主讲人简介：

陈和生，中国科学院院士、粒子物理学家。1970年毕业于北京大学原子核物理专业。1984年5月获得美国麻省理工学院博士学位。曾任高能所所长（1998-2011）、中国高能物理学会理事长、中国物理学会副理事长、亚洲未来加速器委员会主席等职。现任北京正负电子对撞机国家实验室主任、国家“十二五”重点工程中国散裂中子源工程指挥部总指挥和工程经理部经理。

陈和生院士长期从事粒子物理实验研究。1979至1986年在德国汉堡DESY参加丁肇中教授领导的Mark-J实验，为胶子物理研究和精确检验标准模型作出重要贡献。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作出重要贡献。1995至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2000年国家科技进步二等奖（第一获奖人）。提出BEPC发展的科学目标和方案，成功主持北京正负电子对撞机重大改造工程（BEPCII）。其主要性能比改造前提高100倍，为此前世界纪录的14倍，现在运行1年获得数据相当于改造前的100年。“北京正负电子对撞机重大改造工程”获2016年国家科学技术进步一等奖。2017年5月获得首届全国创新争先奖章。

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.
