The Spallation Neutron Source (the "SNS"), under construction in Oak Ridge, Tennessee with a budget of $B1.411, is the world's largest science construction project. In 2006 it will start to produce intense beams of neutrons to be used as probes of materials. The instruments that control these beams, and detect the neutrons scattered from specimens, are state-of-the-art. 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. Under the IMR-MIP program at the NSF, a conceptual engineering design effort is being supported to build software for the analysis of data from the SNS and other neutron facilities in a system called DANSE - distributed data analysis for neutron scattering experiments. The DANSE project includes a central resources activity, and subprojects in the different subfields of neutron scattering science at different institutions around the U.S. The lead institution is the California Institute of Technology. The scientific subprojects are led by faculty at Michigan State Univ. (diffraction), at Iowa State Univ. (engineering diffraction), the University of Maryland (reflectometry), the University of Tennessee (small-angle scattering), and Los Alamos, and Caltech.DANSE uses a new software architecture based on the data flow paradigm. Analysis is performed with reusable software components that can be connected across a network using standardized data streams. Components are integrated into a coherent interpretive framework using the open source language Python so that custom analysis procedures can be constructed easily at runtime. The architecture enables high performance computing on distributed resources and opens access to the future cyber infrastructure of grid-based computing. DANSE provides an unprecedented opportunity to merge data analysis, theory, and simulation into a uniform computing environment. 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 Spallation Neutron Source (the "SNS"), under construction in Oak Ridge, Tennessee with a budget of $ 1,411,000,000, is the world's largest science construction project. In 2006 it will start to produce intense beams of neutrons to be used as probes of materials. The instruments that control these beams, and detect the neutrons scattered from the specimens under study, are state-of-the-art. Neutron scattering experiments performed at the SNS will produce data of unprecedented detail on the positions and motions of atoms in materials. The raw experimental data acquired with these instruments are not simple to interpret, and new software is required to transform the data into useful forms. Beyond such data reductions that are available today, there is an opportunity to interpret data using several major advances in computational materials science that have occurred over the past decade. Under the IMR-MIP program at the NSF, a conceptual engineering design effort is being supported to build a software system called DANSE - distributed data analysis for neutron scattering experiments. The DANSE project includes two parts. The first is a software engineering effort to build a framework that permits the interoperability of modular software components. The second is an effort by scientistsat different institutions around the U.S. to develop the software components needed for data analysis for the different subfields of neutron scattering research. The lead institution is the California Institute of Technology. The scientific subprojects are led by scientists at Michigan State University, Iowa State University, the University of Maryland, and University of Tennessee.

散裂中子源（简称“SNS”）正在田纳西州橡树岭建设，预算为 1.411 美元，是世界上最大的科学建设项目。 2006 年它将开始产生强中子束，用作材料探测器。控制这些光束并检测样本散射中子的仪器是最先进的。在 SNS 进行的中子散射实验将产生有关材料、分子和凝聚态物质中原子和自旋的位置和运动的前所未有的详细数据。在 NSF 的 IMR-MIP 计划下，正在支持一项概念工程设计工作，以构建用于分析来自 SNS 和其他中子设施的数据的软件，该系统称为 DANSE（中子散射实验的分布式数据分析）。 DANSE 项目包括一项中央资源活动以及美国各地不同机构的中子散射科学不同子领域的子项目。牵头机构是加州理工学院。科学子项目由密歇根州立大学的教师领导。 （衍射），爱荷华州立大学。 （工程衍射）、马里兰大学（反射测量）、田纳西大学（小角度散射）、洛斯阿拉莫斯大学和加州理工学院。DANSE 使用基于数据流范例的新软件架构。分析是通过可重复使用的软件组件执行的，这些组件可以使用标准化数据流通过网络连接。使用开源语言Python将组件集成到一个连贯的解释框架中，以便可以在运行时轻松构建自定义分析过程。该架构支持对分布式资源进行高性能计算，并开放对基于网格计算的未来网络基础设施的访问。 DANSE 提供了前所未有的机会，将数据分析、理论和模拟合并到统一的计算环境中。 DANSE 项目的目标是构建一个软件系统，1) 能够通过中子散射实验进行新的、更复杂的科学，2) 使所有科学家更容易进行数据分析，3) 提供一个可以在未来维护的强大软件基础设施。散裂中子源（“SNS”）正在田纳西州橡树岭建造，预算为 1,411,000,000 美元，是世界上最大的中子源科学 建设项目。 2006 年它将开始产生强中子束，用作材料探测器。控制这些光束并检测从所研究的样本中散射的中子的仪器是最先进的。在 SNS 上进行的中子散射实验将产生有关材料中原子的位置和运动的前所未有的详细数据。使用这些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。除了当今可用的数据缩减之外，还有机会利用过去十年中计算材料科学的几项重大进展来解释数据。在 NSF 的 IMR-MIP 计划下，正在支持一项概念工程设计工作，以构建一个名为 DANSE 的软件系统 - 用于中子散射实验的分布式数据分析。 DANSE 项目包括两部分。第一个是软件工程努力构建一个允许模块化软件组件互操作的框架。第二个是美国各地不同机构的科学家努力开发中子散射研究不同子领域的数据分析所需的软件组件。牵头机构是加州理工学院。这些科学子项目由密歇根州立大学、爱荷华州立大学、马里兰大学和田纳西大学的科学家领导。 DANSE 项目的目标是构建一个软件系统，该系统 1) 能够通过中子散射实验进行新的、更复杂的科学，2) 使所有科学家更容易进行数据分析，3) 提供一个可以在未来维护的强大软件基础设施。
