Abstract

Although CALET is originally designed for detections of electrons and gamma rays, nuclear components of primary cosmic rays, from protons to iron nucleus and more, are also observable by CALET, utilizing the total absorption calorimeter (TASC). TASC has 1.6 m.f.p. for protons which is enough to measure the energy of protons up to 1000 TeV. Using the observed spectra, the following items will be discussed: (1) the detailed structure of the spectrum, checking the change of the spectrum index and comparing indices of various components. More than 300 iron nuclei with the energy greater than 1 TeV/n will be observed. (2) secondary/primary ratio. Especially we can observe the both of B/C ratio and sub-Fe/Fe ratio. At the space station, the observation is free from the atmospheric contamination corrections. These observations are essential for the acceleration mechanisms and the propagation of cosmic rays.
