Applied Superconductivity Lab

The Applied Superconductivity Laboratory provides a variety of characterization methods to evaluate and test superconducting materials and devices. Whereas the main emphasis is on the development of superconducting magnetic bearings (SMB) for different applications, also other superconducting device components might be characterized. The methods include static and dynamic measurements of bearing properties like levitation forces, stiffness, damping or hysteretic losses. Additionally, bearing components such as permanent magnets, coils, superconducting bulks, tape stacks or single superconducting tapes can also be characterized.
