How does bunching occur in a reflex klystron
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 WebDec 19, 2024 · The energy is coupled into the buncher and out of the catcher cavities with a small loop, which will contain some of the magnetic lines of force of the fields and will thus have a current induced in them.

WebThe bunching process in a two-cavity klystron is by no means complete, since there are large numbers of out-of-phase electrons arriving at the catcher cavity between bunches. Consequently, more than two cavities are always employed in practical klystron amplifiers.
WebThe faster electrons catch up with the slower electrons and bunching occurs. The electron- beam bunching already starts at the beginning of the helix and reaches its highest expression on the end of the helix. The electron bunches in the beam give up energy to the wire of the slow wave structure. They repel the electrons in the wire and ... northampton town fc x hartlepool united fcWebFig. 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.
