About 99% of the visible universe is formed of plasma. Applications include electric lamps, lasers, medical devices, energy converters, water purifiers and flat-panel video displays (see plasma display). The behavior and properties of plasmas have aroused interest and creative work among scientists and engineers. Our research is broadly based on free electron physics, accelerator science, plasma physics and atomic and molecular spectroscopy. The resulting super-ionized gas is a plasma, which can conduct a large and sustained electric current. It is a basic research discipline that has many different areas of application space and astrophysics, controlled fusion, accelerator physics and beam storage.

Plasma physics is the study of charged particles and fluids interacting with self-consistent electric and magnetic fields. Contributions to Plasma Physics invites you to contribute to special issues on selected topics. An ionized gas, unlike a gas in its normal condition, can conduct electrical current to a limited extent. When a gas is subjected to heat or an electric field, some of its atoms become ions, and the gas is said to be ionized. In a plasma, a significant number of electrons have such high energy levels that no nucleus can hold them.Īn atom that has lost some of its electrons, thereby attaining an electric charge, is an ion. In laboratory plasmas, instabilities tend to promote transport, undermining magnetic confinement strategies and forestalling the development of practical fusion reactors. Some electrons can move from atom to atom if an electrical current flows in a solid or liquid, but the motion occurs as short jumps by individual electrons between adjacent nuclei. Plasma physics has been preoccupied with the study of instability since the first experiments in controlled thermonuclear fusion in the 1950s (Bishop, 1958 ). Normally, the electrons in a solid, liquid, or gaseous sample of matter stay with the same atomic nucleus. The school focuses on plasma physics and its manifestations in laboratory experiments, space environment and in astrophysics. Plasma has been called the fourth state of matter, the other three being solid, liquid and gas. Space Plasma Physics examines near-Earth and planetary plasmas and solar plasma phenomena through a combination of computational and theoretical tools as. Plasma is a form of matter in which many of the electrons wander around freely among the nuclei of the atoms.
