Abstract :
On-site winding of two helical coils of LHD started at the beginning of 1995, using a numerically controlled winding machine. They are large-scale pool-cooled superconducting coils which are designed to satisfy fully stabilized criterion. The conductor consists of Nb-Ti/Cu strands with a pure aluminum stabilizer and copper sheath. The main demanded values for winding the coils are 2.0 mm and 65 μm for the accuracy of coil and the average gap between layers, respectively. A winding method was established by trial of winding
