The Large Helical Device (LHD) project involves construction of the world’s largest superconducting helical device, which employs a heliotron magnetic field originally developed in Japan. The objectives are to conduct fusion-plasma confinement research in a steady-state machine and to elucidate important research issues in physics and engineering for helical plasma reactors. The LHD comprisesa Plasma confinement device that employs superconducting coils, plasma heating systems and devices to measure and record plasma propeties and phenomena.
