The Nihongo|Large Helical Device |大型ヘリカル装置|Ōgata Herikaru Sōchi is a fusion research device in Toki, Gifu, Japan and is the largest superconducting stellarator in the world and employs a heliotron magnetic field originally developed in Japan. The objective of the project is to conduct fusion plasma confinement research in a steady-state in order to elucidate possible solutions to physics and engineering problems in helical plasma reactors. The LHD uses neutral beam injection, ion cyclotron radio frequency (ICRF), and electron cyclotron resonance heating (ECRH) to heat the plasma, much like conventional tokamaks.
