The CALorimetric Electron Telescope (CALET) space experiment for the direct measurement of high energy electrons in cosmic rays

The CALorimetric Electron Telescope (CALET) is a Japanese-led international space mission by JANA (Japanese Aerospace Exploraticai Agency) in Collaboration with the Italian Space Agency (ASI) and 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 and nuclei spectra. The instrument consists of a charge detection device composed of two layers of plastic scintillators, a finely-segmented sampling calorimeter with scintillating fibers (3 radiation lengths) and a homogeneous calorimeter made of PWO scintillating bars (27 radiation lengths). In parallel with the calorimeter another instrument, the CALET Gamma-ray Burst Monitor (CCBM), operates as a gamma-ray burst monitor using two different kinds of scindilators to detect photons from 7 keV to 20 51eV. In this work a brief review of the electron analysis Will be discussed focusing on the electron/proton discrimination power estimated with different Monte Carlo simulations. Some published results about calibration and search for electromagnetic counterparts of the LIG G-V 151226 gravitational wave event will be presented too.
