Effects of Na+ and He+ pickup ions on the lunar-like plasma environment: 3D hybrid modeling [PDF]
Advances in Space Research, 2012 In this report we discuss the self-consistent dynamics of pickup ions in the solar wind flow around the lunar-like object. In our model the solar wind and pickup ions are considered as a particles, whereas the electrons are described as a fluid ...

Lunar pickup ions observed by ARTEMIS: Spatial and temporal distribution and constraints on species and source locations [PDF]
Journal of Geophysical Research, 2012 ARTEMIS observes pickup ions around the Moon, at distances of up to 20,000 km from the surface. The observed ions form a plume with a narrow spatial and angular extent, generally seen in a single energy/angle bin of the ESA instrument. Though ARTEMIS has

The Acceleration of Pickup Ions
Space Science Reviews, 1996The well-established association of pickup ions with anomalous cosmic rays shows that acceleration of pickup ions to energies above 1 GeV occurs. At present, diffusive shock acceleration of the pickup ions at the termination shock of the solar wind seems to be the best candidate for acceleration to the high energies of anomalous cosmic rays, accounting

Quasilinear Relaxation of Pickup Interstellar Ions
Space Science Reviews, 1996The quasilinear relaxation of pickup interstellar helium ions is described in the diffusion shell approximation. It is shown that the Cherenkov damping of Alfven waves due to their refraction in the nonuniform solar wind could inhibit the complete relaxation of pickup helium ions over the bispherical shell.

1998
Abstract During lunar flybys in December 1994 and January 1996 pickup ions, generated by solar photons, solar wind and micrometeoroid impacts, were detected by the SMS experiment on the WIND-S/C in the energy range E = 6.5 - 226 KeV/e. Near the moon the ions have not yet reached their full pickup energy, but they can be identified by the directional ...

Ion-cyclotron wave generation by planetary ion pickup
Journal of Atmospheric and Solar-Terrestrial Physics, 2007Ion-cyclotron waves play important roles in planetary magnetospheres and are diagnostic of the processes operating in the magnetosphere and of the composition of the plasma producing the waves. At Jupiter, Io's exosphere interacts with the corotating magnetospheric plasma.

Advances in Space Research, 2004
The interaction of a comet with the solar wind starts with ion pickup. This key process is also important in other solar system contexts wherever neutral particles become ionized and injected into a flowing plasma such as at Mars, Venus, Io, Titan and interstellar neutrals in the solar wind.

Hydrogen pickup in ion nitrided steels
Materials Science and Technology, 1993AbstractUsing the energy recoil detection analysis technique, hydrogen close to the surface of ion nitrided AISI steel M2 was studied. A surface hydrogen peak was observed in all samples, with or without exposure to the glow discharge. Some bulk hydrogen was also measured in all cases; its distribution was dependent on the history of the sample.

Pickup ion energization by shock surfing
Journal of Geophysical Research: Space Physics, 1996Energization at a quasi‐perpendicular shock is described for ions which approach the shock with a speed much less than that of the incoming plasma. These ions may be trapped between the shock electrostatic potential and the upstream Lorentz force and accelerated by “surfing” along the shock surface, before eventually escaping the shock into the ...
