Varian reflex klystron: Electrons emitted from the heated cathode travel through the cavity grids toward the repeller plate and returned back through the grids. Self-sustaining oscillations develop, the frequency can be changed by adjusting the repeller voltage or changing the physical dimensions by squeezing the plates together
