This book serves as an introduction to plasma physics, starting from the basics and presenting it as a field that can be understood through physical intuition and qualitative reasoning, much like other branches of physics. The authors, a team of experts, aim to bridge the gap between theory, research, and practical applications. They explore advanced topics, such as the application of plasma physics to thermonuclear fusion and plasma astrophysics. The book covers a wide range of energy-related issues, including fusion power production, power balance, and the design of fusion reactors. It delves into fundamental plasma physics problems that are crucial for the development of fusion power, such as macroscopic equilibrium and stability, transport phenomena, and heating mechanisms. By combining theory, research, and practical applications, the authors provide a comprehensive resource for graduate students and researchers in the field of applied physics and nuclear engineering.
