A one megawatt S-band gridded klystron for a wide band pulse compression radar
Abstract
A description is presented of the methods used to design the buncher section and the output circuit of the klystron in order to obtain the relatively very large bandwidth. Aspects of tube construction are discussed, taking into account the gridded gun, the beam configuration, the collector, the buncher, and the extended interaction output. Aspects of tube performance are examined. Using the overlapping mode extended interaction circuit for the output cavity of a klystron, it is possible to achieve very broad frequency coverage. At least 7% has been demonstrated at the 1.0 MW output power level, and efficiencies of up to about 50% are also obtained. It is also possible to achieve the corresponding bandwidths with sufficient gain from a conventional klystron buncher using at least up to seven driver cavities and employing existing design techniques to avoid dips or zeros within the required band.
