KIT Superconducting Undulator and Magnet Developments - Overview and State of the Art R&D on HTS Technology

Undulators are widely used in synchrotron storage rings and free-electron laser facilities. With the advent of low- temperature superconductors (LTS), a new generation of superconducting undulators (SCUs) emerged, including the recent new THz LTS undulator for FLUTE. At KIT, state- of-the-art magnetic and cryogenic measurement capabilities — provided by the Magnet and Cryogenics Facilities (MCF) and the Accelerator Technology Platform (ATP) — form a foundation for the development and characterization of these systems. Building on this experience, KIT is now advancing mag- nets and undulators based on high-temperature supercon- ductors (HTS), aiming for compact, sustainable, energy- and resource-efficient solutions. These activities are driven by in-house research and providing the full value chain of HTS technology from tape development via structuring to prototypes and tests in real-world environments at KIT. In this contribution, we provide an overview of our current developments and the supporting experimental infrastruc- ture.
