Phys. Rev. ST Accel. Beams 8, 124403 (2005) [8 pages]Transverse impedance of a smooth flat taper
Stupakov has used a perturbation method to estimate the transverse impedance at zero frequency of a rectangular collimator having characteristic taper length ℓ, half-width w, and average vertical half-aperture b0, under the condition b0≪w≪ℓ. We use the boundary perturbation method to approximate the transverse impedance of a flat, slowly tapered chamber in the complementary limit, w=∞.
