概要	K.Yoshida, S.Torii, T.Tamura, K.Kasahara, J.Chang, H.Fuke , K.Hibino, M.Ichimura, T.Kashiwagi, Y.Katayose, H.Kitamura, T.Kobayashi, Y.Komori, S.Kuramata, F.Makino, K.Mizutani, H.Murakami, J.Nishimura, S.Okuno , Y.Saito, M.Shibata, M.Takayanagi, N.Tateyama, T.Terasawa, S.Tomida, Y.Uchihori, S.Ueno, T.Yamagami, T.Yuda We are proposing the CALET (CALorimetric Electron Telescope) for the observation of high-energy electrons and gamma rays at the Exposed Facility of the Japanese Experiment Module on the International Space Station. The CALET has a capability to observe electrons (+positrons) in 1GeV-10TeV and gamma rays in 20MeV- 10TeV with a high energy resolution of 2%@100GeV, an angular resolution of 0.06deg@100GeV, and a high proton rejection power of 10⁶. CALET has the geometrical factor of nearly 1m² sr and three-years observation is expected. Precise electron observation of CALET enables us to identify cosmic-ray electron sources by the detection of distinctive features in the energy spectrum and anisotropy toward nearby sources. The ISS orbit enables CALET to survey all of the sky in a wide field of view of 2 sr without attitude control of the instrument. In addition, by the hybrid observations of high-energy electrons and gamma rays, the CALET can search for WIMP dark matter.
