High Energy Nuclear Database: A Testbed for Nuclear Data Information Technology

摘要

We describe the development of an on-line high-energy heavy-ion experimental database. When completed, the database will be searchable and cross-indexed with relevant publications, including published detector descriptions. While this effort is relatively new, it will eventually contain all published data from older heavy-ion programs as well as published data from current and future facilities. These data include all measured observables in proton-proton, proton-nucleus and nucleus-nucleus collisions. Once in general use, this database will have tremendous scientific payoff as it makes systematic studies easier and allows simpler benchmarking of theoretical models for a broad range of experiments. Furthermore, there is a growing need for compilations of high-energy nuclear data for applications including stockpile stewardship, technology development for inertial confinement fusion, target and source development for upcoming facilities such as the International Linear Collider and homeland security. This database is part of a larger proposal that includes the production of periodic data evaluations and topical reviews. These reviews would provide an alternative and impartial mechanism to resolve discrepancies between published data from rival experiments and between theory and experiment. Since this database will be a community resource, it requires the high-energy nuclear physics communitys financial and manpower support. This project serves as a testbed for the further development of an object-oriented nuclear data format and database system. By using off-theshelf software tools and techniques, the system is simple, robust, and extensible. Eventually we envision a Grand Unified Nuclear Format encapsulating data types used in the ENSDF, ENDF/B, EXFOR, NSR and other formats, including processed data formats.
