Plasma Physics

Different types of plasmas plasmas in terms of typical densities and temperatures.
International Thermonuclear Reactor (ITER) is under construction in France to demonstrate fusion power in hot plasma.

Plasma is the fourth state of matter, consisting of electrically charge remnants of atoms in the form of electrons and ions. Plasma is found almost everywhere on Earth and in space - only the invisible dark matter is more abundant. For example: the vast regions between galaxies in galaxy clusters are filled with hot magnetized plasmas; stars are dense plasmas heated by fusion reactions; computer processors are fabricated using cold chemically reacting plasmas; and powerful lasers can make relativistic plasmas in laboratories. None of these plasmas are quiescent; they wriggle and shake with instabilities and turbulence, and sometimes they erupt with spectacular forces as exemplified by  solar flares in Sun's outer atmosphere (corona).
