"The VENUS project: novel neutron imaging capabilities at the Spallation Neutron Source"

Speaker: Dr. Hassina Bilheux
ORNL Neutron Sciences Directorate
Oak Ridge National Laboratory-Oak Ridge, TN

For decades, neutron imaging has flourished at steady-state facilities (i.e. reactors) that offer intense beams of polychromatic neutrons. At these facilities, scientific applications spawn from energy materials, additive manufacturing, engineering, to plant physiology, biology, archeology, etc. Recently, advanced techniques such as polarized neutron imaging and grating interferometry have been implemented at these neutron user facilities. More recently, and with the development of time-of-flight (TOF) imaging detectors, neutron wavelength-dependent imaging techniques (Bragg-edge and resonance imaging) have thrived at spallation neutron sources and have yielded the construction of state-of-the-art neutron imaging beamlines such as RADEN at J-PARC, Japan, or IMAT in the UK. Spalled neutrons offer novel imaging contrast mechanisms not easily attainable at reactors. Oak Ridge National Laboratory is building the Spallation Neutron Source VENUS neutron imaging beamline, that is optimized for TOF imaging capabilities. This presentation will provide an overview of the capabilities at VENUS, along with examples of science areas this instrument will excel at, particularly in the field of materials sciences (additive manufacturing, nuclear materials, etc.).

Dr. Bilheux obtained her Ph.D. in Physics from the University of Versailles-Saint-Quentin-en-Yvelines, France, in 2003. Her Ph.D. research was performed at the Physics Division of the Oak Ridge National Laboratory (ORNL) on electron cyclotron resonance ion sources. After a post-doctoral research appointment at the ORNL Physics Division, Dr. Bilheux joined the ORNL Neutron Sciences Directorate in 2005. She is responsible for neutron radiography and computed tomography capabilities at both the Spallation Neutron Source and the High Flux Isotope Reactor. Her expertise includes neutron technology development and image processing and analysis. Dr. Bilheux is interested in applying advanced imaging techniques in the fields of materials science (such as energy materials and additive manufacturing), geosciences and biological applications at the Spallation Neutron Source VENUS imaging beamline (to be operational in 2022).

This research was sponsored by the Scientific User Facilities Division, Office of Basic Energy Sciences, U.S. DOE. This research used resources at the Spallation Neutron Source and the High Flux Isotope Reactor, U.S. Department of Energy (DOE) Office of Science User Facilities operated by the Oak Ridge National Laboratory.
