报告摘要：

National Synchrotron Light Source II (NSLS-II) is a highly optimized synchrotron facility being constructed on Long Island, New York. When completed in 2014, it will offer cutting-edge capabilities with high spectral brightness and will enable a wide-range of scientific applications.  In this talk I will provide an overview of the NSLS-II facility, discuss the first set of beamlines at NSLS-II, and describe the advanced R&D programs related to NSLS-II beamlines.  I will then focus the discussion on the science programs envisioned at the NSLS-II particularly in the areas of energy and health, and the overall strategic directions that Photon Sciences is pursuing at Brookhaven National Laboratory.

报告人介绍：

Dr. Shen is the Director of the Photon Division of Photon Science Directorate, Director of Experimental Facilities at National Synchrotron Light Source II (NSLS-II), and a Senior Physicist at Brookhaven National Laboratory.  He also holds Adjunct Professorships in Materials Science & Engineering at Northwestern University and in Physics at Purdue University.  Before joining Brookhaven in 2008, Dr. Shen was Head of the X-ray Microscopy and Imaging Group at the X-ray Science Division at the Advanced Photon Source in Argonne National Laboratory for three and a half years. Prior to Argonne, he was a Senior Staff Scientist and Head of the X-ray Optics Group at Cornell High Energy Synchrotron Source, and an Adjunct Associate Professor in Materials Science & Engineering at Cornell University for more than seventeen years.  He has held visiting scholarship and professorships at the European Synchrotron Radiation Facility in France and at the Chinese Academy of Sciences in China. 

Dr. Shen is the recipient of numerous professional awards during his career. He has been elected a Fellow of the American Physical Society for important contributions to x-ray physics, particularly in the field of x-ray diffraction in relationship to the phase problem in proteins. He has received the Distinguished Alumnus Award from the School of Science at Purdue University, the S.S. Sidhu Award on outstanding contributions in the area of x-ray diffraction and scattering from the Pittsburgh Diffraction Society, and the Lark-Horowitz Prize in Physics from Purdue University. Dr. Shen was a Scientific Member and Developer during the early stages of the Synchrotron Radiation Instrumentation Collaborative Access Team at the APS, with the particular emphasis on x-ray physics of materials and polarization studies. Dr. Shen has published more than one hundred scientific journal articles and book chapters, and has given more than one hundred invited lectures and ninety-plus other presentations in scientific meetings, conferences, and seminars. 

As the Division Director, Dr. Shen leads the development of all aspects of the Experimental Facilities at NSLS-II, which is a 3^rd generation synchrotron facility being constructed at Brookhaven National Laboratory, and is responsible for photon beamline operations and science programs at the existing National Synchrotron Light Source (NSLS). The Photon Division currently consists of over 90 full-time staff scientists and engineers, and is responsible for the development, implementation, and operation of scientific experimental programs at NSLS-II and NSLS including interactions with the broad scientific user community. In addition to managing the experimental programs, Dr. Shen’s current research interest focuses on high-resolution x-ray microscopic studies of nanoparticles, heterogeneous noncrystalline specimens, and biological cells and assemblies using both lens-based x-ray microscopes and lensless imaging methods based on coherent diffraction and phase retrieval.
