Both high critical current densities and low hysteresis-losses are needed for Nb3Sn strands used for poloidal coils in a nuclear fusion experimental reactor. Since our internal-tin route Nb3Sn wires have many advantages except for hysteresis-loss, it

Both high critical current densities and low hysteresis-losses are needed for Nb3Sn strands used for poloidal coils in a nuclear fusion experimental reactor. It is important for our internaltin route Nb3Sn wires to improve the loss immediately. Recen

Field operation and cooling test of high Tc coil made of Bi-based pancake coil were carried out. By the measurement of critical current distribution inside the high Tc coil, we found that the critical current of the edge pancake coil is lower than th
