Working Principle of Reflex Klystron

A reflex klystron is a vacuum tube that produces microwave frequency oscillations through the interaction of an electron beam with an electromagnetic field. It consists of an electron gun, a resonant cavity, and an anode. The electron beam passes through the cavity, is reflected back by an repeller electrode, and interacts with the electromagnetic field again as it returns. This interaction causes the beam to bunch, and these bunches generate microwave oscillations.

Key Parameters Explained

  • Operating Frequency: The frequency at which the klystron operates, typically in the microwave range.
  • Anode Voltage: The voltage applied to the anode that accelerates the electron beam.
  • Beam Current: The current of the electron beam passing through the klystron.
  • Quality Factor (Q): A measure of the resonant cavity's quality, indicating how underdamped it is. Higher Q means less energy loss.
  • Power Output: The amount of microwave power produced by the klystron.
  • Efficiency: The ratio of output power to input power.
