1. Advancement of Light-Element Neutron Depth Profiling at the University of Texas
Published: 4/1/2008
Authors: S M Whitney, Robert G Downing, S Biegalski, D S O'Kelly
Abstract: The University of Texas (UT) at Austin has collaborated with the National Institute of Standards and Technology for comparisons of concentration versus depth profiles of samples containing 10B. Technology sharing from NIST has allowed UT to avoid ma ...

7. Cold-Neutron Depth Profiling as a Research Tool for the Study of Surface Oxides on Metals
Published: 10/7/2010
Authors: Robert G Downing, Z Tun, J.J. Noel, Th Bohdanowicz, L.R. Cao
Abstract: A recent experiment at NIST has demonstrated that neutron depth profiling (NDP) based on (n,α) reaction could be developed into a tool routinely used for the study of passive oxides on metals. Whereas most metals are not (n,α) active, oxide ...

8. Combinatorial Study of Thin Film Metal Hydride by Prompt Gamma Activation Analysis
Published: 6/19/2009
Authors: Raymond Cao, Jason Hattrick-Simpers, Richard Bindel, Bryan E. Tomlin, Rolf Louis Zeisler, Rick L Paul, Leonid A Bendersky, Robert G Downing
Abstract: Cold neutron prompt gamma activation analysis (PGAA) was used to determine the amount of hydrogen in thin film Mg hydrides with varying hydrogenation times. The results suggest that the hydrogenation in the Mg thin films remains unsaturated even afte ...

9. Design of a Prototype Microchannel Plate Detector with Cooled Amorphous Silicon Array Readout for Neutron Radiography
Published: 11/1/2005
Authors: Robert G Downing, R. M. Ambrosi, G. W. Fraser, R. A. Street, J.I. W. Watterson, R. C. Lanza, J. Dowson, F. F. Abbey, W B Feller, Gregory White, T. Stevenson

10. Development and Applications of Time-of-Flight Neutron Depth Profiling (TOF-NDP)
Published: 6/1/2008
Authors: S M Cetiner, K Unlu, Robert G Downing
Abstract: Neutron depth profiling (NDP) is a surface analysis technique based on the illumination of samples with thermal or sub-thermal neutrons, and subsequent release of charged particles. Emitted particles rapidly lose kinetic energy primarily through int ...
