The 1 cm squared microchip used for NIST’s Johnson Noise Thermometry work, fabricated at the Boulder, Colo., campus.
NIST has recently made substantial improvements to its Johnson-noise thermometry system, which is playing a vital role in the worldwide effort to determine the value of a key physical constant in time for the impending redefinition of the International System of Units (SI) in 2018. The system is now capable of yielding statistical uncertainties 10 times smaller than its
PTBnews 1.2021 Ball plates and hole plates are measurement standards typically used to ensure the traceability of coordinate measuring machines. To arrange the plates vertically, one single supporting stand is often used that is placed […]
Researchers at the National Institute of Standards and Technology (NIST) have produced and precisely measured a spectrum of X-rays using a new, state-of-the-art machine. The instrument they used to measure the X-rays took 20 years […]
April 25, 2018 In an advance that could shrink many measurement technologies, scientists at the National Institute of Standards and Technology (NIST) and partners have demonstrated the first miniaturized devices that can generate desired frequencies, […]
