摘要：
Superconducting helical coils of the Large Helical Device (LHD) requires the superconducting conductors with large current capacity from 20kA to 30kA and high current density of 55A/mm2 at 8T. NbTi superconductor with pool boiling is selected considering the large electromagnetic force and the complicated helical windings. Several conductors are designed aiming to study how the difference of the position of pure aluminum in the conductors affects the stability and the mechanical properties. Scale-down R&D conductors with the operational current from 7kA to 10kA were made on an experimental basis. We have been testing these scale-down conductors about the superconducting characteristics, the stability and the mechanical properties. The detail of design and test results about the superconducting characteristics are described.
