phosphor
Physics; Plasma physics
A substance that can give off visible light after it has absorbed some form of radiation like x-rays.
E-region
Physics; Plasma physics
A daytime layer of the earth's ionosphere roughly between the altitudes of 85 and 140 km.
ionosphere
Physics; Plasma physics
The region of the earth's upper atmosphere containing a small percentage of free electrons and ions produced by photoioniza- tion of the constituents of the atmosphere by solar ...
ionization patch
Physics; Plasma physics
Solar-produced plasma that has been detached from the dayside subauroral ionosphere by a changing convection pattern and transported.
air glow
Physics; Plasma physics
Amorphous, optical radiation continuously emitted by a planetary atmosphere. It extends from the far ultraviolet into the near infrared. The Earth's air glow arises mainly from ...
cyclotron radius
Physics; Plasma physics
Radius of orbit of charged particle about a magnetic field line. Also called gyroradius, Larmor radius.
turbulent flow
