Spectral characteristics of plasma sheet ion and electron populations during undisturbed geomagnetic conditions
We have determined the spectral characteristics of central plasma sheet ions and electrons observed during 71 hours when geomagnetic activity was at moderate to high levels (AE ≥ 100 nT). ParticleExpand

A proposed production model of rapid subauroral ion drifts and their relationship to substorm evolution
Multisatellite data are used to examine the temporal relationship between Subauroral Ion Drifts (SAID) and the phases of an auroral substorm. Utilizing images of auroral luminosities taken by theExpand

Upstream hydromagnetic waves and their association with backstreaming ion populations: ISEE 1 and 2 observations
Measurements from the Lepedea plasma instruments and the flux gate magnetometers on ISEE 1 and 2 are used to examine the nature of the hydromagnetic waves associated with the various classes of ionsExpand

Energy spectra of plasma sheet ions and electrons from ∼50 eV/e to ∼1 MeV during plasma temperature transitions
Measurements of charged particles in the plasma sheet by the low energy proton and electron differential energy analyzer (LEPEDEA) and medium energy particle instrument (MEPI) on ISEE 1 are combinedExpand

The plasma sheet boundary layer
The plasma sheet boundary layer is a temporally variable transition region located between the magnetotail lobes and the central plasma sheet. We have made a survey of these regions by using particleExpand
