Description
Summary:In recent years, the AMS system at the Nuclear Science Laboratory of the University of Notre Dame has introduced a series of upgrades which have dramatically increased the capabilities for the measurement of trace radionuclides. These upgrades have solved issues with isotopic selectivity in the injection system, allowed for the measurement of heavier radionuclides, and improved the quality of both ion beams and the data obtained with them. The specifics of the installed equipment, as well as preliminary results on isotopic sensitivities for previously measured and newly-developed radionuclides, are discussed. Finally, the impacts on the development of planned radionuclide measurements in the future, including measurements of the actinides, will be mentioned.
