Plasma, consisting of electrons and ions, is electrically neutral ionized gas. Plasma plays an important role in modern engineering. In this course, students will learn from the basics of plasma physics, plasma generation, measurement, to industrial applications of plasma. The topics include excitation and ionization, motion of charged particles in electromagnetic fields, plasma as a group of particles, plasma as a fluid, collision and transport phenomena, confinement of plasma, waves in plasma, plasma diagnostics.
The aim of this course is to understand the physics and engineering, issues, and application of plasma science.
The concept and discussion of plasma physics have become one of the fundamentals in all aspects of science and engineering. Students will be able to understand applications of plasmas from viewpoints of engineering, starting with fundamental concepts such as movement of charged particles in electromagnetic field, characteristics as a group of charged particles, and ionization phenomena.
Plasma, discharge, ionization, excitation, Boltzmann equation, drift motion, magnetic moment, dispersion relation, sheath, thermonuclear fusion
