Another point will be the integration of nano-engineered superconducting materials into power application systems. Due to the financial dimension for realizing industrial power application systems, already existing demonstration systems (motors, magnets) or systems which are currently set-up in the frame of other projects will be used to test the applicability of the wires and bulk material that will be prepared and analysed by NESPA.
The winding of HTS superconducting magnets is a delicate task that severely depends on the peculiar mechanical properties of superconducting wires and tapes. Not only the handling of the superconducting material itself, but its compatibility with the other components of the magnet should be studied. The electrical insulation of the superconductor also needs to be investigated. The optimization of such processes will be carried out in order to demonstrate the feasibility of superconducting magnets based on MgB2 and coated conductors. Their properties will be studied both by cooling the winding in a cryogenic liquid as well as in a cryogenic-free environment, which is more suitable for a number of potentially useful industrial application (ASG).
In the framework of this Key task also low ac-loss and/or high Jc coated conductors, nano-engineered MgB2 PIT conductors and improved bulk materials will be used in motor demonstrators that are currently under development at Siemens.
