LHD (Large Helical Device)

The Large Helical Device (LHD) is a nuclear fusion experiment located in Japan, designed to explore the potential of fusion as a clean energy source. It uses a unique helical (spiral) shape to confine hot plasma—a superheated gas where fusion occurs—using powerful magnetic fields. By mimicking the processes that power the sun, LHD aims to understand how to sustain fusion reactions efficiently. The insights gained from LHD are crucial for developing practical fusion energy systems, which could provide a sustainable alternative to fossil fuels in the future.
