Resonantly Coupled Accelerating Structures for High-Current Proton Linacs

The results of model studies and an equivalent circuit analysis of the operation of a chain of cavities in the /g=P//2 mode is given. Various /g=p//2 mode structures are described and the performance of models of these structures is discussed. Results of numerical solutions to an equivalent circuit applicable to the problem are also given, which include frequency error tolerances and coupling tolerances, for typical cases of interest. Multiple drive of a long resonator chain is also discussed.
