Lecture
This lecture explores the confinement of plasma using open and closed magnetic field line configurations, focusing on the principles of magnetic mirrors and toroidal fields. It delves into the dynamics of particles in magnetic mirror fields, emphasizing the importance of perpendicular and parallel velocities. The challenges of confining plasma solely with a toroidal magnetic field are discussed, highlighting the need for additional confinement mechanisms. The lecture concludes by summarizing the key concepts of plasma confinement provided by different magnetic field line configurations.
