Phase I has proven that the current setup achieves better than 8mm spatial resolution for 2.2MeV prompt gammas. However, 1mm spatial resolution presents a significant challenge for the current setup due in part to limited timing resolution and count rate. A new analog ASIC will be developed to replace the current analog ASIC that will have better timing resolution and deliver higher count rates. I ...

Industrial facilities, manufacturing plants, and electric power plants that burn fossil fuels exhaust the combustion products to atmosphere through their smokestacks. Stack pollutant emissions are quantified using manual testing methods developed in the 1960s, which are prone to error if non-axial flow exists in a stack.Recently, NIST has been working on an improved technique of performing 3D flow ...

To evaluate the technical feasibility of prompt gamma neutron activation (PGAA) as an alternative to a set of standard destructive tests of concrete petrography including aggregate type, water/cement ratio, aggregate/binder ratio, density, chloride content and chloride bulk diffusion constant; and to determine the specifications for the design of a dedicated commercial laboratory-based PGAA facili ...

Methane, is the third most prevalent greenhouse gas whose atmosphere concentration is currently over 1.7 ppm. Methane is about 21 times more potent when compared to CO2. Even though its concentration in the atmosphere is more than 200 times lower than carbon dioxide, methane is responsible for 20% of the greenhouse effect. The main natural resources for methane include wetlands, termites and the o ...

methyst Research Inc. will design, fabricate and test a high uniformity, large area, low noise infrared trap-detector detector for the 1- 4.5 μm wavelength range. This state of the art detector will have a large area (e.g., 1-1.8 cm diameter active area) with a spatial variability of internal quantum efficiency of less than 0.1 % between 1 μm and 4.5 μm. In addition, the internal quantum effici ...

This Phase II project will continue the prototype development of a pharmaceutical spray quality audit system. The spray quality audit system will estimate the planar mass distribution, mass flux, and drop size of pharmaceutical sprays that are used in functional coating applications and inhalers. A prototype tomography system will be designed and fabricated and evaluated using various fluorophore.

A new radiometric vicarious calibration approach for the Suomi NPP VIIRS Day/Night Band’s (DNB) high gain stage (HGS) is proposed that will complement traditional, extended source, radiance-based calibrations, which are based on natural lunar illumination and not as accurate as desired. The proposed research will produce affordable, field-deployable, NIST-traceable point source lamps that can ac ...

The objective of the proposed work is to create low cost, low power sensors for autonomous measurement of ocean carbon. In our Phase I effort, we showed that Dioxide Materials’ miniature CO2 sensors have the speed and sensitivity to meet NOAA’s requirements for sensing ocean carbon. The objective of the proposed work is to further develop the sensors so that they can be used directly in NOAA ...

The accurate identification of seafood species and origin has become an extremely important topic in the food industry. Mislabeling a lower valued seafood product to represent a species of higher value constitute economic fraud. In addition, this mislabeling compromises proper geographic origin labeling and fishery management efforts. DNA barcoding for seafood species identification provides re ...

The objective of this proposal is to establish the feasibility of developing an integrated decision support tool that transforms the current time-consuming and reactive (post-design) sustainability assessment into a real-time, proactive approach available in the early phases of product design. This tool, called Sustainability Integrated into Early Design (SIED), will define and capture lifecycle-w ...
