Single-exposure elemental differentiation and texture-sensitive phase-retrieval imaging with a neutron counting micro-channel plate detector
Benedicta D. Arhatari, David M. Paganin, Henry Kirkwood +9
Micro-channel plate (MCP) detectors, when used at pulsed-neutron-source instruments, offer the possibility of high spatial resolution and high contrast imaging with pixel-level spe…
Needs, trends, and advances in scintillators for radiographic imaging and tomography
Zhehui Wang, Christophe Dujardin, Matthew S. Freeman +17
Scintillators are important materials for radiographic imaging and tomography (RadIT), when ionizing radiations are used to reveal internal structures of materials. Since its inven…
Antiferromagnetic real-space configuration probed by dichroism in scattered x-ray beams with orbital angular momentum
Margaret R. McCarter, Ahmad I. U. Saleheen, Arnab Singh +8
X-ray beams with orbital angular momentum (OAM) are a promising tool for x-ray characterization techniques. Beams with OAM have a helicity--an azimuthally varying phase--which lead…
A multimodal operando neutron study of the phase evolution in a graphite electrode
Monica-Elisabeta Lăcătuşu, Luise Theil Kuhn, Rune E. Johnsen +8
Obtaining a complete picture of local processes still poses a significant challenge in battery research. Here we demonstrate an in-situ combination of multimodal neutron imaging wi…
Switchable X-ray Orbital Angular Momentum from an Artificial Spin Ice
Justin Woods, Xiaoqian M Chen, Rajesh V. Chopdekar +12
Artificial spin ices (ASI) have been widely investigated as magnetic metamaterials with exotic properties governed by their geometries. In parallel, interest in X-ray photon orbita…
Synchrotron Microtomography and Neutron Radiography Characterization of the Microstruture and Water Absorption of Concrete from Pompeii
Ke Xu, Anton S. Tremsin, Jiaqi Li +9
There is renewed interest in using advanced techniques to characterize ancient Roman concrete. In the present work, samples were drilled from the "Hospitium" in Pompeii and were an…
Bayesian Non-parametric Bragg-edge Fitting for Neutron Transmission Strain Imaging
Johannes Hendriks, Nicholas O'Dell, Adrian Wills +3
Energy resolved neutron transmission techniques can provide high-resolution images of strain within polycrystalline samples allowing the study of residual strain and stress in engi…
Disparate exciton-phonon couplings for zone center and boundary phonons in solid-state graphite
Xuefei Feng, Shawn Sallis, Yu-Cheng Shao +8
The exciton-phonon coupling in highly oriented pyrolytic graphite is studied using resonant inelastic X-ray scattering (RIXS) spectroscopy. With ~ 70 meV energy resolution, multipl…
Tomographic Reconstruction of Triaxial Strain Fields from Bragg-Edge Neutron Imaging
J. N. Hendriks, A. W. T. Gregg, R. R. Jackson +6
This paper presents a proof-of-concept demonstration of triaxial strain tomography from Bragg-edge neutron imaging within a three-dimensional sample. Bragg-edge neutron transmissio…
Tomographic Reconstruction of Two-Dimensional Residual Strain Fields from Bragg-Edge Neutron Imaging
Alexander Gregg, Johannes Hendriks, Christopher Wensrich +7
Bragg-edge strain imaging from energy-resolved neutron transmission measurements poses an interesting tomography problem. The solution to this problem will allow the reconstruction…
Bragg-Edge Elastic Strain Tomography for in situ Systems from Energy-Resolved Neutron Transmission Imaging
J. N. Hendriks, A. W. T. Gregg, C. M. Wensrich +6
Technological developments in high resolution time-of-flight neutron detectors have raised the prospect of tomographic reconstruction of elastic strain fields from Bragg-edge strai…
Time-of-Flight Three Dimensional Neutron Diffraction in Transmission Mode for Mapping Crystal Grain Structures
Alberto Cereser, Markus Strobl, Stephen Hall +17
The physical properties of polycrystalline materials depend on their microstructure, which is the nano-to-centimeter-scale arrangement of phases and defects in their interior. Such…
Three Dimensional Polarimetric Neutron Tomography of Magnetic Fields
