SupraTrans - a superconductively levitated transport system — •Christoph Beyer, Oliver de Haas, and Ludwig Schultz — IFW Dresden, PF 270116, D-01171 Dresden, Germany
Based on investigations on a toy sized model levitation train [1], a full working demonstrator for a superconductively levitated transport system has been developed. The levitation and guidance system is based on flux pinning in melt-textured bulk YBa2Cu3O7−x (YBCO) that stabilizes the vertical and lateral positions of the vehicle above the magnetic track. The track is made of Nd-Fe-B permanent magnets mounted within softmagnetic iron yokes acting as flux collectors. The actual vehicle contains 4 cryostats. Using 10 rectangular shaped bulk YBCO blocks with dimensions of 35×90×15 mm3 in each of them a maximum total load of nearly 800 kg at 77 K has been achieved. More details about the capability of the system will be given in the contribution. The concept also includes a fast electromagnetic turnout switch to establish a highly branched transportation network. An experimental setup has been created for the toy sized model train and will complete the SupraTrans demonstrator.
