Formula for Reflex Klystron Calculator

Where,

Vo – DC Beam Voltage

Io – DC Beam Current

f – Frequency of Operation

N – Mode of Operation

L – Repeller Spacing

A customized low-power vacuum tube called a reflex klystron is used to create oscillations at microwave frequency. Modulation of current and velocity is its underlying operating concept. Klystrons are essentially specialized tubes that are utilised in the microwave frequency range as oscillators and amplifiers. Main parameters for operation of reflex klystron is its output power denoted in watt, repeller voltage and the efficiency, all of these can be calculated using the above calculator.
