> Title: 3D+ X-ray & Neutron Imaging in Materials Science for Energy: Hydrogen Storage and Batteries
>  
> Abstract: Neutron imaging is an emerging field with new-found applications for energy applications.  Compared to X-ray imaging, neutron fluxes are much lower, thus speed and spatial resolution cannot compete with X-ray imaging.  However, neutron-matter interactions, especially with crystalline materials, offer unique contrast mechanisms.  We have shown that neutron imaging is sensitive to the lithium-graphite structures of charged lithium-ion polymer batteries, even when imaging an intact, commercial battery. Processing raw neutron images into clean 3D volumes is challenging.  First, the "sit still" requirement is violated when imaging a dynamic system; this problem is partially alleviated with a Greek golden ratio based angle order.  Second, the inverse Radon transform requires [0,1] neutron-matter interactions, a poor assumption for thicker samples.  Third, the large data volumes are challenging to reduce to a single scalar description of the complex sample.  Butler is a co-PI on an instrument development team seeking a $20M neutron imaging beamline at the ORNL Spallation Neutron Source, thus solutions to these problems are welcomed
