Abstract
In the field of side-cavity coupled accelerators the accelerating cavity to which the accelerating power input is connected has preferably a smaller diameter than the other accelerating cavities. A side cavity is connected by a separate passage to the accelerating cavities of different diameter it couples together, whereby the areas of the coupling irises formed where said passages enter said accelerating cavities can be independently controlled by selecting the length of the respective passage. This separate passage arrangement is particularly described in an accelerator which comprises a plurality of interlaced substructures, with each substructure having a plurality of accelerating cavities disposed along the particle beam path and having side cavities disposed away from the beam path for electromagnetically coupling the accelerating cavities. A standing radio-frequency electromagnetic wave is fed to an accelerating cavity in each substructure so there are plural driven cavities in a single accelerator. Thus, the separate coupling passage arrangement between the side cavity and the accelerating cavities it couples is particularly valuable in said multiple substructure arrangement.
