What is velocity modulation in klystron? - Answers

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.
