Results of the Heavy Cosmic-Ray Analysis with CALET on the International Space Station

The study of the spectral behavior of charged cosmic-ray elements is of particular interest to gain a deeper understanding of propagation and acceleration phenomena in our Galaxy. The Calorimetric Electron Telescope (CALET), launched to the International Space Station in 2015, provides more than 7 years of continuous observation of high energy cosmic rays up to ∼1 PeV. CALET can measure cosmic-ray charge up to Z = 40 and, with its 27 radiation lengths deep Total Absorption Calorimeter, it measures particle energy, allowing for the determination of spectra up to nickel. In this contribution we present a direct measurement of several charged nuclei spectra from boron to nickel, including the boron to carbon and the nickel to iron ratios. Also, the ultra heavy nuclei analysis results are reported.
