Measurements of the Elemental Composition and Energy Spectra of Anomalous Cosmic Ray Nuclei by the Solar Isotopic Spectrometer on ACE

The Solar Isotope Spectrometer (SIS) instrument on the Advanced Composition Explorer (ACE) spacecraft provides high resolution measurements of the elemental and isotopic compositions of energetic nuclei between approximately 10 and 100 Me V /nucleon from He to Zn (Z = 2 to 30). Solar quiet times from late 1997 to the present will be used to measure the energy spectra of elements previously observed in the anomalous cosmic rays, as well as search for new, rare elements. Relative abundances of the observed species will also be derived and related to the abundances of neutral atoms in the local interstellar medium.
