This paper reports on the development of Nb{sub 3}Sn superconductors for AC use and fabricated a coil. The Nb{sub 3}Sn superconductors were manufactured using the internal tin diffusion process. To reduce AC losses the spacing between Nb filaments was designed to be 0.5 {mu}m, consequently, the space factor of Nb filaments was 6%. The diameter of a strand is 0.2 mm, and the diameter of a Nb filament is 0.4 {mu}m. AC losses in the strand were 180(kW/m{sup 3}) at 0.5 Tesla (60 Hz, peak value). A coil was made using the Wind and React method using conductors composed of 7 {times} 7 strands. Specifications of the coil are included.
