DAPHNE4NFDI - DAta from PHoton and Neutron Experiments for NFDI

光子和中子科学社区包括来自广泛科学学科的用户，他们面临着对高水平，快速数据分析的共同需求和实施研究数据管理的挑战。科学用户社区由KFS和KFN委员会代表，他们已经合作多年，并在这里聚集在一起，以应对实验数字化转型带来的共同挑战。DAPHNE联盟为广泛的使用光子和中子技术的用户社区提供服务，包括德国的5000多名科学家。该社区每年在中心设施进行数千次个人用户实验，涉及许多学科，使用一系列技术和各种仪器。根据实验配置的不同，单个实验每周可以产生数百万个文件，在某些情况下可以产生超过1 PB的数据。此外，由于放射源本身亮度的增加（x射线自由电子激光器、高亮度储存环和新的中子设施）以及现代探测器的尺寸和速度的迅速增加，目前在记录的数据量和相应的数据率方面都发生了根本性的变化。DAPHNE将代表关键科学应用领域的用户与光子和中子科学的大型研究设施聚集在一起，以促进社区数据管理的状态。独特的是，DAPHNE直接与用户社区合作，开发用户驱动的数据解决方案，以推进科学实验。总的来说，我们将通过DAPHNE为更广泛的光子和中子社区提供以下有形基础设施：1。通过与数据收集相链接的用户驱动的在线日志支持的一致工作流改进元数据捕获，从而能够捕获比目前可能的更丰富的实验信息; 2.建立一个处理过的数据、新的参考数据库和已发表结果的分析代码的社区储存库，并在可能的情况下与原始数据源链接，以可持续地改善对研究数据的访问，并使数据和软件能够在社区内重复使用;在设施计算基础设施上开发、策划和部署用户开发的分析软件，以便普通用户可以受益于并重复领先的高级用户组通过通用数据分析门户进行的分析。此外，它将对德国参与的国际设施产生强烈的积极副作用，如ESRF（法国格勒诺布尔）和ESS（瑞典隆德）

The photon and neutron science community encompasses users from a broad range of scientific disciplines facing a common need for high- level, rapid data analysis and the challenge of implementing research data management. The communities of science users are represented by the KFS and KFN committees, which have worked together for many years and are coming together here to meet common challenges imposed by the digital transformation of experiments. The DAPHNE consortium serves the broad community of users employing a wide range of photon and neutron techniques, comprising more than 5000 scientists throughout Germany. The community performs thousands of individual user experiments at central facilities every year, across many disciplines and using a range of techniques and a diverse instrumentation. Individual experiments can produce millions of files and in some cases over 1 PB data per week, depending on the experimental configuration. Moreover, the community is currently witnessing a fundamental change in both the amount of data recorded and the corresponding data rates triggered by the increase in the brightness of the sources themselves (x-ray free-electron lasers, high-brightness storage rings and new neutron facilities) and by the rapid increase in the size and speed of modern detectors. DAPHNE brings together users representing key scientific application domains with the large-scale research facilities in photon and neutron science in order to advance the state of data management in the community. Uniquely, DAPHNE engages directly with the user community to develop user-driven data solutions to advance science experiments. Broadly, we will provide the following tangible infrastructure through DAPHNE for the wider photon and neutron community: 1. Improve metadata capture through consistent workflows supported by user-driven online logbooks linked to the data collection, thus enabling a richer capture of information about the experiments than is currently possible; 2. Establish a community repository of processed data, new reference data bases and analysis code for published results, linked where possible to raw data sources, to sustainably improve access to research data and enable data and software re-use within the community; and 3. Develop, curate and deploy user-developed analysis software on facility computing infrastructure so that ordinary users can benefit from and repeat the analysis performed by leading power user groups through common data analysis portals. Furthermore, it will have strong positive side- effects for international facilities with German participation, such as the ESRF (Grenoble, France) and the ESS (Lund, Sweden)
