Title: Neutron Scattering Instrumentation Research and Development for High Spatial and Temporal Resolution Imaging at Oak Ridge National Laboratory

Abstract

Neutron scattering facilities like those available at ORNL are enabling the discovery and development of advanced materials include those to be used for next generation energy storage systems. In spite of all the success that neutron imaging has enjoyed in recent years, even higher-impact research is limited by the current temporal and spatial resolution of neutron detection devices. In particular, the spatial resolution of all neutron imaging methods in use and under development is fundamentally limited by the variance introduced by the charged particles emitted from neutron absorption. Thus, we are investigating, designing and demonstrating an array of ~1 micron-sized glass scintillating fibers arranged via photonics-crystal-fiber patterning techniques-- with particle tracking (a must) so that position resolution can be finer than than that allowed by the charged particle ranges. The processes, knowledge and algorithms developed will allow for spatially (1 micron) and time resolved (<100 ns), high throughput neutron transmission imaging in large areas at reasonable costs.
