Extended Energy Spectrum Measurement of Elements With the Cosmic Ray Isotope Spectrometer (CRIS)
Abstract
We describe a multiple dE/dx technique used to identify particles that penetrate through the bottom of the CRIS instrument, significantly extending the measured energy ranges for major elements beyond that for stopping particles. In preliminary analysis, the upper energy limit for oxygen has been extended from ∼240 MeV/nuc for stopping particles to ∼410 MeV/nuc for penetrating particles, and the upper energy limit for iron has been extended from ∼470 MeV/nuc to ∼670 MeV/nuc. We report new element intensities in these extended energy ranges, and compare them with previously reported intensities and with spectra derived using cosmic ray transport and solar modulation models.
