Plasma physics

The electrical polarization of a horizontal conducting sheet of limited extent, when that sheet moves laterally through a magnetic field having a component vertical to the sheet. The Hall effect is ...

auroral zone

Physics; Plasma physics

Roughly circular bands around either geomagnetic pole above which there is a maximum of auroral activity. The zones lie about 10deg. to 15 deg. of geomagnetic latitude from the geomagnetic poles.

landau damping

Physics; Plasma physics

The damping of a space charge wave by electrons which move at the phase velocity of the wave and gain energy transferred from the wave.

arecibo

Physics; Plasma physics

Large radiotelescope facility located in Arecibo, Puerto Rico.

Hannes Alfven

Physics; Plasma physics

Pioneering Swedish plasma physicist, and winner of the Nobel Prize in Physics; now deceased.

global positioning system

Physics; Plasma physics

A satellite navigation system which will display many (up to 24) satellites in three sets of orbits by means of a precise time standard and three-dimensional information on position and velocity.

sudden ionospheric disturbances (SID)

Physics; Plasma physics

Complex combinations of sudden changes in the conditions of the ionosphere and the effects of these changes. This is used for geomagnetic crotchets andionospheric disturbances (SID).
