The tuning system of broadband klystron amplifier

The modern computer technology does not work out the problem of broadband klystron amplifier design by itself. It needs for a good initial approach on the base of physical notions. To form a system of buncher cavity resonant frequencies and Q's, the problem of RF currents interaction in the drift spaces is especially important. This subject is considered in this paper and the remedies are determined for obtaining of a flat gain frequency response. At first the "skirtron" tuning system is used, then the second cavity is detuned down and a multiple-coupled network is formed near the first cavity. Some other possibilities are discussed.
