Plasma physics

Diffusion process in which buildup of spatial charge creates electric fields which cause electrons and ions to leave the plasma at the same rate. Such electric fields are self-generated by the plasma ...

scintillation

Physics; Plasma physics

Generic term for rapid variations in apparent position, brightness, or color of a distant luminous object viewed through the atmosphere. A flash of light produced in a phosphor by an ionizing event. ...

shock waves

Physics; Plasma physics

Surfaces or sheets of discontinuity (i.e., abrupt changes in conditions) set up in a supersonic fields of flow, through which the fluids undergo a finite decrease in velocity accompanied by a marked ...

magnetohydrodynamics (MHD)

Physics; Plasma physics

The study of the interaction that exists between a magnetic field and an electrically conducting fluid. Used for geometrical hydromagnetics, hydromagnetics, hydromagnetism, and magnetogasdynamics.

phase velocity

Physics; Plasma physics

Of a traveling plane wave at a single frequency, the velocity of an equiphase surface along the wave normal.

cyclotron radiation

Physics; Plasma physics

The electromagnetic radiation emitted by charged particles as they orbit in a magnetic field. The radiation arises from the centripetal acceleration of the particle as it moves in a circular orbit.
