The CALET Project for Investigating High Energy Universe
Abstract
The CALorimetric Electron Telescope, CALET, mission is proposed for the Japanese Experiment Module Exposed Facility, JEM-EF, of the International Space Station. The mission goal is to reveal high-energy phenomena in the universe by carrying out a precise measurement of the electrons in 1 GeV - 10 TeV and the γ-rays in 20 MeV - several TeV. The CALET has a unique capability to measure the electrons and gamma-rays over 1 TeV since the hadron rejection power might be as much as ∼106 and the energy resolution of electromagnetic particles better than a few % over 100 GeV. Therefore, it is promising to detect the change of energy spectra and the γ-ray line expected from candidates of the dark matter. We are expecting to launch the CALET around 2012 by the Japanese H-II Transfer Vehicle, HTV, and to observe for three years.
