| Abstract | YBCO Coated Conductor (CC) are very attractive for very high magnetic field coil with lower cryogenics need. We study two major aspects of HTS coil building. First the results of critical current measurements on YBCO tape provided by SuperPower are presented for a large temperature range and in parallel magnetic field configuration. A model is also proposed to extrapolate those measurements at other temperatures and fields. Then we focus on the critical aspect of junctions between pancakes. Junctions in cylindrical configuration are studied using three different soldering materials. The results are promising for further coil building. |
