Missions of CSTNET in CNGI

• The access of IPv6 network for 100 disciplinary research networks and institutesDisciplinary research networks : about 30 networks cover

many specific areas, most of them in Beijing Institutes: more than 60 institutes around china, most of the

m are institutes in CAS• Beijing, Shanghai,Guangzhou • Shenyang, Chuangchun, Chendu, Lanzhou• Xian, Nanjing, Xinjiang, Wuhan, Kunming, Hefei

• Connection BandwidthAt Least 1G (1G/10G)

• Circuit Resource: Optical Fiber are provided in Beijing and Local Connection in Sub-center for further expansibility

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 th

e antiproton/proton ratio by cosmic ray moon shadow.

ITER Project

• What is ITER? ITER is a joint international research and de

velopment 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 pur

poses".
