We extend Gluckstern results for the electric and magnetic polarizabilities of pumping holes in the wall of a circular liner surrounded by a co-axial circular shield to arbitrary non-circular geometries. The result is used for evalu-ating the pertinent beam coupling impedances in terms of a general perturbative formula using equivalent impedance boundary conditions at the liner’s wall.

Abstract
We extend Gluckstern results for the electric and magnetic polarizabilities of pumping holes in the wall of a circular liner surrounded by a co-axial circular shield to arbitrary non-circular geometries. The result is used for evalu-ating the pertinent beam coupling impedances in terms of a general perturbative formula using equivalent impedance boundary conditions at the liner’s wall.File in questo prodotto:
