Plasma physics is the study of matter in the form of plasma, which is a state of matter similar to gas but consisting of charged particles. Plasma physics explores the behavior of plasma, its properties, interactions, and applications in a wide range of fields such as astrophysics, nuclear fusion, materials processing, and space science. Researchers in this field study phenomena like plasma waves, instabilities, magnetic confinement, and plasma heating in order to better understand and control the behavior of plasmas for practical uses. Plasma physics plays a crucial role in the development of technologies such as fusion energy, plasma processing, and space propulsion.
