side-coupled cavity accelerator

…structural variation, known as the side-coupled cavity accelerator, in which acceleration occurs in on-axis cells that are coupled together by cavities mounted to their sides. These coupling cavities serve to stabilize the performance of the accelerator against changes in the resonant frequencies of the accelerating cells.

… in New Mexico, is the side-coupled-cavity structure. In this design walls divide the long Alvarez tank into individual cavities that are linked by relatively short drift tubes. Smaller cavities along one side feed radio-frequency power to pairs of adjacent accelerating cavities in such a way that an alternating electric field…
