Solar wind Mg, Cr and Fe abundances in diamond-like carbon collector from Genesis mission

The chemical composition of the Sun provides the reference standard for a wide variety of astronomical, cosmochemical and geochemical studies. To better determine the solar composition, the Genesis spacecraft collected solar wind at the L1 point in space for 27 months from December 2001 to April 2004. Prior SIMS analyses of Genesis samples have found discrepant results for the Mg and Fe solar wind fluences from different collector materials (Burnett et al., 2007).
