WebCalculate the length of the cavity. Two Cavity Klystron Amplifier (4) A two cavity Klystron has the following parameters: Vo = 1000V Ro = 40KΩ, Io = 25mA f = 3GHz Gap spacing in either cavity, d = 1 mm Spacing between the two cavities, L = 4 cm Effective shunt impedance, excluding beam loading, Rsh = 30 KΩ. WebThe klystron is a linear beam device; that is, the electron flow is in a straight line focused by an axial magnetic field. The velocities of electrons emitted from the cathode are modulated to produce a density-modulated electron beam. The principle of operation involved here can be explained in terms of a two-cavity klystron amplifier.
