K-STAR (Korean Superconducting Tokamak for Advancing Research)

K-STAR, or Korean Superconducting Tokamak for Advancing Research, is a fusion research facility in South Korea designed to explore nuclear fusion as a potential source of clean energy. A tokamak is a device that uses powerful magnetic fields to confine hot plasma—an ionized gas where fusion occurs—at extremely high temperatures. K-STAR aims to study and improve fusion technology, contributing to global efforts to harness fusion energy, which could provide a sustainable and abundant energy source, similar to the processes that power the sun.
