Abstract
To protect a large-scale superconducting magnet from damage that may be caused by a quench, current capacity of the magnet conductor should be increased. However, increase in current capacity of the conductor produces serious problems of magnet technology. For example, a large scale superconductor is hard to wind, which is critical especially for a large scale magnet of complicated shape, and it is often liable to suffer from instability problems due to electromagnetic phenomena, because diffusion time of current and magnetic field across the conductor cross section is large1. It is very difficult to estimate performance of a large scale conductor from that of a small scale conductor of similar figure, therefore, development of the large scale conductor needs large amount of cost and time, because the full scale conductor should be tested.
