Journal of radioanalytical and nuclear chemistry : an international journal dealing with all aspects and applications of nuclear chemistry
In the course of the Fukushima nuclear accident, radionuclides were released in various forms, including so-called radiocesium-bearing microparticles (CsMP). So far, four types of CsMP were described: Type A is smaller in size ( 100 μm). In this wor

Characterization of extreme ultraviolet laser ablation mass spectrometry for actinide trace analysis and nanoscale isotopic imaging
Autor: Andrew M. Duffin, David Willingham, Jorge J. Rocca, Gregory C. Eiden, W. Chao, Ilya Kuznetsov, Benjamin E. Naes, Zihua Zhu, Tyler Green, Carmen S. Menoni
Publikováno v: Journal of Analytical Atomic Spectrometry. 32:1092-1100
We demonstrate a new technique for trace analysis that has nanometer scale resolution imaging capability: Extreme Ultraviolet Time-of-Flight Laser Ablation Mass Spectrometry (EUV TOF). We describe the characterization of this technique and discuss it

Fully convolutional neural network for removing background in noisy images of uranium bearing particles
Autor: Lamar Butler, Benjamin E. Naes, Andrea L. Howard, Jay G. Tarolli, Keeyahna Foster, David Willingham, Caleb M. Gumbs
Publikováno v: The Analyst. 142:1499-1511
A fully convolutional neural network (FCN) was developed to supersede automatic or manual thresholding algorithms used for tabulating SIMS particle search data. The FCN was designed to perform a binary classification of pixels in each image belonging

High resolution isotopic analysis of U-bearing particles via fusion of SIMS and EDS images
Autor: David Willingham, Benjamin J. Garcia, Benjamin E. Naes, Ashley E. Fischer, Jay G. Tarolli
Publikováno v: Journal of Analytical Atomic Spectrometry. 31:1472-1479
Image fusion of secondary ion mass spectrometry (SIMS) images and X-ray elemental maps from energy-dispersive spectroscopy (EDS) was performed to facilitate the isolation and re-analysis of isotopically unique U-bearing particles where the highest pr

Publikováno v: Journal of Analytical Atomic Spectrometry. 30:1100-1107
We utilized femtosecond laser ablation together with multi-collector inductively coupled plasma mass spectrometry to measure the uranium isotopic content of NIST 61x (x = 0, 2, 4, 6) glasses. The uranium content of these glasses is a linear two-compo

Validating mass spectrometry measurements of nuclear materials via a non-contact volume analysis method of ion sputter craters
Autor: David Willingham, Benjamin E. Naes, Albert J. Fahey
Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 303:655-662
A combination of secondary ion mass spectrometry, optical profilometry and a statistically-driven algorithm was used to develop a non-contact volume analysis method to validate the useful yields of nuclear materials. The volume analysis methodology w
