| 概要 | CALorimetric Electron Telescope, CALET, is a new observatory to be placed on the International Space Station. Major scienti c objectives are to search nearby cosmic ray sources and dark matter signatures by carrying out accurate measurements of cosmic ray electrons in 1 GeV - 20 TeV and gamma-rays in 4 GeV - 10 TeV. Since proton background is very large, high proton rejection power is mandatory for high energy electron and gamma-ray measurements. CALET has an imaging and deep calorimeter with 30 X0 for electromagnetic particles, which provides high proton rejection and excellent energy resolution. We have been carrying out Monte Carlo simulations to study the detector performance and acceleration beam tests at CERN-SPS to assess the validity of our simulations. In this paper, we present measured performance of particle identi cation such as electron/proton separation and electron/gamma-ray separation compared to the simulation results, and expected spectra of electron and gamma-ray observed by CALET. |
