| Research Abstract |
We studied the performance of cosmic-ray detector CALET and calibrated it with the CERN-SPS accelerator. We made analyses of energy deposits in each detector layer, reconstruction of shower axes, and separation of electrons and protons. As a result, we obtained energy resolutions, angular resolutions, and rejection powers against protons. We compared them with simulated results, and it improved our understanding of the simulations which would be indispensable for data analyses of a flight model.
