Fusion research is the study of nuclear fusion, a process where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy. This process powers the sun and has the potential to provide a nearly limitless and clean energy source on Earth. Scientists aim to replicate this process in controlled environments, using advanced technologies and materials. One of the main challenges in fusion research is achieving the necessary conditions for fusion to occur, including extremely high temperatures and pressures. Facilities like the International Thermonuclear Experimental Reactor (ITER) are being developed to explore these conditions and advance our understanding of fusion energy.
