چکیده

New observations of >15 MeV/nuc trapped heavy ions with Z 2 2 have been made by the SAMPEX spacecraft in low polar orbit. The composition of these ions, which are located primarily around L = 2, is dominated by He, N, 0, and Ne. The N, 0, and Ne ions are apparently trapped "anomalous cosmic rays," while the origin of the trapped He flux is presently uncertain. These ions can affect the rate of singleevent upsets (SEUs) in spacecraft hardware.

New Evidence for Geomagnetically Trapped Anomalous Cosmic Rays

We report new observations of _> 15 MeV/nuc trapped heavy ions with Z_> 2, made on the polar-orbiting SAMPEX spacecraft in late 1992 and early 1993. A trapped population that includes He, N, O, and Ne is found to be located at L -2. We conclude that the observed N, O, and Ne ions are "anomalous" cosmic rays, trapped by the mechanism proposed by Blake and Friesen. While it is not expected that t...

Ion energization in Ganymede’s magnetosphere: Using multifluid simulations to interpret ion energy spectrograms

[1] We investigate the ion population and energy distribution within Ganymede’s magnetosphere by examining Ganymede’s ionospheric outflow as a source of heavy (O) and light (H) ions and the Jovian magnetospheric plasma as an external source of heavy ions. We develop a method for examining the energy distributions of each ion species in a three-dimensional multifluid simulation in a way directly...

Observations of Gcomagnctically Trapped Anomalous Cosmic Rays by SAMPEX

The first detailed measurements of a belt of geomagnetically trapped heavy ions that originated as interplanetary anomalous cosmic rays (ACRs) are being made by the. polar orbiting satellite SAMPEX. The singly ionized interplanetary ACRs are trapped after losing electrons in the upper atmosphere. Their subsequent lifetime against energy loss by ionization of the atmosphere allows them to reach ...

Mercury s magnetosphere

The Mariner 10 observations of Mercury s miniature magnetosphere collected during its close encounters in 1974 and 1975 are reviewed. Subsequent data analysis, re-interpretation and theoretical modeling, often influenced by new results obtained regarding the Earth s magnetosphere, have greatly expanded our impressions of the structure and dynamics of this small magnetosphere. Of special interes...
