THE TIME INTEGRAL PROGRAM FOR OUTPUT SECTION OF BROADBAND KLYSTRONS

In this paper, we present a single period, one dimensional time integral model, with which we can calculate the energy exchange between the rf field and electrons in the output section of a klystron. We give a method by which the distance integral can be transformed simply into the time integral and the calculation of the space charge force of electron disks in the output section can be resolved.We write a program with DJS-6 type computer automation language, with which we calculate a C-band broadband klystron. It shows that the calculated resultsand the experimental ones are in good agreement. We also study the influence of the parameters of output section on the efficiency of the klystron.
