.
