摘要
A two-dimensional finite element beam coupling impedance solver for arbitrary transverse geometries and material distribution is presented. The solver is based on open source software and is applicable to space charge and resistive wall longitudinal and transverse impedances. The frequency and the beam velocity can be chosen arbitrarily and also dispersively lossy materials are supported. Space charge impedance, a thin resistive beam pipe, a ferrite ring, and a carbon collimator are presented as application examples.
