Abstract
The use of NERI to simultaneously map multiple elements throughout the entire volume of a sample in three-dimensions has been demonstrated. This was accomplished by imaging uranium- and gadolinium-containing oxide spheres produced using the internal gelation sol-gel method. The work presented here is an important step towards the frequent utilization of the developed and demonstrated NERI capabilities at the SNS to study a variety of high-Z materials, such as those used in the nuclear industry.

Funding
This material is based upon research sponsored by the Laboratory Directed Research and Development Program of Oak Ridge National Laboratory, managed by UT-Battelle LLC for the US Department of Energy. This research used resources at the Spallation Neutron Source, a DOE Office of Science User Facility operated by Oak Ridge National Laboratory. The spectra obtained from NERI measurements of the uranium/gadolinium oxide spheres are given in Fig. 1. The peaks correlating to uranium and gadolinium resonances are indexed with diamonds (♦) and squares (■), respectively. The radiographs correlating to each of the indexed peaks were summed together to produce element-specific radiographs, such as the one shown in Fig. 2. Element-specific tomographs were then produced from the radiographs (36 for gadolinium and 36 for uranium) by the Filtered Back Notice: This manuscript has been authored by UT-Battelle, LLC, under contract DE-AC05-00OR22725 with the US Department of Energy (DOE).
