Energy Spectra and Relative Abundances of Heavy Cosmic-ray Nuclei around 1 TeV/nucleon

摘要

We describe a measurement of the intensities of heavy primary cosmic-ray nuclei with the Transition Radiation Array for Cosmic Energetic Radiation(TRACER)up to energies around a few TeV/nucleon.Absolute cosmic-ray fluxes are presented for O,Ne,Mg,Si,and Fe obtained during a one-day test flight from Ft.Sumner,NM in preparation for a 20-day circum-polar balloon flight.The results of TRACER are largely consistent with previous observations in this energy range.
