Nuclear fusion is a process where atomic nuclei combine to form a heavier nucleus, releasing a tremendous amount of energy in the process. This is the same process that powers stars, including our own Sun. Scientists have been trying to harness the power of nuclear fusion to create a new, clean source of energy for decades.
A promising way to achieving nuclear fusion on Earth is through the use of a device called a tokamak (eg. KSTAR in Korea). A tokamak is a device that uses a magnetic field to confine a plasma in the shape of a torus (a donut shape). The tokamak is designed to heat the plasma to extremely high temperatures and densities, allowing the atomic nuclei to fuse together.
Recently, with the advancements in AI and GPU computing technologies, new methods for simulating tokamak plasma in different ways are being developed. Our lab uses AI and simulation to virtually experiment with plasma and research tokamak optimization for effective nuclear fusion.
