Outline of Final Research Achievements

A cosmic-ray detector, CALET, was launched in August 2015. It is successfully observing cosmic-ray electrons, gamma-rays, and nuclei on the International Space Station. Performances of the detector for the high energy cosmic rays are estimated by simulations for interactions of particles in the detector. Thus, it is very important to verify the simulations by beam tests. Therefore, we carried out heavy ion beam tests at CERN-SPS with a ground verification model which we assembled with Structure Thermal Models, Bread Board Models of readout electronics, and self-made electronics circuits equivalent to Flight Models. We could confirm that the simulations were consistent with the beam data.
