OPERATION
a. The operation of the multicavity klystron is similar to that of the two-cavity klystron. Notice in figure
10 that the multicavity klystron does not have a control grid. The number of electrons in the stream is controlled
by changing the cathode voltage. Also notice the absence of grids in the cavities. The large number of electrons
flowing and the high electron velocities would be seriously affected by the grids that are normally used in the
two-cavity klystron.
