Numerical Investigation of Multi-Cavity Superconducting Radio-Frequency Resonators — •Johann Heller, Thomas Flisgen, Tomasz Galek, and Ursula van Rienen — Institut für Allgemeine Elektrotechnik, Rostock, Deutschland

For the thorough design of particle accelerators, the electromagnetic behavior of the accelerating resonators has to be investigated. These fields are computed numerically by solving the curl-curl equation, derived from Maxwells equations. The field patterns in large and complex structures can not be computed on standard workstation computers in reasonable time due to the huge number of degrees of freedom which arises from the discretization of the problem. For such type of problems, sophisticated parallel codes are employed on high-performance computers (HPC). Being very expensive, HPC platforms are rather rare so that it is difficult to access these computing infrastructures. Therefore, we recently proposed a concatenation scheme, denoted as State-Space Concatenations (SSC), which is able to compute complex RF structures on standard workstations. In this contribution large-scale multi-cavity applications of SSC are being compared to measurements related to FLASH.
