DOI:https://doi.org/10.2172/800015· OSTI ID:800015

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.
