Propagation of lower‐band whistler‐mode waves in the outer Van Allen belt: Systematic analysis of 11 years of multi‐component data from the Cluster spacecraft

, 2014
Lower‐band whistler‐mode emissions can influence the dynamics of the outer Van Allen radiation belts. We use 11 years of measurements of the STAFF‐SA instruments onboard the four Cluster spacecraft to systematically build maps of wave propagation ...

Cusp observations during a sequence of fast IMF B_Z reversals [PDF]

Annales Geophysicae, 2009
In recent years, a large number of papers have reported the response of the cusp to solar wind variations under conditions of northward or southward Interplanetary Magnetic Field (IMF) Z-component (BZ).

ECLAT Cluster Spacecraft Magnetotail Plasma Region Identifications (2001–2009)

, 2014
The European Space Agency’s four-spacecraft Cluster mission has been observing the Earth’s dynamical magnetotail region since early 2001. The magnetotail, and in particular the hot trapped plasma sheet, is a critical region in the coupled Sun-Earth ...

Intermittent energy dissipation by turbulent reconnection [PDF]

, 2016
Magnetic reconnection—the process responsible for many explosive phenomena in both nature and laboratory—is efficient at dissipating magnetic energy into particle energy.

IMPALAS: Investigation of MagnetoPause Activity using Longitudinally-Aligned Satellites—a mission concept proposed for the ESA M3 2020/2022 launch [PDF]

, 2012
The dayside magnetopause is the primary site of energy transfer from the solar wind into the magnetosphere, and modulates the activity observed within the magnetosphere itself.

The Cluster Magnetic Field Investigation: overview of in-flight performance and initial results [PDF]

Annales Geophysicae, 2001
The accurate measurement of the magnetic field along the orbits of the four Cluster spacecraft is a primary objective of the mission. The magnetic field is a key constituent of the plasma in and around the magnetosphere, and it plays an active role

DEMON: a Proposal for a Satellite-Borne Experiment to study Dark Matter and Dark Energy [PDF]

, 2006
We outline a novel satellite mission concept, DEMON, aimed at advancing our comprehension of both dark matter and dark energy, taking full advantage of two complementary methods: weak lensing and the statistics of galaxy clusters.

Spacecraft potential control for Double Star [PDF]

Annales Geophysicae, 2005
The spacecraft potential of Double Star TC-1 is positive in large parts of the orbits due to the photo-effect from solar EUV irradiation. These positive potentials typically disturb low energy plasma measurements on board. The potential can be reduced,

Spatial scales of the magnetic ramp at the Venusian bow shock [PDF]

Annales Geophysicae, 2011
Typically multi-spacecraft missions are ideally suited to the study of shock spatial scales due to the separation of temporal and spatial variations. These missions are not possible at all locations and therefore in-situ multi-spacecraft measurements ...
