  8. Applications • Focus • Sharing Scientific Data • Sharing Scientific Equipment • Cooperation on research projects • Improve research methods with digitalization, Informatization • Most interesting areas • High Energy Physics • Astronomy • Bioscience • Geo Science • Environment • Atmosphere

  9. ITER Project • What is ITER? ITER is a joint international research and development project that aims to demonstrate the scientific and technical feasibility of fusion power. The partners in the project - the ITER Parties - are the European Union (represented by EURATOM), Japan, the People´s Republic of China, India, the Republic of Korea, the Russian Federation and the USA. ITER will be constructed in Europe, at Cadarache in the South of France. • Goal of ITER demonstrate the scientific and technological feasibility of fusion power for peaceful purposes".

  10. International Cosmic RayPre-Process Center • YBJ International Cosmic Ray Observatory is located at 90°26'E and 30°13'N in Yangbajing (YBJ) valley of Tibetan highland. The ARGO -YBJ Project is a Sino-Italian Cooperation started its detector installation in 2000. It aims at the research of the origin of high energy cosmic rays. It explores the approximately 100 GeV uncultivated land and measuring the antiproton/proton ratio by cosmic ray moon shadow. • ARGO RPC carpet project • 10000+ detectors • raw data: 200TB/year • reconstruction data: 20TB/year • computing power: 400+ CPUs Cosmic ray air-shower array detector China-Japan CollaborationYangbajing , Tibet 4300m a.s.l.
