Abstract

The bandwidth of a klystron output cavity scale (approximately) as...^0.8P0.2, where p is the beam perveance and P is the beam power. For high-perveance (p > 10 (mu) pervs), high-power (P > 10 kW) electron beams, it is relatively straightforward to design a broadband output cavity. However, the design of the input cavity of the broadband klystron is more difficult. The purpose of the input cavity is to produce a velocity-moldulated electron beam with a frequency-dependant modulation amplitude that will optimize the bandwidth of the entire klystron system, while providing a large enough magnitude of velocity modulation to minimize the length of the klystron. This paper shows how a multiplet (multiple cavity) buncher cavity can be designed to provide broadband (> 20%) operation while keeping the drift length of the klystron short.
