Abstract :
For a slowly tapered vacuum chamber with confocal elliptical cross-section, results obtained with the ABCI and GdfidL electromagnetic simulators are compared with analytic estimates for the transverse impedance at zero frequency. In the limits of round and flat chambers, we discuss the conditions for validity of the analytic approximations of Yokoya and Stupakov.
