Klystron is a Microwave Generator

Compare SLAC's large, high-power microwave generator (klystronGlossary Term - below) with this much smaller one (magnetron - right) from a typical microwave oven. magnatron.jpg (7942 bytes)

A klystron looks and works something like an organ pipe.

Organ pipe
Organ Pipe

 

In an organ pipe:

  • Blowing into the organ pipe produces a flow of air.
  • Flowing air excites vibrations in the cavity of the whistle.
  • The vibrations flow into the surrounding air as sound waves.
 

In a klystron:

  • The electron gun produces a flow of electronsGlossary Term.
  • The bunching cavities regulate the speed of the electrons so that they arrive in bunches at the output cavity.
  • The bunches of electrons excite microwaves in the output cavity of the klystron.
  • The microwaves flow into the waveguide , which transports them to the acceleratorGlossary Term.
  • The electrons are absorbed in the beam stop.
