Virtual Instrumentation Experiment Optimization for High-Throughput Scientific Analysis

Neutron scientists using large-scale neutron facilities, such as the Spallation Neutron Source (SNS) located at Oak Ridge National Laboratory, want to be prepared when they arrive at the facility, but virtual experiment capabilities are not sufficient for proper planning. This project will extend the Orbiter Virtual File System, developed in collaboration with the SNS, to provide virtual instrumentation-experiment optimization capabil­ities to neutron scientists. The technology not only will allow the neutron scientist to perform extensive pre-experiment virtual simulations but also will provide a high Quality of Service, yielding more efficient use of the facility. In Phase I, the Orbiter Virtual File System Service Oriented Architecture was implemented, providing a wealth of neutron facility information, experiment data file access and search capabilities, and authentication and authorization management. In Phase II, a robust and reliable service infrastructure will be developed to increase the effective system performance. Commercial Applications and other Benefits as described by the awardee: The successful implementation of the proposed infrastructure and prototype should directly benefit U.S. and international neutron facilities. Improved simulations of neutron experiments using virtual instrumentation-experiment optimization should contribute to multiple applications in energy research, electronics, material science, manufacturing, and medical research
