Summary on Grant Application Form |
|
As the academic partner in a LINK programme on the enhancement of superconducting materials for fault current limiter applications, Cambridge University will support the industrial partners by carrying out focused basic research and materials engineering on the high temperature superconducting materials Bi2Sr2CaCu2O8 + s and YBa2Cu3O7- x . The former material has adequate properties for a first prototype to test engineering design principles and the main effort will be on scaling-up the processing, improving mechanical properties and the general uniformity and reproductibility of large section conductors. There will also be work on tailoring the variation of critical current with field and on the kinetics of the superconducting to normal transition. Since this material has limited economic potential for a full scale demonstrator, work will be carried out in parallel on the latter material which can exhibit high critical currents in large applied magnetic fields. This research will include control and enhancement of the critical currents of grain boundaries, the investigation of ion-mobility and diffusion during processing (particularly oxygen ions). Further aspects of the work will be the study of joining, cladding and support of conductors and investigation of issues of cycleability, lifetime prediction and failure modes.
