The CALorimetric Electron Telescope (CALET) space experiment for the direct measurement of high-energy cosmic ray spectra.
Pacini L., Stolzi F. per la Collaborazione CALET
CALET is a mission by JAXA (Japanese AeroSpace Agency), ASI (Italian Space Agency), NASA. The apparatus was launched to the International Space Station on 19 August 2015. Its main objective is to explore the region above 1 TeV with precise direct measurements of the electron+positron spectrum, nuclei spectra and gamma ray emissions. These measurements are crucial to understand the acceleration mechanism(s) of galactic cosmic rays and to search for signals from dark matter. The instrument consists of a charge detection, a finely-segmented sampling calorimeter and a homogeneous calorimeter. In this work a review of the operation status and the expected CALET performances will be discussed.
