Plasma Physics and Fusion Energy

This lecture covers the fundamental concepts of plasma physics, nuclear fusion, and the experimental techniques used to study tokamak boundary plasmas. Starting with the definition of plasma as the fourth state of matter, the instructor explains the energy generation process in stars through nuclear fusion. The goal of fusion research is to harness this energy source on Earth for clean and sustainable electricity production. The lecture delves into the high energies required for fusion reactions, the fuel sources like deuterium and lithium, and the main elements of a future fusion reactor. It also discusses the challenges of confining high-energy particles and the attractive features of fusion as a safe, clean, and abundant energy source.
