Tokamak design
A tokamak is a device designed to achieve nuclear fusion by containing hot plasma—a superheated, ionized gas—using powerful magnetic fields. It looks like a doughnut-shaped chamber, where magnetic coils generate fields that keep the plasma stable and confined at extremely high temperatures. This prevents the plasma from touching the walls, allowing fusion reactions to occur safely inside. The goal is to mimic the sun’s energy process on Earth, producing clean and abundant energy. Tokamaks are a central approach in fusion research, aiming to develop a sustainable and safe energy source for the future.
