plasmapausen.

Brit.

/ˈplazməpɔːz/, U.S.

/ˈplæzməˌpɔz/,

/ˈplæzməˌpɑz/

Origin: Formed within English, by compounding. Etymons: plasma n., pause n.

Etymology: < plasma n. + pause n.

Physics.

The outer limit of a plasmasphere, marked by a sudden change in the plasma density and lying wholly within the magnetosphere (in the case of the earth extending up to several earth radii from its centre at equatorial latitudes).

1966 D. L. Carpenter in Jrnl. Geophysical Res. 71 695/1 With regard to nomenclature, the word ‘plasmapause’ will be used when the three-dimensionality of the knee phenomenon is emphasized... The word ‘plasmasphere’ will be used to indicate the dense region inside the plasmapause, and ‘plasma trough’ to indicate the tenuous region outside.

1971 New Scientist 1 July 8/2 The time at which Io crosses the plasmapause [of Jupiter] and sets off a burst of radio emission therefore depends on the Sun's activity.

1976 T. Beer Aerospace Environment vii. 137 We can expect a plasmapause on Mars somewhere above 400 km.

1993 New Scientist 24 July 16/3 Some of the instruments' most intriguing observations have been of the plasmapause—the upper boundary of the plasmasphere, which is also the inner portion of the magnetosphere.
