| Research Abstract |
In joint research with Chinese colleagues, we study high-energy cosmic rays/gamma rays by means of an air shower array(called Tibet-III, 37,000m2 in area) set up at Yangbajing(4,300m above sea level), Tibet, China. In this research program, a large underground muon detector is constructed to improve the Tibet-III sensitivity to cosmic gamma rays. Furthermore, various researches are made on cosmic rays and cosmic gamma rays including highest-energy cosmic rays by means of Tibet-III.
