| Research Abstract |
We have been developing the CALorimetric Electron Telescope (CALET) to search for dark matter and cosmic-ray nearby sources by observing high energy electrons and positrons on the Japanese Experiment Module of the International Space Station. The event statistics expected by the CALET observation is 100 times more than that by the balloon-borne prototype (bCALET) which had been originally scheduled. CALET is moreover capable of carrying out an observation with excellent accuracy as a space experiment. The capability for electron observation was proven by the bCALET balloon experiment, and the performance of flight model was investigated by the CERN-SPS beam test of the thermal-structure model and the simulation calculation. We have finally confirmed that the five-year mission of CALET will achieve the electron observation in the TeV region first in the world.
