The electric-field and wave experiment (EFW) on Cluster is designed to measure the electric field and density fluctuations with sampling rates up to 36000 samples s-1 as mentioned in this paper, which can also be used to determine the electron density and temperature.Abstract:
The electric-field and wave experiment (EFW) on Cluster is designed to measure the electric-field and density fluctuations with sampling rates up to 36000 samples s-1. Langmuir probe sweeps can also be made to determine the electron density and temperature. The instrument has several important capabilities. These include (1) measurements of quasi-static electric fields of amplitudes up to 700 mV m-1 with high amplitude and time resolution, (2) measurements over short periods of time of up to five simualtaneous waveforms (two electric signals and three magnetic signals from the seach coil magnetometer sensors) of a bandwidth of 4 kHz with high time resolution, (3) measurements of density fluctuations in four points with high time resolution. Among the more interesting scientific objectives of the experiment are studies of nonlinear wave phenomena that result in acceleration of plasma as well as large- and small-scale interferometric measurements. By using four spacecraft for large-scale differential measurements and several Langmuir probes on one spacecraft for small-scale interferometry, it will be possible to study motion and shape of plasma structures on a wide range of spatial and temporal scales. This paper describes the primary scientific objectives of the EFW experiment and the technical capabilities of the instrument.read more

Cluster - Science and Mission Overview
TL;DR: The European Space Agency's Cluster program as discussed by the authors is designed to study the small-scale spatial and temporal characteristics of the magnetospheric and near-Earth solar wind plasma, which is composed of four identical spacecraft which will be able to make physical measurements in 3D. The relative distance between the four spacecraft will be varied between 200 and 18000 km during the course of the mission.

TL;DR: In this paper, the authors present studies of the electric field data from various regions along the CLUS-TER orbit. They all point towards a very high coherence for phenomena recorded on four spacecraft that are sepa- rated by a few hundred kilometers for structures over the whole range of apparent frequencies from 1 mHz to 9 kHz.

Self‐consistent theory of time‐dependent convection in the Earth's magnetotail
K. Schindler,J. Birn +1 more
TL;DR: In this paper, a self-consistent theory of time-dependent convection in the earth's magnetotail is developed, which is consistent with a quasi-periodic evolution of the tail, where periods of quasi-static compressional convection are followed by phases of dynamic evolution.

TL;DR: In this article, the authors used spherical double probes for measurements of electric fields on the GEOS-1, GEOS2, and ISEE-1 satellites and compared the results with measurements of plasma drift perpendicular to the magnetic field in the solar wind and the magnetosphere and the error bar for the absolute values of the electric field is found to be in the range ±(0.5-1.0) mV m-1 whereas relative variations can be determined with much better accuracy.

TL;DR: In this paper, the symmetric and asymmetric rotational discontinuities were studied by means of a one-dimensional computer simulation and by single-particle trajectory calculations, respectively, and it was shown that symmetric rotation is stable for both ion and electron senses of rotation with a thickness of the order of a few ion gyroradii.
