The CALorimetric Electron Telescope (CALET) is a Japanese-led international space mission by JAXA (Japanese Aerospace Exploration 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 (CGBM), operates as a gamma-ray burst monitor using two different kinds of scintillators to detect photons from 7 keV to 20 MeV. 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 LIGO GW 151226 gravitational wave event will be presented too
