| Abstract | Wakefield generation by the collimation system is known to be a critical linear collider design issue. Optimization of the collimators represents a tradeoff between beam quality (halo reduction) and luminosity reduction. The primary objective is to reduce both short range (resonant) and long range (resistive) deflecting wakefields from collimators that reduce the luminosity of the machine. We consider the CLIC BDS (beam delivery system) and examine the potential for using dielectric rather than highly conducting materials for collimation. We present some examples of the flexibility gained by having control over the permittivity and conductivity of the collimator. We discuss simulation efforts with BBU-3000, Arrakis, and other proprietary and commercial codes. We have also proposed impedance measurements of low conductivity and dielectric collimator prototypes at the new FACET facility at SLAC, which provides unprecedented short drive bunches and the availability of a witness beam to probe the induced wakefields. |
