The electron drift instrument (EDI) on Cluster pioneered a new method of measuring electric fields, using a beam of electrons to sample the drift velocity over a km��scale gyro orbit. The technique is especially well suited to measuring weak,

EDI measures the drift velocity of artificially injected electron beams. From this drift velocity, the perpendicular electric field and the local magnetic field gradients can be deduced when employing different electron energies. The technique requir

We present the first triangulation measurements of electric fields with the electron drift instrument (EDI) on Equator-S. We show results from five high-data-rate passes of the satellite through the near-midnight equatorial region, at geocentric dist

We present the first electron time-of-flight measurements obtained with the Electron Drift Instrument (EDI) on Equator-S. These measurements are made possible by amplitude-modulation and coding of the emitted electron beams and correlation with the s

Publikováno v: Space Science Reviews. 79:233-269

The Electron Drift Instrument (EDI) measures the drift of a weak beam of test electrons that, when emitted in certain directions, return to the spacecraft after one or more gyrations. This drift is related to the electric field and the gradient in th

Hydra ? A 3-dimensional electron and ion hot plasma instrument for the POLAR spacecraft of the GGS mission

Publikováno v: Space Science Reviews. 71:459-495

HYDRA is an experimental hot plasma investigation for the POLAR spacecraft of the GGS program. A consortium of institutions has designed a suite of particle analyzers that sample the velocity space of electron and ions between ≃2 keV/q – 35 keV/q

Magnetic field-aligned electrodynamics of Alfvén/ion cyclotron waves

Publikováno v: Journal of Geophysical Research: Space Physics. 98:19435-19441

We report on the first experimental determination of the magnetic field-aligned electric field (E∥) of an Alfven/ion cyclotron (A/I) wave. The wave was observed propagating in the geostationary regions of the Earth's magnetosphere with a frequency

Plasma Injection Processes

Autor: Carl E. McIlwain

Publikováno v: Journal of geomagnetism and geoelectricity. 43:193-203

A. Schmidt surmised in 1924 that geomagnetic storms caused the build up of an external ring current. Ever since, there have been speculations about the nature of the responsible mechanisms. Direct observations of plasma injection into closed field li
