Research Abstract

A study of high-energy cosmic rays has been continued using the air shower array at Yangbajing (4300 m above sea level) in Tibet. The present array (Tibet-III AS array), completed in the late fall of 2004, consists of about 800 scintillation counters of each 0.5 m^2 which are placed on a lattice with 7.5m spacing, covering about 37,000m2. From this experiment, we obtained new results on the gamma-ray emission from the Crab Nebula and other sources, all-particle energy spectrum of primary cosmic rays in the wide energy range of 2×10^14 -10^17 eV, sidereal anisotropy of 10-TeV cosmic-ray intensity and yearly variation of the Sun's shadow by Galactic cosmic rays.
