Equivalent circuit modelling as a design tool for particle accelerator RF components

This paper presents a comprehensive approach to generating and utilizing accurate equivalent circuits for structures commonly found in the particle accelerator domain. After a discussion of equivalent circuits in general, a systematic process for determining the appropriate circuit topology is outlined, and a method for finding circuit element values is introduced. The proposed methodology is demonstrated in detail, supported by four illustrative examples. Equivalent circuit element values are provided. An example of a decomposition strategy for handling complex structures is given. Additionally, a list of typical applications of equivalent circuits is provided with brief descriptions.
