Nonlinear dynamics in the SSC (Superconducting Super Collider), Experiment E778
This paper concentrates on the accelerator physics processes which are expected to limit the performance of the SSC. There are two broad classes of accelerator physics processes --- single particle and collective. Collective effects are caused by the macroscopic electromagnetic fields generated by the numerous circulating charged particles (about 10{sup 10} particles per bunch). These fields are influenced by the environment, such as the metallic vacuum chamber walls, and act back upon the circulating charged particles. For example, a single bunch can disrupt itself significantly on one pass through a particular structure in an accelerator. Or, if the fields ring for long enough and have the right frequency, a single bunch can be affected on subsequent turns by the disturbance it laid down on a first turn. Multi-bunch effects occur when a trailing bunch reacts to the ringing fields laid down by preceding bunches. The performance of the SSC is considered here only in the context of single particle models, in which a test particle circulates a collider for many turns in the presence of static electromagnetic fields. These fields are conceptually divided into linear restoring forces --- in which the motion is stable --- and nonlinear perturbations.
