    Abstract

    The CALorimetric Electron Telescope, CALET, is a new all-sky gamma-ray and electron observatory being developed for the Exposure Facility of Japanese Experiment Module (JEM-EF) on the International Space Station (ISS). The mission goal is to investigate high-energy universe by observing cosmic-ray electrons in 1 GeV - 20 TeV, gamma rays in 20 MeV - 10 TeV, and protons, heavier nuclei in several 10 GeV - 1 PeV. The main instrument consists of an imaging calorimeter of scintillating fibers, IMC, and a total absorption calorimeter of BGO, TASC. CALET has a unique capability to observe highenergy electrons and gamma rays with an energy resolution better than a few % above 100 GeV, an angular resolution of 0.1 deg above 100 GeV, a wide field of view of around 1.8 sr, and a hadron rejection power larger than 105. This capability enables us to search for nearby cosmic-ray sources, dark matter, and survey the variable gamma-ray sky.
