IMR-MIP DANSE - Distributed Data Analysis for Neutron Scattering Experiments - CNST

这是对散裂中子源的分布式中子散射实验数据分析(DANSE)的建设的奖励。它得到了DMR的材料研究仪器-中等规模仪器项目计划、数学和物理科学局的多学科活动办公室以及DMR的化学部和工程部的化学运输部的支持。DANSE项目的目标是建立一个软件系统，该系统1)使新的、更复杂的科学能够通过中子散射实验进行，2)使所有科学家更容易分析数据，3)提供一个可在未来维护的强大的软件基础设施。DANSE计划是由散裂中子源(http://www.sns.gov))的发展推动的。2006年，SNS将开始生产用于探测材料、分子和凝聚态物质的强流中子束。在SNS进行的中子散射实验将产生关于原子和自旋在材料、分子和凝聚态中的位置和运动的前所未有的详细数据。使用SNS仪器获得的原始实验数据并不容易解释，需要新的软件将数据转换为有用的形式。利用过去十年在计算材料科学方面取得的几项重大进展，丹斯项目将提供新的数据简化和解释能力，而不是目前可用的能力。DANSE项目包括一个以加州理工大学为中心的中心资源活动，以及位于不同机构的5个组成部分：由密歇根州立大学的Simon J.L.Billinger领导的衍射，由爱荷华州立大学的Ersan Ustundag领导的工程衍射。，由大学的保罗·基恩泽尔领导的反射术。由马里兰州大学的保罗·巴特勒领导的小角度散射。以及由洛斯阿拉莫斯的Frans Trouw和B.Fultz领导的非弹性散射。有关该项目的信息可在http://wiki.cacr.caltech.edu/danse/index.php/Main_PageThe上获得，该项目正在帮助组织美国的中子散射科学界，并引起了全世界的兴趣。Danse是基于网格的计算的自然应用程序，Danse框架的分层设计是为了迁移到TeraGrid或类似的未来网络基础设施。DANSE框架可用于其他科学领域的数据分析。已计划与爱荷华州立大学的教育专业人员合作开展外展工作。

This is an award for the construction of a Distributed Data Analysis for Neutron Scattering Experiments (DANSE) at the Spallation Neutron Source. It is supported by the Instrumentation for Materials Research- Mid Scale Instrumentation project program in DMR, the Office of Multidisciplinary Activity in the Mathematical and Physical Sciences Directorate, as well as the Chemistry division in DMR and the Chemical Transport Division in Engineering Directorate. The goals of the DANSE project are to build a software system that 1) enables new and more sophisticated science to be performed with neutron scattering experiments, 2) makes the analysis of data easier for all scientists, and 3) provides a robust software infrastructure that can be maintained in the future. The DANSE project was prompted by the development of the Spallation Neutron Source (http://www.sns.gov) (SNS). In 2006 the SNS will start to produce intense beams of neutrons to be used as probes of materials, molecules, and condensed matter. Neutron scattering experiments performed at the SNS will produce data of unprecedented detail on the positions and motions of atoms and spins in materials, molecules, and condensed matter. The raw experimental data acquired using the SNS instruments are not simple to interpret, and new software is required to transform the data into useful forms. Using several major advances in computational materials science that have occurred over the past decade the DANSE project will provide new data reduction and interpretation capabilities beyond what are available today. The DANSE project includes a central resource activity centered at Caltech, and 5 components based at different institutions: diffraction led by Simon J.L. Billinge of Michigan State Univ., engineering diffraction led by Ersan Ustundag of Iowa State Univ. , reflectometry led by Paul Kienzle of the Univ. of Maryland, small-angle scattering led by Paul Butler of the Univ. of Tennessee, and inelastic scattering led by Frans Trouw of Los Alamos with B. Fultz. Information about the project is available at http://wiki.cacr.caltech.edu/danse/index.php/Main_PageThe project is helping to organize the neutron scattering science community in the U.S., and has generated worldwide interest. DANSE is a natural application for grid-based computing, and the layered design of the DANSE framework was planned for migration to the TeraGrid, or a similar future cyber infrastructure. The DANSE framework could be adapted for data analysis in other fields of science. An outreach effort has been planned as collaboration with education professionals at Iowa State University.
