PEACE: A PLASMA ELECTRON AND CURRENT EXPERIMENT
An electron analyser to measure the three-dimensional velocity distribution of electrons in the energy range from 0.59 eV to 26.4 keV on the four spacecraft of the Cluster mission is described. TheExpand

The Cassini CAPS Electron Spectrometer
One of the major aims of the Cassini spacecraft is to characterize in detail the interaction of the solar wind with the Saturnian system. The Cassini Plasma Spectrometer (CAPS) addresses this aim byExpand

The Toroidal Imaging Mass-Angle Spectrograph (TIMAS) for the polar mission
The science objectives of the Toroidal Imaging Mass-Angle Spectrograph (TIMAS) are to investigate the transfer of solar wind energy and momentum to the magnetosphere, the interaction between theExpand

Charge neutrality and ion conic distributions at the equatorward electron edge of the midaltitude cusp
We have investigated the physical processes occurring in order to maintain charge neutrality at the equatorward edge of the cusp by examining data from 200 Polar cusp crossings. The significantExpand

VELOCITY SPACE DIFFUSION OF PICKUP IONS FROM THE WATER GROUP AT COMET HALLEY
The authors have studied the diffusion in velocity space of cometary ions using the distributions of ions measured by the implanted ion spectrometer on Giotto during the inbound pass. TheExpand

An active current sheet in the solar wind
The supersonic solar wind possesses a variety of simple small scale (<10-min observation duration) phenomena, including discontinuities1–3 and magnetic holes4,5. We report here recent AMPTE-UKS6Expand

Bulk properties and velocity distributions of water group ions at Comet Halley - Giotto measurements
In the region upstream of comet Halley, pickup heavy ions of cometary origin were directly observed by the Implanted Ion Spectrometer on Giotto. Here we discuss diffusion of this population in pitchExpand

The temporal evolution of electron distributions and associated wave activity following substorm injections in the inner magnetosphere
The temporal evolution of electron distributions and associated wave activity following substorm injections in the inner magnetosphere are investigated using data from the CRRES satellite. EquatorialExpand
