A list of radiation-induced materials modifications that are NIST traceable

Photonic Dosimeter and Process for Performing Dosimetry

NIST Inventors
Ronald Tosh , Zeeshan Ahmed , Ryan P. Fitzgerald and Nikolai Klimov
Patent Description Radiation-induced materials modification is ubiquitous. These applications rely on dosimetry to reliably deliver the desired amount of radiation to the right place. Currently the dosimetry standard is based on calorimetry of a large water phantom irradiated exclusively by Co-60
Schematic comparison of the conventional approach and this invention for a sample (analyte + solvent) with a strong solvent absorption band in the spectral range of interest.

Spectrum Adjuster and Producing a Pure Analyte Spectrum

NIST Inventors
Young Jong Lee
Patent Description This invention is a spectroscopic method that adjusts the incident light intensity as a function of wavelength to flatten the solvent-only transmitted light spectrum over an interesting wavelength range. When a solvent has a strong absorption band within an interesting spectral
Experminetal system configuration for Ultra-High Spectral Resolution Spectrometer Based on Electromagnetically-Induced Transparency

Direct Absolute Spectrometer for Direct Absolute Spectrometry

NIST Inventors
Lijun Ma , Xiao Tang and Oliver T. Slattery
Patent Description In future quantum communication systems, single photons, as the information carriers, are required to possess very narrow linewidths and accurate wavelengths for an efficient interaction with quantum memories. Spectral characterization of such single photon sources is necessary
A timeline of long distance communication techniques

Communication Linker for Communication Linking

NIST Inventors
Sergey Polyakov and Ivan Burenkov
Patent Description The US has the leading optical communication industry and one of the largest telecommunication markets. Our invention directly improves the underlying technology of the telecommunication infrastructure. Quantum Coherent Frequency Shift Keying (CFSK) receiver is a device that
an image showing several different charts and figures that is titled "High-Resolution imaging and spectroscopy at High Pressure: A Novel Liquid Cell for the TEM"

Vacuum Compatible Fluid Sampler

NIST Inventors
Glenn Holland , Samuel M. Stavis and James Alexander Liddle
Patent Description The transmission electron microscope (TEM), with its ability to deliver atomic-scale spatial, and < 100 meV spectroscopic resolution, has enabled countless breakthroughs in materials science. From the early days of TEM development, researchers have sought to use the power of this
Line drawing of high efficiency photon detection

High Efficiency Photon Detection

NIST Inventors
Alex Smolyanitsky
Patent Description A detection pixel includes a material that is chosen so that its (averaged) atomic number density leads to the Compton process being the dominant scattering mechanism in response to incident photons, leading to production of Compton electrons with sufficient number and kinetic

Optical Parametric Oscillator

NIST Inventors
John T. Woodward IV
Patent Description This invention is a light source that provides high-power (1W to 5W), narrow line-width (<1 nm), quasi-continuous wave (80 MHz) light that can be tuned in wavelength from 340 nm to 2300 nm. See figure below. The light source is fully automated, solid state, and fits on a
