Abstract: | The design of a modulator that can produce high-voltage klystron drive pulses with minimal ripple on the top is described. The design study focused on ways to reduce ripple and adjust the shape of the pulse to minimize variations in the final output of the klystron. Comparisons of the pulse performance for a range of possible loads were done to determine the sensitivity of the design to load characteristics. The resulting modulator design incorporates dual pulse forming networks, and uses a cancellation scheme to reduce ripple. The basic design, simulations and the performance of a low-power prototype are discussed. A high-power klystron modulator design is summarized |
