TLDR
In this paper, the characteristics of the high-latitude boundary region of the plasma sheet have been analyzed using particle and field data obtained by eight ISEE spacecraft experiments, and the results show that the region supports intense ion flows, large amplitude electric fields, and enhanced broad-band electrostatic noise.Abstract:
Particle and field data obtained by eight ISEE spacecraft experiments are used to define more precisely the characteristics of the high-latitude boundary region of the plasma sheet. A region immediately adjacent to the high-latitude plasma sheet boundary has particle and field characteristics distinctly different from those observed in the lobe and deeper in the central plasma sheet. Electrons over a broad energy interval are 'field-aligned' and bidirectional, whereas in the plasma sheet the distributions are more isotropic. The region supports intense ion flows, large-amplitude electric fields, and enhanced broad-band electrostatic noise.read more

Electrostatic solitary waves (ESW) in the magnetotail: BEN wave forms observed by GEOTAIL
Hiroshi Matsumoto,Hirotsugu Kojima,T. Miyatake,Yoshiharu Omura,Masaki Okada,Isamu Nagano,Minoru Tsutsui +6 more
TL;DR: In this article, a nonlinear BGK potential model is proposed as the generation mechanism for the electrostatic solitary wave (ESW) based upon a simple particle simulation which considers the highly nonlinear evolution of the electron beam instability.

Auroral arc thicknesses as predicted by various theories
TL;DR: In this article, the authors examined 12 electron acceleration mechanisms and 10 generator mechanisms for auroral arcs, and a characteristic auroral-arc thickness was worked out for each mechanism except one, and the arc thicknesses were then mapped down to the ionosphere along the terrestrial magnetic field lines; near the Earth, a dipole magnetic field model was used, and farther from the Earth the mapping included the effects of magnetic field-line draping.

Whisper, a resonance sounder and wave analyser: Performances and perspectives for the Cluster mission
Pierrette Décréau,P. Fergeau,V. Krannosels'kikh,M. Lévêque,Ph. Martin,Orélien Randriamboarison,F. X. Sené,Jean-Gabriel Trotignon,P. Canu,P. B. Mögensen +9 more
TL;DR: The WHISPER sounder on the Cluster spacecraft is primarily designed to provide an absolute measurement of the total plasma density within the range 0.2-80 cm-3 as discussed by the authors. But this is achieved by means of a resonance sounding technique which has already proved successful in the regions to be explored.
