The Isotopic Composition of Cosmic Ray Nuclei Beyond the Iron Peak

Abstract

Isotope measurements of cosmic ray nuclei beyond the Fe peak are considered, using the charge region from Z=29 to Z∼40 as an example. Such studies can address a number of important questions that bear on cosmic ray origin, acceleration, and propagation. One possible approach for measuring isotopes with Z≥30 is based on large‐area arrays of silicon solid state detectors combined with scintillating optical fiber trajectory detectors optical fiber trajectory detectors.
