Brief Introduction of Professor Hesheng Chen

Hesheng Chen is an academician of Chinese Academy of Sciences, a particle physicist. He graduated from Peking University in 1970 and received his PhD of Physics at Massachusetts Institute of Technology 1984. He was the director of the Institute of High Energy Physics of Chinese Academy of Sciences from 1998 to 2011. He was elected as Chairman of the Asian Committee for Future Accelerators. He is currently the Director of BEPC National Laboratory of IHEP and Project Manager of the China Spallation Neutron Source.

His area of research is particle physics experiments. He worked at Mark-J Experiment of DESY for the gluon jet study and the precision tests of the electroweak theories from 1979 to 1986. Since 1983 he worked at the L3 experiment of CERN for the physics proposal and detector design, Monte Carlo simulation and Tau physics, and made contributions to the precision measurements of the Standard Model parameters and the number of the neutrino generations. Under his leadership, the AMS permanent magnet system was constructed in Beijing, and became the payload of the space shuttle Discovery 1998 as the first large magnet in Space. Since 2001, he was the project manager of the Beijing Electron Positron Collider Upgrade (BEPCII). BEPCII finished the construction on schedule within budget, and reached the design specification 2009. The luminosity of the BEPCII increased by a factor of more than 100 compared with the one before upgrade, and is a factor 14 more than the previous world record in the energy region. The Beijing Electron Positron Collider Upgrade (BEPCII) won the first prize of the National Science and Technology Progress Award in 2016.
