研究方向：粒子物理实验研究
主要工作和成果：
1979-1984年参加Mark-J实验，为胶子物理研究和精确检验标准模型做出重要贡献。1983年起参加欧洲核子研究中心L3实验物理方案制定和探测器设计，负责强子量能器设计、模拟和重建程序工作，主持tau物理分析组工作，对精确检验标准模型、测定电弱参数和中微子代数等做出重要贡献。1995-1997年主持阿尔法磁谱仪（AMS）大型永磁体系统的研制，在北京成功研制了人类送入太空的第一个大型磁体。该磁体于1998年搭载航天飞机进行了首次飞行，并于2011年送到国际空间站长期运行。该项目获国家科技进步二等奖。提出BEPC发展的科学目标和方案，2004-2008担任北京正负电子对撞机重大改造工程（BEPCII）经理，按计划完成工程建设，达到设计指标。该项目获得中国科学院杰出科技成果奖。
Hesheng Chen, born in 1946, obtained Ph.D of Physics from Massachusetts Institute of Technology in 1984.
He is an Academician of Chinese Academy of Sciences. He was the director of Institute of High Energy
Physics from 1998 to 2011. He is currently the Director of BEPC National Laboratory of IHEP and Project
Manager of the China Spallation Neutron Source.
Areas of Research: experimental particle physics
Achievement and Experience: Achievement and Experience:
He worked at Mark-J Experiment of DESY 1979-1984 and made important contributions to the discovery of
three jet event and the gluon physics study, as well as the precision tests of the electroweak theory. Since
1982, he worked at the L3 experiment at CERN for its physics proposal and detector design, Monte Carlo
simulation and Tau physics, and made important contributions to the precision measurements of the
Standard Model parameters and the determination of the number of the neutrino generations. Under his
leadership, the AMS permanent magnet system was designed，constructed and space qualified in Beijing,
and became the payload of the space shuttle Discovery in 1998 as the first large magnet in Space. The
magnet was sent to the ISS May 2011 for long term running. He proposed the Beijing Electron Positron
Collider Upgrade (BEPCII). Since 2001 he was the project manager of BEPCII, and successfully led the
design, construction and commissioning of BEPCII. The project was finished on schedule and within the
budget, and reached the upgrade design specifications in 2009. The luminosity of the BEPCII has been
increased by a factor of 70 compared with the one before the upgrade.
