Description
The Calorimetric Electron Telescope (CALET) is a cosmic-ray observatory operating since October 2015 aboard the International Space Station (ISS). The primary scientific goal of the CALET mission is to perform a high-precision measurement of the inclusive spectrum of cosmic electrons and positrons up to about 20 TeV, where the shape of the spectrum might indicate the presence of nearby cosmic-ray sources or dark matter signatures. The CALET mission is also able to investigate the mechanism of cosmic-ray acceleration and propagation in the Galaxy, by performing direct measurements of the energy spectra and elemental composition of cosmic-ray nuclei from H to Fe and the abundance of trans-iron elements, up to Zr (Z = 40), in the energy range reaching the PeV scale. Finally, CALET can monitor the gamma-ray sky up to about 10 TeV, search for signals from gravitational-wave event candidates, and observe gamma-ray burst events. The CALET detector, consisting of a charge detector, an imaging calorimeter and a total absorption calorimeter has a total thickness of about 30 radiation lengths at normal incidence. The instrument can achieve a clear separation between hadrons and electrons and between charged particles and gamma-rays. In this contribution we summarize the most recent results obtained from data processed since the beginning of the mission, by focusing on the measured spectra of cosmic-ray proton, Helium and Boron, the latter flux compared with that of Carbon to investigate the secondary-to-primary abundance ratio B/C.
