Title :
High-frequency impedance of small-angle collimators
Author_Institution :
Stanford Linear Accelerator Center, Stanford Univ., CA, USA
Abstract :
We give a review of possible parameter regimes for impedance of both round and rectangular tapered collimators based on the physical mechanism involved in formation of the beam wake field. A simple analytical method is presented for impedance calculation in the diffraction regime. Theoretical results are compared with recent measurements of collimator wake at SLAC
