Plasma is matter that is so hot that the electrons are separated from atoms. The electrons float freely and the atoms become ions. This creates an ionized gas—plasma—that makes up nearly all of the visible universe. Recent ...

Kinetic instabilities commonly arise from anisotropic (different properties in different directions) electron velocity distributions within ionospheric, cosmic and terrestrial plasmas. But only a handful of experiments have ...
The hot ionized gas called a plasma is confined in a bagel-shaped tokamak by a strong magnetic field, part of which is generated by a strong electric current flowing through the plasma. Periodically, a sawtooth instability ...
