Detected Abundances of Nuclei Relative to <sub>26</sub>Fe for Elements <sub>14</sub>Si through <sub>44</sub>Ru with CALET on the International Space Station
Abstract The Calorimetric Electron Telescope (CALET), launched to the International Space Station (ISS) in 2015 August and continuously operating since, measures cosmic-ray (CR) electrons, nuclei, and gamma rays. CALET, with its 27 radiation length deep Total Absorption Calorimeter, measures particle energy and allows for the measurement of spectra, secondary to primary ratios of the more abundant CR nuclei through 28 Ni, while the main charge detector can measure ultra-heavy CR nuclei through 44 Ru. The results for the abundances of elements from Z = 14 to Z = 44 relative to 26 Fe over 7.5 yr of observation are presented here and compared to previous measurements from ACE-CRIS, SuperTIGER, and HEAO-3.
