The bandwidth of a klystron output cavity scales (approximately) as {rho}{sup 0.8}P{sup 0.2}, where {rho} is the beam perveance and P is the beam power. For high-perveance ({rho} > 10 {micro}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-modulated electron beam with a frequency-dependent 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 percent) operation while keeping the drift length of the klystron short.
