Accelerator technology II: waveguides and cavities

This chapter surveys aspects of electromagnetic fields inside of regions bounded by conductors, in scenarios of relevance to accelerator technology. It explains that the discussion was based on general considerations of electromagnetic wave propagation in vacuum, dielectrics, and conductors. It then builds the discussion of resonant cavity modes upon relevant concepts in waveguide theory. It clarifies the forms of fields in couple cavity linacs, devices that are also profitably viewed as TM waveguides in their own right. It uses the view of rf cavities as generalized oscillators to introduce...

This chapter surveys aspects of electromagnetic fields inside of regions bounded by conductors, in scenarios of relevance to accelerator technology. It explains that the discussion was based on general considerations of electromagnetic wave propagation in vacuum, dielectrics, and conductors. It then builds the discussion of resonant cavity modes upon relevant concepts in waveguide theory. It clarifies the forms of fields in couple cavity linacs, devices that are also profitably viewed as TM waveguides in their own right. It uses the view of rf cavities as generalized oscillators to introduce the Slater perturbation theorem, a powerful tool for tuning and measuring cavity characteristics.
