Microbeam Investigations of Presolar and Early Solar System MaterialsThis grant provided three years of funding to initiate an independent research program in Cosmochemistry at Arizona State University. Because the new equipment that was installed at ASU took longer than expected to get running, the project was extended for a fourth year with no additional funding. By the time the funds were expended, we had set up an entirely new ion microprobe laboratory at ASU, and we have been fully operational for over two years. This laboratory was funded in almost equal parts by NASA, NSF, and ASU. Papers describing the first results from this new laboratory are being published now, and the results have been making an impact on the Cosmochemistry community. While this laboratory was being built, I continued my research program in collaboration with G. J. Wasserburg at Caltech. As equipment became available, I gradually shifted my research to ASU. Over the lifetime of this grant, my research program resulted in 12 papers and 13 abstracts on topics ranging from presolar grains (2 papers, 3 abstracts), short-lived radionuclides (6 papers, 6 abstracts), chemical compositions of chondritic materials (3 papers, 3 abstracts), silicon isotopic fractionation (1 abstract), and the oxygen composition of the Sun (1 paper). The most important results of this period were the discovery of presolar hibonite in a meteorite residue, the measurement of 26A1 in CAIs from enstatite chondrites, and the measurements of 10Be in type A CAIs from CV chondrites. All of these results have had a significant impact on research in Cosmochemstry.
