概要 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.
