Klystron is a specialized linear-beam vacuum tube invented in 1937 by Russell and Sigurd Varian at Stanford University. It works by using an electron gun to produce a beam of electrons, bunching cavities to regulate the electrons into bunches, and an output cavity where the bunches excite microwaves. Klystrons can produce high microwave power and are used in applications such as radar, satellites, television broadcasting, medicine, and particle accelerators.

2. INTRODUCTION:A klystron is a specialized linear-beam vacuum tube (evacuated electron tube)The name klystron comes from the stem form κλυσ- (klys) of a Greek verb referring to the action of waves breaking against a shore, and the end of the word electron.The brothers Russell and Sigurd Varian of Stanford University are the inventors of the klystron. They invented it in 1937.

3. WORKING:The electron gun produces a flow of electrons.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 accelerator.The electrons are absorbed in the beam stop.
