Question

Derivation of velocity modulation in reflex klystron.

Answer 1

Answer:

As variations in the velocities of electrons in the electro beam is called velocity modulation

Answer 2

Answer:

So, working principle of reflex klystron is velocity and current modulation. So, electron beam is injected from the cathode and that injected beam travel with a uniform velocity till the cavity. And in the cavity gap, the velocity of the electrons is modulated.

Explanation:

What is velocity and current modulation in a reflex klystron? Ans. Variation in velocities of the electrons in the electron beam is called velocity modulation variation in the current density of the electron beam is referred to as current modulation.
