At the KIT storage ring KARA (KArlsruhe Research Accelerator) it is
planned to install an impedance manipulation structure in a versatile chamber
to study and eventually control the in
uence of an additional impedance on
the beam dynamics and the emitted coherent synchrotron radiation. For this
purpose the impedance of a corrugated pipe is under investigation. In this contribution,
we present results of simulations showing the impact of different
structure parameters on its impedance.
