Investigation of an alternate means of wakefield suppression in the main linacs of CLIC
Abstract
We report on suppression of long-range wakefields in CLIC accelerating structures. Strong detuning and moderate damping is employed. In these initial design studies we focus on the CLICG structure and enforce a moderate Q of 300 and 500. We maintain a dipole bandwidth of approximately 1 GHz as specified from breakdown constraints in a modified structure, CLICDDS. The circuit model, which facilitates a rapid design of manifolds slot-coupled to the main accelerating cells, is described.
