Abundances and charge states of particles in the solar wind
The Sun is the only star from which matter can be collected in order to investigate its elemental and isotopic composition. Solar elemental abundances pro- vide the most important benchmark for theExpand

Global Observations of the Interstellar Interaction from the Interstellar Boundary Explorer (IBEX)
What's Happening in the Heliosphere The influence of the Sun is felt well beyond the orbits of the planets. The solar wind is a stream of charged particles emanating from the Sun that carves a bubbleExpand

Solar Wind Neon from Genesis: Implications for the Lunar Noble Gas Record
Lunar soils have been thought to contain two solar noble gas components with distinct isotopic composition. One has been identified as implanted solar wind, the other as higher-energy solarExpand

Neon-20, oxygen-16, and helium-4 densities, temperatures, and suprathermal tails in the solar wind determined with WIND/MASS
Measurements from the MASS instrument on the WIND spacecraft from late Dec. 94 through Aug. 95 are reported for 20Ne, 16O, and 4He. The average 4He/20Ne density ratio is 566±87 with considerableExpand

Solar wind measurements with SOHO: The CELIAS/MTOF proton monitor
The proton monitor, a small subsensor in the Charge, Element, and Isotope Analysis System/Mass Time-of-Flight (CELIAS/MTOF) experiment on the SOHO spacecraft, was designed to assist in theExpand

The helium isotopic ratio in the solar wind and ion fractionation in the corona by inefficient Coulomb drag
Using data obtained between 1991 and 1996 with the SWICS instrument (Solar Wind Ion Composition Spectrome- ter) aboard the Ulysses spacecraft, a long time average of the ( 4 He= 3 He) isotopic ratioExpand

Minor ions in the solar wind
Ions heavier than 4He are treated as “minors” in the solar wind. This is justified for many applications since minor ions have no significant influence on the dynamics of the interplanetary plasma.Expand

Solar Parameters for Modeling the Interplanetary Background
The goal of the working group on cross-calibration of past and present ultraviolet (UV) datasets of the International Space Science Institute (ISSI) in Bern, Switzerland was to establish aExpand

Solar wind helium isotopic composition from SWICS/ULYSSES
This is the first study of the isotopic composition of solar wind helium with the SWICS time-of flight mass spectrometer. Although the design of SWICS is not optimized to measure3He abundancesExpand

MEASUREMENT OF 3 He/ 4 He IN THE LOCAL INTERSTELLAR MEDIUM: THE COLLISA EXPERIMENT ON MIR
An accurate measurement of the noble gas isotopic composition in the local interstellar medium (LISM) provides a constraint of primary importance for modeling Galactic evolution and, in some cases,Expand
