Tokamak Concept: Main Elements and Properties

This lecture covers the main elements and properties of a tokamak, including the magnetic field, plasma current, shaping, safety factor, equilibrium, and the largest tokamak in operation, JET. It explains the geometry, plasma shaping techniques, MHD equilibrium, Grad-Shafranov equation, safety factor, and typical profiles in a tokamak. The presentation also includes a brief history of tokamaks, focusing on the JET tokamak's design, operational parameters, and fusion technology. The spherical tokamak concept is introduced, highlighting its differences from conventional tokamaks. The lecture concludes with a summary of key points and mentions the upcoming lecture on stellarators.
