Facilities
1. Isotope Geochemistry
Laboratory, Field Museum
The Isotope Geochemistry Laboratory (IGL, established 2001) at The Field Museum features a Micromass Isoprobe multicollector plasma mass spectrometer with 9 faraday and three ion counting detectors. Sample introduction systems include a Cetac Aridus desolvating nebulizer for solution analysis and a New Wave UP193 excimer laser ablation system for in-situ analysis of mineral phases. The laboratory also features a 750 sq. ft. class 1000 clean chemistry laboratory for mineral separation, sample digestion and elemental separation. Chemical separation and mass spectrometry techniques established at the IGL thus far include those for the measurement of Mg, Fe, Ni, Sr, Nd, Hf, W and Pb isotope ratios.
2. Chicago-Argonne
Resonant Ionization Spectrometer (CHARISMA), Argonne National Laboratory
The Chicago-Argonne Resonant
Ionization Spectrometer for MicroAnalysis (CHARISMA) at Argonne National
Laboratory has been providing detailed analyses of presolar stardust grains
since 1997. The isotopic composition of heavy
elements in individual stardust grains is a clue to the nucleosynthesis conditions
in stars. These analyses are challenging because
1) the grains are very small, the largest being perhaps a few microns in
diameter, 2) they contain only trace (ppm) concentrations of heavy elements
and 3) isobaric interferences must be strongly suppressed.
The CHARISMA instrument uses a microfocus laser to resolve individual
grains, and tunable lasers to discriminate the element of interest from the
other elements present in the grains. For overviews
of the instrument and its impact on the study of presolar grains see Savina
et al., Geochim. et Cosmochim. Acta 67, 3215-3225 (2003), and
Lugaro et al., Astrophys. J. 593, 486-508 (2003).

Conferences
Nuclei in the Cosmos VIII, Vancouver, Canada (July 19-23 2004). At this conference, Mike Savina reported on the first discovery of excess p-isotopes for Mo and Ru in presolar SiC grains, Andy Davis showed new predictions for s-process nucleosynthesis in AGB-stars, Nicolas Dauphas demonstrated how the extinct radionuclide 92Nb can be used to constrain the contribution of rp-nucleosynthesis in X-ray bursts to the cosmic abundances, and Arthur Cole reported on his search of supernovae grains in ice cores.
