The CALorimetric Electron Telescope, CALET, is a versatile detector for exploring the high energy universe, planned to be placed on the Japanese Experiment Module Facility of the International Space Station, ISS. CALET is designed to perform direct measurements of electrons from 1 GeV to 20 TeV, gamma-rays from 10 GeV to 10 TeV, and protons and nuclei from several 10 GeV to 1000 TeV. The main detector consists of a Charge Detector (CHD), an Imaging Calorimeter (IMC), and a Total Absorption Calorimeter (TASC). The total thickness of the calorimeter is 30 X0 for electromagnetic particles or 1.3 λ for protons. We have been carrying out Monte Carlo simulations with EPICS to study the CALET performance. With its imaging and deep calorimeter, CALET provides excellent proton rejection, ∼ 105, and a high energy resolution, ∼2%, over 100 GeV for electromagnetic particles, which make possible the observation of electrons and gamma-rays into the TeV region. In this paper, we will present the expected performance in observing the different particle species, including the geometric factor, the trigger efficiency, the energy resolution and the particle identification power.
