The R&D topics of the Institute of Technical Physics (ITEP) at the Karlsruhe Institute of Technology (KIT) cover all applications of superconductivity in the whole span from the fundamental research on the materials (technical and new superconductors) to superconducting devices (prototype and demonstrator). The research includes cryogenic structure materials and characterization of their low temperature properties, in particular advanced new materials. A leading research group is specialized on numerical modeling of superconductors and devices, creating new codes (addressing WP4.1.1).

Research topics are high field magnets for NMR and Fusion, Fault Current Limiters (FCL), transformers, high capacity cables for AC and DC power transmission, rotating machinery like wind energy generators, and superconductivity in future airplanes and space. Such applications ask for new cryogenic materials (addressing WP4.1.3). In particular High Temperature Superconductor Cables are developed and implemented with partners in new accelerator magnets and industrial power bars. It is the policy and part of the activities to contribute to standardization work (IEA TC90, VAMAS) and database acquisition for open access. Most of the R&D activities are performed in cooperation with other European institutions and commonly published in journals, proceedings, books. (addressing WP 4.1.4).

Cooperation partners include CERN, CEA, EPFL, Babcock-Noell, Bruker, Siemens ABB, Vision-S, Univ.Twente, IEE Bratislava, IFW Dresden, Airbus, TU Munich, BASF, THEVA, SuperOx
