The origin of the highest energy cosmic rays (≥1020 eV) is not well understood. Interesting models called "top-down" scenarios have been proposed to explain the origin. The γ-ray flux in ultra-high-energy cosmic rays is a key parameter for giving

The data acquisition system of the Akeno Giant Air Shower Array (AGASA) is described. The AGASA array covers an area of about 100 km2 and has been operated since 1990 to study the origin of extremely high energy cosmic rays. In the early stage of our
