A new track for a superconductively levitated transport system — •Christoph Beyer, Zongyou Ren, Oliver de Haas, Peter Verges, Günter Fuchs, and Ludwig Schultz — Leibniz-Instistut für Festkörper und Werkstoffforschung Dresden, Helmholtzstr. 20, 01069 Dresden

Based on investigations on a toy sized model levitation train[1], we have constructed a new permanent magnetic track for a superconductively levitated transport system, which will be the base of the demonstrator in our SupraTrans project. First results exhibit similar levitation forces compared to existing systems [2] with a three times lower material outlay.

The track is made out of a combination of Nd-Fe-B permanent magnets and soft magnetic steel as flux collector. In the experimental setup we used a rectangular bulk melt-textured YBCO block with the dimension of 30 × 90 × 15 mm. We achieved a maximum levitation force of around 200 N at 77 K and a vertical stiffness of 10 N/mm in zero-field-cooled mode.
