Abstract :
Cold beam pipes like in SSC or LHC require shielding tubes with pumping holes called liner. As a first approximation instead of holes a tube with an arbitrary number of rotationally symmetric interruptions is analyzed using the mode-matching-technique. Results are presented for the longitudinal coupling impedance
