Abstract
During synchrotron source development much attention is devoted to beam instability, which limits beam emittance and lifetime. One of the sources of beam instability is the electromagnetic field excitation in the vacuum chamber heterogeneous regions. The quantitative characteristic of the beam-chamber interaction is the coupling impedance. This paper describes modernization of the program BeamImpedance2D, which accelerates resistive impedance calculations by unitizing complex equation forms and distributed calculations among the computation cluster nodes. Comparison between calculations of the real vacuum chamber and its approximation are presented.
