Description
The National Nuclear Data Center (NNDC) at Brookhaven National Laboratory (BNL) has developed and maintained NuDat, a web application where users can explore several databases containing nuclear structure, nuclear decay, and neutron-induced nuclear reaction information. NuDat is the primary web application used to query and visualize meticulously evaluated recommended values derived from all published experimental nuclear structure and decay data contained within the Evaluated Nuclear Structure Data File (ENSDF). NuDat was first developed over 15 years ago and now there are over 4 million queries to NuDat each year for research, education, and a wide range of applications. In order to provide an enhanced user experience, NuDat 3.0 is currently being developed and incorporating the latest computing technologies.
The modernized NuDat 3.0 is implemented using HTML Canvas to create a dynamic chart of nuclides. Users can seamlessly interact with over 3,300 nuclides with intuitive pan and zoom gestures. NuDat 3.0 is accompanied by interactive plots that are similarly controlled. NuDat 3.0 has a full range of features to support exploring the nuclear data contained within ENSDF. For example, the supplementary plots can be synced to automatically plot data displayed in the current view of the interactive chart of nuclides. The goal is to create responsive nuclear data visualizations to support user needs and uniquely visualize the vast amounts of data that ENSDF has to offer.
Beyond the interactive chart of nuclides, NuDat offers a full suite of web applications to search and visualize nuclear data. The Advanced Cross-Variable Plot provides users with an interface to create various plots by selecting axis variables from a multitude of observable properties. These plots have been modernized to generate feature rich and dynamic visualizations that are both highly interactive and customizable. NuDat 3.0 also provides fully interactive level and decay schemes for relevant nuclei. Users can intuitively navigate and customize these complex schemes to precisely view the desired nuclear data properties.
NuDat has considerably evolved since its inception. NuDat 3 will continue to improve based on feedback from the community with a focus on developing novel visualization tools to provide users with an intuitive interface to the nuclear data within ENSDF and ENDF. The ubiquitous demand for meticulously evaluated nuclear data emphasizes the need for modernizing NuDat using the latest computing technologies, in order to provide an enhanced user experience.
