China is to input 640 million yuan in coming five years to highly improve the performance of Beijing electron-positron collider (BEPC), a landmark project of the nation's science and technology.

In coming five years or a longer time, the luminosity of BEPC will be with double ring-scheme, i.e. to carry a workload equivalent to that of 100 days as did in the past, according to Chen Hesheng, director of the Institute of High Energy Physics, Chinese Academy of Sciences (CAS). Chen added that since in-depth studies in high energy physics needs plenty of digital data, lifted luminosity will provide much more data needed and realize precise measurement so as to lay a foundation for important discoveries and achievements.

As a key project of the state, the electron-positron collider realized its first successful collision on October 16, 1988, and thus became another great achievement in the hi-tech field following A-bomb, H-bomb and satellite.

The BEPC is applied to both studies for high energy physics (HEP) and synchrotron radiation (SR), the device of the latter being a large research platform open to the public, and the improved SR energy will provide stronger means for probing into the structures of protein and nanometer.
