REBCO coated conductors have several characteristics which are superior to other superconductors. For example, its critical current is quite high even in the presence of high magnetic fields. Therefore, REBCO coated conductors make it possible to raise the operational temperature of superconductor applications. In turn, higher operational temperatures mean that the magnet cooling system consumes less energy. In the case of Maglev applications, it also means downsizing of the on-board power source and a reduction in the overall weight. A trial REBCO magnet that capable of generating 5 T (Tesla) was built. The magnets demonstrated that a magnetic flux density of 5 T was achievable at 45 K.
