In this paper we present a model for the rf power distribution to multiple super-conductive cavities from a single klystron. The goal of this model is to find a distribution scheme in which the cavities are operated as close to their quench limit as possible. The approach presented in this work consists of setting all cavities to the same QL value by adjusting the power coupler, and optimizing the power (Pk) distribution individually to each cavity to maximize the vector sum voltage. The proposed approach yields an operating gradient very close to the theoretical limit and offers a great operational benefit as the gradient stability is conserved for any beam current.
