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.
