| Research Abstract |
In order to study extremely high energy phenomena in the Universe, such as AGN jets, colliding galaxies and internal shocks in galaxy clusters, we developed ahuge air shower detector to measure extremely high energy cosmic rays and determinedtheir arrival directions, energies and species in Utah, USA, and we operate this detectorfrom 2008 with a collaboration of research activities from Japan, USA, South Korea andRussia. In this research, we developed a "standard candle" for the air shower detector's energy calibrations, which is a portable UV laser on a steering mount. This UV laser light source was completed and confirmed to have enough systematic accuracies. The full-scaleoperations will be started in step with a linear accelerator in the experimental site.
