This paper reports on forced-cooled superconducting coil studied for Large Helical Device (LHD), which will be a main experimental apparatus of National Institute for Fusion Science (NIFS). To achieve main requirements for LHD, a large current, high current density NbTi cable-in-conduit type conductor of 10 kA, 47 A/mm{sup 2} at 8 T was developed. The test coil was wound in a one layer solenoid, and tested at an operating current of 10 kA in a superposed field of about 7 T, at the hydraulic condition of 1.0 MPa, 4.5 K and 10 g/s supercritical helium.
