The Plasma Mantle as the Origin of the Plasma Sheet

1976
In a recent review, entitled ‘Origin of the Plasma Sheet’, Hill (1974) introduced the subject in the following way: “The plasma sheet is a region of hot plasma (~107K) that surrounds the Earth, filling the distant magnetosphere and separating the northern and southern lobes of the magnetospheric tail; its origin is one of the basic outstanding problems

On the thermodynamics of the plasma sheet

Journal of Geophysical Research: Space Physics, 1991
The evidence for nonadiabatic transport in the quiet central plasma sheet is reinvestigated. In this study, we include AMPTE IRM data from the plasma sheet boundary layer and active times selected on the basis of large AE values. We find that as the plasma is transported from the plasma sheet boundary layer into the central plasma sheet, both its ...

Comparative study of plasma wave activity in the plasma sheet boundary and near Earth plasma sheet

Advances in Space Research, 1986
Abstract The general structure of low frequency wave activity in the Earth's plasma sheet and its boundary layer is studied on the basis of the measurements made by ‘Prognoz-8’ satellite in the northern night and morning parts of the magnetotail. Pronounced wave activity is permanently observed in the high latitude parts of the plasma sheet boundary ...

Runaway electrons in plasma current sheets

Physical Review Letters, 1994
It is shown that a runaway electron population accelerates along the main magnetic field in a Sweet-Parker current sheet. After a characteristic distance the entire current is carried by runaways. The thickness of this runaway sheet is much smaller than the original Ohmic sheet. The influence of microinstabilities is discussed.

Origin of the plasma sheet

Reviews of Geophysics, 1974
The plasma sheet is a region of hot plasma (∼107 °K) that surrounds the earth, filling the distant magnetosphere and separating the northern and southern lobes of the magnetospheric tail; its origin is one of the basic outstanding problems of magnetospheric physics.

Adiabatic plasma convection in the tail plasma sheet

Planetary and Space Science, 1978
We investigate the transport process of electrons in the tail plasma sheet by convection electric fields, under the assumption of conservation of the first two adiabatic invariants. The variation of the electron distribution function, and hence the bulk parameters with distance from the Earth are calculated.

ISEE observations of the plasma sheet boundary, plasma sheet, and neutral sheet: 1. Electric field, magnetic field, plasma, and ion composition

Journal of Geophysical Research: Space Physics, 1986
The first simultaneous study of dc and ac electric and magnetic fields, E × B velocity, plasma flows, β, total energy density, energetic particles, and ion composition from the ISEE satellites and ground and interplanetary magnetic fields has been made to determine (1) the relationship of the previously observed electric fields at the plasma sheet ...

Observations of Double Layers in Earth’s Plasma Sheet

Physical Review Letters, 2009
We report the first direct observations of parallel electric fields (E_{ parallel}) carried by double layers (DLs) in the plasma sheet of Earth's magnetosphere. The DL observations, made by the THEMIS spacecraft, have E_{ parallel} signals that are analogous to those reported in the auroral region.

Birkeland currents in the plasma sheet

Journal of Geophysical Research: Space Physics, 1993
A search was conducted for the signatures of Birkeland currents in the Earth's magnetic tail, using observed values of Bx and By from large sets of spacecraft data. The data were binned by x and y for −10 > xGSM > −35 and |yGSM| ≤ 20RE (≤ 30 RE for xGSM ≤ −25 RE) and in each bin their distribution in the (Bx, By) plane was fitted by least squares

Drift Waves in Sheet Plasmas

Journal of the Physical Society of Japan, 1983
Electrostatic drift waves driven by a Gaussian density profile in a sheet plasma of thickness of the order of the ion Larmor radius ρ i have been studied numerically. The frequency range considered is less than the ion cyclotron frequency ω c i . The method is based on an integral equation in wavenumber space derived from the Vlasov-Poisson system of ...
