Abstract

The impedance and the longitudinal wake field in a superconducting beam pipe are derived. At low frequencies, this impedance is purely inductive, while at higher frequencies it approaches the resistive-wall impedance of a normal conductor. For very short bunches, the resistive heating of the beam pipe can induce quenches of the superconductor.
