| Outline of Final Research Achievements |
Recent imaging atmospheric Cherenkov telescope systems are known to be capable of measuring energy spectrum of cosmic-ray heavy components in sub-PeV region by detecting Direct Cherenkov photons emitted by nuclei at the upper atmosphere. In this study, we performed Monte Carlo (MC) simulation of comic-ray nuclei events for the next generation ground-based gamma-ray telescope system CTA (Cherenkov Telescope Array). By analyzing Direct Cherenkov events in the MC simulation data, we estimated the capability of CTA (charge resolution and expected event count rate) for the measurement of cosmic-ray chemical composition around PeV.
