Data associated with "Primary quantum thermometry of mm-wave blackbody radiation via induced state transfer in Rydberg states of cold atoms"

Data provided by  National Institute of Standards and Technology

Rydberg states of alkali atoms are highly sensitive to electromagnetic radiation in the GHz-to-THz regime because their transitions have large electric dipole moments. Consequently, environmental blackbody radiation (BBR) can couple Rydberg states together at ?s timescales. Here, we track the BBR-induced transfer of a prepared Rydberg state to its neighbors and use the evolution of these state populations to characterize the BBR field at the relevant wavelengths, primarily at 130 GHz.

Sim-PROCESD: Simulated-Production Resource for Operations and Conditions Evaluation to Support Decision-making

Data provided by  National Institute of Standards and Technology

Sim-PROCESD is a discrete event simulation package written in Python that is designed to model the behavior of discrete manufacturing systems. Specifically, it focuses on asynchronous production lines. It also provides functionality for modeling the degradation and maintenance of machines in these systems. Sim-PROCESD provides class definitions for manufacturing devices/components that can be configured by the user to model various real-world manufacturing systems.

A Technique for Optimal On-Wafer Device Spacing at Millimeter-Wave Frequencies

Data provided by  National Institute of Standards and Technology

This dataset contains the simulated data of a ground-signal-ground on-wafer probe landed on a microstrip variable-impedance device (DUT) with a 775 micron (um) microstrip line neighboring the device and without any line neighboring the device. Two variables were investigated in the data: the impedance of the DUT and the X,Y location of the neighboring line. The reflection coefficient of the probe was recorded from 1 Gigahertz (GHz) to 150 GHz.

SRM 2197, Lot LL-198 Low-Energy Charpy V-Notch Specimens (Self-Verification, 2 mm Striker)

Data provided by  National Institute of Standards and Technology

NIST self-verification Charpy specimens, such as from lot LL-198 here considered, are used by companies around the world to perform an indirect verification of a Charpy impact machine in accordance with with ASTM E23 and ISO 148-2. Customers test between 5 and 7 samples and compare their average value with the reference absorbed energy from the NIST certification tests, provided in a certificate. If within the specified limits (which depend on the reference test standard), their verification can be considered successful.

Forecasting demand data for critical materials

Data provided by  National Institute of Standards and Technology

Clean energy technologies (e.g., solar, wind, EVs) are vital in our transition to a decarbonized energy grid. Many clean energy technologies rely on critical materials that are prone to supply chain risks. As the demand for clean energy technologies grows, so will the demand for these critical materials. Anticipating critical material market dynamics becomes crucial for change makers in developing effective strategies to scale up the implementation of clean energy generating technologies.
