The Heavy Ion Counter on the Galileo spacecraft will monitor energetic heavy nuclei of the elements from C to Ni, with energies from 6 to 200 MeV nucl-1. The instrument will provide measurements of trapped heavy ions in the Jovian magnetosphere, including those high-energy heavy ions with the potential for affecting the operation of the spacecraft electronic circuitry. We describe the instrument, which is a modified version of the Voyager CRS instrument. 相似文献

The Advanced Composition Explorer (ACE) mission is supported by the ACE Science Center for the purposes of processing and
distributing ACE data, and facilitating collaborative work on the data by instrument investigators and by the space physics
community at large. The Science Center will strive to ensure that the data are properly archived and easily available. In
particular, it is intended that use of a centralized science facility will guarantee appropriate use of data formatting standards,
thus easing access to the data, will improve communications within and to the ACE science working team, and will reduce redundant
effort in data processing. Secondary functions performed by the Science Center include acting as an interface between the
scientists and the mission operations team.

We present a model for composition of heavy ions in the solar energetic particles (SEP). The SEP composition in a typical large solar particle event reflects the composition of the Sun, with adjustments due to fractionation effects which depend on the first ionization potential (FIP) of the ion and on the ratio of ionic charge to mass (Q/M). Flare-to-flare variations in composition are represented by parameters describing these fractionation effects and the distributions of these parameters are presented. 相似文献
