Superconductively levitated transport system - the SupraTrans project — •O. de Haas, L. Schultz, C. Beyer, P. Verges und G. Fuchs — Leibniz-Instistut für Festkörper und Werkstoffforschung Dresden, Helmholtzstr. 20, 01069 Dresden

The development and creation of a full working prototype of a superconductively levitated train is the aim of the SupraTrans project. It is a joint venture between research institutes (IFW Dresden), universities (Dresden University of Technology, University of Applied Sciences Dresden), industrial companies (ELBAS GmbH-railway consulting and engineering, Baumüller Kamenz-linear drives, CIDEON Bautzen-technical engineering) and the Dresden Transportation Company (DVB). In our contribution we will give a detailed insight into technology and physics of the levitation system and surrounding parts.

The SupraTrans technology uses the flux pinning in melt textured massive YBCO to stabilize the lateral and the vertical position of the vehicle on top of the magnetic track. This self-stabilization is the main advantage of the superconductive levitation in comparison to the already used Transrapid-technology, which needs an electronic control system to keep a constant distance between the train and the track. In a first step, permanent magnets will be used for the prototype rail. In further steps the permanent magnets will be replaced by electromagnets that provide the magnetic field for levitation and guidance.
