Two Important R&D Projects at CERN 

The CAS delegation headed by President Lu Yongxiang visited CERN on December 12, 2004. Among members of the delegation was Professor Chen Hesheng, Director of our Institute. CERN is the largest particle physics lab in the world, with its 20 member countries from Europe. Each year more than 7,000 scientists and engineers from 80 countries in the world come to CERN for the study of frontier particle physics. The scientific exchange between Chinese scientists and their CERN counterparts began in the late 1950's. The recent 20 years have witnessed swift development of the bilateral collaboration. The Chinese Academy of Sciences and the Ministry of Science and Technology have signed long-term cooperative agreements with CERN, which constitute the key components of scientific and technological cooperation between China and Europe. CERN has provided China with valuable support in the construction of the latter's accelerators, as well as the development of Internet and WWW whereas Chinese scientists have made many important contributions to the scientific research of CERN.

General Director R. Aymar of CERN briefed the CAS delegation on the scientific research projects, with the focus on the progress of the Large Hadron Collider (LHC) to be operated in 2007. This large cross-century international cooperative science project will realize the proton-proton collison at the center-mass-of-enengy of 14 TeV to probe the important issues of frontier particle physics in the world. The CAS delegation visited the LHC, the experimental halls of ATALAS and CMS, the hall for testing superconducting magnets and the laboratory of lead tungsten testing and assembling for CMS experiment, which are all under construction. Our Institute has made important contributions in the construction of ATLAS and CMS detectors. Aymar spoke highly of the collaboration with Chinese scientists.

General Director Aymar also introduced to the CAS delegation two important R & D projects being carried out - the Compact Linear Collider (CLIC) and the Superconducting Proton Linac (SPL) and expressed his warm welcome for Chinese scientists to join in the collaboration.
