CALET measurements of cosmic nuclei on the ISS and performance of charge identifiers.
Abstract
CALET (CALorimetric Electron Telescope) is a calorimetric electron telescope in preparation for a launch to the International Space Station (ISS), where it will perform long term observations of electrons, nuclei and gamma-rays. The instrument includes a two-layered Charge Detector (CHD) module and an Imaging Calorimeter (IMC) to provide a measurement of the electric charge of individual nuclear species from proton to iron and trans-iron elements followed by a total absosorption calorimeter to measure the event energy. CALET will be able to perform precision measurements of individual element spectra and of the energy dependence of secondary/primary abundance ratios. In this paper, we will review the main physics goals for CALET's measurements of nuclei,the expected performance of the charge detectors and the results of a prototype test with a fragmented beam of relativistic ions that took place at the SPS of CERN in January 2013.
