Title Wakefield Suppression in a Manifold Damped and Detuned Structure for a 380 GeV CLIC Staged Design
Abstract The first stage of the Compact Linear Collider (CLIC)project aims to collide electrons and positrons at a 380 GeVcenter of mass energy. In the baseline design the main linacsfor this staged approach are required to achieve a gradientof 72 MeV/m, with the surface electromagnetic fields (EM)and the transverse long-range wakefields bound by beamdynamics constraints. The baseline design utilizes heavydamping in a traveling wave (TW) structure. Here we re-port on an alternate design, which adopts moderate dampingalong with strong detuning of the individual cell frequen-cies. In the context of this Damped and Detuned Structure(DDS) design, we study Gaussian and hyperbolic secantdipole distributions, together with interleaving of successivestructures, to facilitate long-range transverse wakefield sup-pression. Both analytic and modal summation approaches, inthe quasi-coupled approximation, produce consistent results.In the optimisation scheme we opt for a dipole frequencybandwidth of 17.7% (2.92 GHz).
