Basic Properties of High Temperature Plasmas

Abstract

As temperature is increased, the state of matter changes from solid to liquid, and 3 then to gas.With further increase in temperature, some or all of the atoms of neutral gas are ionized. A plasma is a partially or fully ionized gas where ionization and recombination are balanced to keep the ionized gas to be charge neutral as a whole. Once the charge neutrality is broken, a large electric field is locally created to drive the plasma unstable. In this sense, the charge neutrality (rigorously quasi-charge neutrality) is essentially important. This implies that the potential in the plasma is usually determined through not Poisson’s equation but equations of motion for the electrons and ions under the charge neutrality.KeywordsPhase VelocityDebye LengthCollective MotionVelocity Distribution FunctionLangmuir WaveThese keywords were added by machine and not by the authors.
