Abstract：
Electric field distribution of a coupled cavity chain is used to calculate RF Parameters of individual cell in the chain. When the characteristic frequencies of a coupled cavity chain and the electric field distribution of each mode are known, by equivalent circuit model, one can solve the RF parameters of each individual cell and the coupling factors between them. This method is useful in designing and tuning a cavity chain of a linear accelerator, especially a non-periodic long structure. A description of the mathematical model and calculating experience are presented.
