Solar wind noble gases - Preliminary results from bulk metallic glass flown on Genesis

The solar wind (SW) is the major source of information to study the solar composition of volatile elements. It provides insights about the Sun's present state, its evolution and the composition of the proto-solar nebula. SW noble gases can be used to study processes causing fractionation between the Sun and the SW. Moreover they are useful to determine compositional variations for distinct SW energy regimes including the high energy SEP component apparently abundant in lunar samples [I]. We will present noble gas data collected on Genesis [2] with a bulk metallic glass target (BMG) [3].
