RESPONSE OF KLYSTRONS TO NANOSECOND PULSES

Abstract

This investigation uses ballistic theory in the analysis of the behavior of an electron beam passing through alternate gap and drift regions, with the gap regions having excitation fields. The analysis develops the response to a complicated frequency spectrum of the drive signal. First the double frequency case is analyzed. Relativistic effects are taken into account and their influence on the current response studied. Then the theory is extended to the more complicated case of a Gaussian spectrum. The first-order bunching theory is used to plot current response curves. An estimate of the pulse distortion resulting from nonlinear elec tron beam dynamics is obtained from the curves. It is also of interest that the envelope shape of the exit current is almost completely in dependent of the r-f frequency. The large signal, finite-gap analysis is carried out, and the results extended to the multiple-cavity klystron.
