主講人簡介：

陳和生，中國科學院院士、粒子物理學家。1970年畢業(yè)于北京大學原子核物理專業(yè)。1984年5月獲得美國麻省理工學院博士學位。曾任高能所所長（1998-2011）、中國高能物理學會理事長、中國物理學會副理事長、亞洲未來加速器委員會主席等職?，F(xiàn)任北京正負電子對撞機國家實驗室主任、國家“十二五”重點工程中國散裂中子源工程指揮部總指揮和工程經理部經理。

陳和生院士長期從事粒子物理實驗研究。1979至1986年在德國漢堡DESY參加丁肇中教授領導的Mark-J實驗，為膠子物理研究和精確檢驗標準模型作出重要貢獻。1983年起參加歐洲核子研究中心L3實驗物理方案制定和探測器設計，負責強子量能器設計、模擬和重建程序工作，主持tau物理分析組工作，對精確檢驗標準模型、測定電弱參數(shù)和中微子代數(shù)等作出重要貢獻。1995至1997年主持阿爾法磁譜儀（AMS）大型永磁體系統(tǒng)的研制，在北京成功研制了人類送入太空的第一個大型磁體，該磁體于1998年搭載航天飛機進行了首次飛行，并于2011年送到國際空間站長期運行，該項目獲2000年國家科技進步二等獎（第一獲獎人）。提出BEPC發(fā)展的科學目標和方案，成功主持北京正負電子對撞機重大改造工程（BEPCII）。其主要性能比改造前提高100倍，為此前世界紀錄的14倍，現(xiàn)在運行1年獲得數(shù)據相當于改造前的100年?！氨本┱撾娮訉ψ矙C重大改造工程”獲2016年國家科學技術進步一等獎。2017年5月獲得首屆全國創(chuàng)新爭先獎章。

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.
