Emission Ghost Imaging: reconstruction with data augmentation

February 1, 2024
Author(s)
Kevin J. Coakley, Heather H. Chen-Mayer, Bruce D. Ravel, Daniel Josell, Nikolai Klimov, Sarah Robinson, Daniel S. Hussey
Ghost Imaging enables 2D reconstruction of an object even though particles transmitted or emitted by the object of interest are detected with a single pixel detector without spatial resolution. This is possible because the incident beam is spatially

A portable triaxial cell for beamline imaging of rocks under triaxial state of stress

April 21, 2021
Author(s)
Amer Syed, Yukie Tanino, Jacob LaManna, David L. Jacobson, Daniel S. Hussey, Eli Baltic, Genoveva Burca
With recent developments in direct imaging techniques using x-ray and neutron imaging, there is an increasing need for an efficient design of a test setup to study mechanical and/or the transport behaviour of porous rocks. Bespoke design from commercial

Water retention curves are essential for understanding the hydrologic behavior of partially- saturated porous media and modeling flow transport processes within the vadose zone. In this paper we report direct measurements of the main drying and wetting

Cold Neutron Radiation Does Effects on a 6 LiF:ZnS(Ag) Neutron Detector with Wavelenght Shifting Fibers and SiPM Photodectector

Kevin NMN Pritchard, Daniel S. Hussey, A. Osovizky, Jeffrey B Ziegler, Louis Edward Binkley, Peter Tsai, Nancy Hadad, M. Jackson, C. Hurlbut, George M Baltic, Charles Majkrzak, Nicholas C. Maliszewskyj
A 6LiF:ZnS(Ag) based cold neutron detector with wavelength shifting (WLS) fibers and SiPM photodetector was developed at the NIST Center for Neutron Research for the CANDoR instrument (Chromatic Analysis Neutron Diffractometer or Reflectometer). To predict

Demonstration of focusing Wolter mirrors for neutron phase and magnetic imaging

April 21, 2021
Author(s)
Daniel S. Hussey, Han Wen, Huarui Wu, Thomas R. Gentile, Wangchun Chen, David L. Jacobson, Jacob LaManna, B. Khaykovich
Image-forming focusing mirrors were employed to demonstrate two different modalities of neutron imaging, phase imaging with a far-field interferometer, and magnetic-field imaging through the manipulation of the neutron beam polarization. For the phase

Demonstration of Small-Angle Neutron Scattering Measurements with a Nested Neutron-Focusing Supermirror Assembly

April 21, 2021
Author(s)
Huarui Wu, Zhiyuan Wang, Yao Zhang, Wenbo Mo, Pulin Bai, Kun Song, Zhong Zhang, Zhanshan Wang, Daniel S. Hussey, Yun Liu, Zhe Wang, Xuewu Wang
Neutron-focusing mirrors with both a nested structure and supermirror coatings enable a large collecting area, and consequently a large neutron current gain for mirror-based instruments. A nested neutron-focusing supermirror assembly has been fabricated

Design of a neutron microscope based on Wolter mirrors

April 21, 2021
Author(s)
Daniel S. Hussey, B. Khaykovich, Jeremy C. Cook, David L. Jacobson, Jacob LaManna, Kiranmayee Kilaru, Brian Ramsey, M. V. Gubarev
The predominate geometry for a neutron imaging experiment is that of a pinhole camera. This is primarily due to the difficulty in focusing neutrons due to the weak refractive index, which is also strongly chromatic. Proof of concept experiments

Effects of Cathode Corrosion on Through-Plane Water Transport in Proton Exchange Membrane Fuel Cells

April 21, 2021
Author(s)
Daniel S. Hussey, Joseph Fairweather, Dusan Spernjak, Adam Weber, David Harvey, Silvia Wessell, David L. Jacobson, Kateryna Artyushkova, Rangachary Mukundan, Rodney Borup
The corrosion of carbon in the electrode supports of proton-exchange-membrane fuel cells leads to electrode collapse, reduced active catalyst area, and increased surface hydrophilicity. While these effects have been linked to performance degradation over

Far-field interference of a neutron white beam and the applications to noninvasive phase-contrast imaging

April 21, 2021
Author(s)
Michael G. Huber, Daniel S. Hussey, Muhammad D. Arif, David L. Jacobson, Jacob LaManna, Wakana Ueno, Han Wen, Dmitry Pushin, Dusan Sarenac, David Cory, Houxun Miao, Takenao Shinohara, Joseph Parker
The phenomenon of interference plays a crucial role in the field of precision measurement science. Waveparticle duality has expanded the well-known interference effects of electromagnetic waves to massive particles. The majority of the wave-particle
