Due to overlap with the Uniformed Services University of the Health Sciences (USUHS) in missions, scientific interests, expertise, and instrumental requirements
A program for the development of dosimetry standards for radiobiology was launched through a highly successful workshop. The NIAID/NCI/NIST-sponsored workshop
In an effort to both reduce and improve the monitoring of radiation dose delivered to patients during computed tomography (CT) procedures, the Dosimetry Group
NIST researchers in the Biomolecular Structure and Function Group are involved in a joint research program with scientists from the University of Maryland
Much of the activity of the UV Physics Group is aimed at supporting the R&D effort by the microelectronics industry to develop Extreme Ultraviolet Lithography
Light can interact with mechanical systems in interesting and useful ways, not only probing the mechanical motion with spectacular sensitivity, but also driving
Optical-frequency combs are versatile laser sources for precision, ultrabroadband measurements, including with time, frequency, chemicals, digital information
The natural world is a magnificent place with observable, via measurement and inference, physical structures spanning at least 43 orders of magnitude in space
Conventional techniques for analyzing chemical composition, such as infrared (IR) microscopy often miss critically important nanoscale details. To overcome this
Single photons are the fundamental particles for all optical measurements. Single photon detectors made from avalanche photodiodes or photomultiplier tubes are
Reference radiation beams using a tungsten target and silver, rhodium, molybdenum and aluminum filters at 20 kVp to 50 kVp were developed to model digital
The Newtonian constant of gravitation G is one of the most fundamental constants of classical physics. Recent measurements of G are in disagreement, with

The OOF project seeks to provide flexible software for finite-element modeling the behavior of real microstructures, with meshes derived from micrographs.
The very best atomic clocks today are known as optical clocks, because their timebase resides at a very high frequency (~10 15 Hz), corresponding to the optical
The Optical and Microwave Spectroscopy of Microelectronic Systems program in the Spin Electronics group applies best-in-the-world and novel microwave and
We develop novel inelastic scattering methodologies to probe, quantify, and control key magnetic phenomena in 2D materials for applications in beyond CMOS
Accurate characterization of photonic equipment is important for optical communications, medical devices, semiconductor lithography, manufacturing and materials
Artificial intelligence increasingly affects many aspects of society. New computational hardware based on information-processing in the brain is being developed
Our multifaceted program provides numerous outputs to assist our customers. First, we develop and evaluate a variety of measurement techniques that provide
