"CALET: direct cosmic ray measurements on the International Space Station."

CALET was installed on the Japanese Experiment Module “Kibo” of the International Space Station in August 2015, and started direct cosmic ray observation in the TeV region. The primary science goal of the CALET mission is to investigate possible nearby sources and search for dark matter signatures. CALET will measure the flux of cosmic ray electrons to 20 TeV, gamma-rays to 10 TeV and nuclei with Z=1~40 up to several 100 TeV. CALET has an imaging and a thick calorimeter, which provides excellent energy resolution and particle identification. Science objectives, capabilities and performance of CALET are presented in this talk.
