Plasma Physics

5_Plasma_Pysics

Plasma is a quasi-neytral gas of charged and neutral particles, which basic properties are determined by collective interaction of charged particles.

For what it is necessary to study plasma?

– Because most of the observable matter in the universe is in the plasma state.
– Because the Sun, the solar wind, magnetosphere and ionosphere is a plasma formations.
– Because it has wide application: controlled thermonuclear fusion, MHD generators, plasma engines, gas discharge, etc.
– Because it is closely related branches of science such as astrophysics, solar physicsб solar-terrestrial relations, geophysics.
