1962 W. B. Thompson Introd. Plasma Physics viii. 235 Since the wavelength is so small, this instability is almost independent of the macroscopic geometry, and represents one of the ‘micro-instabilities’.

1971 Science Year 1972 222 Fusion researchers have been trying to find magnetic-bottle configurations that will be able to reduce the microinstabilities to acceptable proportions.

1992 S. P. Maran Astron. & Astrophysics Encycl. 551/1 Plasma instabilities are categorized as macroinstabilities (derivable from a fluid description) and microinstabilities (derivable only from a kinetic description).
