Cluster PEACE observations of electrons of spacecraft origin [PDF]
Annales Geophysicae, 2001 Abstract. The two PEACE (Plasma Electron And Current Experiment) sensors on board each Cluster spacecraft sample the electron velocity distribution across the full 4<pi> solid angle and the energy range 0.7 eV to 26 keV with a time resolution of 4 s.

Spacecraft potential control aboard Equator-S as a test for Cluster-II [PDF]
Annales Geophysicae, 1999 Abstract. The payload of Equator-S was complemented by the potential control device (PCD) to stabilise the electric potential of the spacecraft with respect to the ambient plasma. Low potentials are essential for accurate measurements of the thermal plasma.

Cluster spacecraft observations of a ULF wave enhanced by Space Plasma Exploration by Active Radar (SPEAR) [PDF]
, 2009 Space Plasma Exploration by Active Radar (SPEAR) is a high-latitude ionospheric heating facility capable of exciting ULF waves on local magnetic field lines. We examine an interval from 1 February 2006 when SPEAR was transmitting a 1 Hz modulation signal

Detection of a plasmaspheric wind in the Earth's magnetosphere by the Cluster spacecraft [PDF]
Annales Geophysicae, 2013 Abstract. Plumes, forming at the plasmapause and released outwards, constitute a well-established mode for plasmaspheric material release to the Earth's magnetosphere. They are associated to active periods and the related electric field change. In 1992, Lemaire and Shunk proposed the existence of an additional mode for plasmaspheric material release to

Simulation of the Cluster-Spacecraft Floating Probe Potential [PDF]
IEEE Transactions on Plasma Science, 2006 In this paper, a numerical model of the Cluster-spacecraft electric potential has been developed and validated. This model provides a good fit to the plasma density as a function of spacecraft chassis potential relative to a Langmuir probe as recorded along the Cluster-spacecraft orbit when the plasma density was between 1 and 80 cm -3 during a ...

Statistical Survey of the Terrestrial Bow Shock Observed by the Cluster Spacecraft [PDF]
Journal of Geophysical Research: Space Physics, 2019 AbstractThe terrestrial bow shock provides us with a unique opportunity to extensively investigate properties of collisionless shocks using in situ measurements under a wide range of upstream conditions. Here we report a statistical study of 529 terrestrial bow shock crossings observed between years 2001 and 2013 by the four Cluster spacecraft.

Solitary potential structures observed in the magnetosheath by the Cluster spacecraft [PDF]
Nonlinear Processes in Geophysics, 2003 Abstract. Bipolar pulses of ~ 25-100 µs in duration have been observed in the wave electric field data obtained by the Wideband plasma wave instrument on the Cluster spacecraft in the dayside magnetosheath. These pulses are similar in almost all respects to those observed on several spacecraft over the last few years.

Whistlers observed by the Cluster spacecraft outside the plasmasphere [PDF]
Journal of Geophysical Research: Space Physics, 2005 Lightning generated whistlers are ubiquitous within the plasmasphere at both high and low altitudes, and these waves propagate efficiently in both ducted and nonducted modes. On the other hand, in the magnetospheric region outside the plasmasphere, lightning‐generated whistlers are commonly observed at low altitudes (up to ∼6000 km) but only rarely at ...

Solitary waves observed in the auroral zone: the Cluster multi-spacecraft perspective [PDF]
Nonlinear Processes in Geophysics, 2004 Abstract. We report on recent measurements of solitary waves made by the Wideband Plasma Wave Receiver located on each of the four Cluster spacecraft at 4.5-6.5RE (well above the auroral acceleration region) as they cross field lines that map to the auroral zones.

Active spacecraft potential control for Cluster – implementation and first results [PDF]
Annales Geophysicae, 2001 Abstract. Electrostatic charging of a spacecraft modifies the distribution of electrons and ions before the particles enter the sensors mounted on the spacecraft body. The floating potential of magnetospheric satellites in sunlight very often reaches several tens of volts, making measurements of the cold (several eV) component of the ambient ions ...
