TL;DR: 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.

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.

TL;DR: The Rosetta dual Langmuir probe instrument (LAP) as mentioned in this paper utilizes the multiple powers of a pair of spherical LAP probes for measurements of basic plasma parameters with the aim of providing detailed knowledge of the outgassing, ionization, and subsequent plasma processes around the Rosetta target comet.

TL;DR: In this paper, it is argued that such a model seems inapplicable, at least in its simplest form, by providing a timescale and a length scale which are not in agreement with observations.

TL;DR: In this article, the authors provide a survey of the conditions for occurrence and spatial distributions of wave-filled cavities in the frequency region of lower hybrid wave packets and the basic properties of individual cavities and associated fluctuating electric fields.
