The CALorimetric Electron Telescope (CALET) mission is proposed for the observation of various
components of cosmic-rays as well as γ-rays on the Exposure Facility of the Japanese Experiment Module
on the International Space Station. The detector is composed of an imaging calorimeter of scintillating
fibers (IMC), a total absorption calorimeter of BGO (TASC) and a silicon pad module at the top of IMC .
The total thickness of absorber is 36 r.l for the electromagnetic particles and 1.8 m.f.p for protons. The
total weight of the payload, including the detector, the support, the interface instruments with JEM so on, is
nearly 2,500 kg and the geometrical factor for the electrons is about 1 m2 sr. The CALET has a unique
capability to measure electrons and γ-rays beyond 1 TeV since the hadron rejection power is 106. The
energy resolution for the electro-magnetic particles is better than a few % above 100 GeV. The detector is optimally designed to detect any change in the energy spectra caused by physical processes, or a line
signature in the energy distribution expected from annihilations of dark matter candidates. This paper is the
first presentation by the international team of the CALET collaboration.
