Abstract (Englisch)

In the face of stiff competition from USA and Japan, this project will maintain Europe's depth of strength in the RTD of high temperature super-conducting materials, so that European Industry can take full advantage of the new market in HTS applications that will emerge ten years from now. Round and square Bi-2223 wires with high currents will be designed, manufactured and then transposed and stranded for a power-link and a coil. New-loss conductors will be developed with twisted filaments and reistive barriers over 200m lengths. New reaction mechanisms will be defined with new precursor powders that will significantly increase the current capacity of Bi-2223 conductors. This work will be supported with new 3D modelling and characterisation studies. These will aid the design of better geometries and quantify the conductor benefits.
