Simulation study on high energy electron and gamma-ray detection with CALET
Abstract
High energy electron detection is very important to understand the cosmic ray origin, acceleration, and propagation. Until now only tens electron above 1 TeV have been observed. The CALorimetric Electron Telescope (CALET) will perform a direct measurement of electron and gamma-ray up to an energy of 10 TeV. Its advanced design employs an imaging calorimeter and a total absorption calorimeter. The proton rejection power for electrons is nearly 1000,000 with the detector thickness 35 r.l. by using the shower difference between electrons and hadrons, it is enough to observe electron up to 10 TeV with high precision. In this work, we present the Monte Carlo simulation results on high energy electron and gamma-ray detection with CALET.
