NIST Micronutrients Measurement Quality Assurance Program Analysis Tutorial

September 6, 2016
Author(s)
Katherine E. Sharpless, Jeanice M. Brown Thomas, David L. Duewer
Since 1984, the National Institute of Standards and Technology (NIST) has coordinated what is now known as the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat-soluble vitamins and carotenoids in human serum

Broadband Coherent Anti-Stokes Raman Scattering

August 11, 2016
Author(s)
Charles H. Camp
Broadband coherent anti-Stokes Raman scattering (BCARS) microspectroscopy is a unique label-free imaging modality that provides detailed chemical information at each pixel. In minutes, this technique captures a “hyperspectral” cube that co-registers

A 3He beam stop for minimizing gamma-ray and fast-neutron background

August 6, 2016
Author(s)
Danyal J. Turkoglu, Robert G. Downing, Wangchun Chen, Dagistan Sahin, Jeremy C. Cook
Prompt gamma-ray activation analysis facilities with high neutron currents (≥109 s-1) generate triton-induced fast neutrons from 6Li-loaded collimators and beam stops at rates that soon damage gamma-ray detectors. We develop an alternative beam stop design
