Virtual Cybernetic Building Testbed

The NIST Virtual Cybernetic Building Testbed (VCBT) is a whole building emulator designed with enough flexibility to be capable of reproducibly simulating

VOC emissions chambers

In order to support the development of test methods and reference materials for volatile organic compounds (VOC) emissions from building materials and

Wind Tunnel

NIST’s wind tunnel can produce air speeds between 0.15 m/s and 40 m/s. The air speed reference is a Laser Doppler Anemometer (LDA) with an uncertainty of 2.5 %

X-ray Absorption Fine Structure (XAFS)

The XAFS station uses a tunable, monochromatic, and moderately high energy X-ray beam (4.5 keV to 23.5 keV) for X-ray absorption spectroscopy measurements. The

X-ray Backscatter Systems

X-ray backscatter systems are used for the screening of personnel for hidden weapons and other contraband. Unlike conventional radiographic x-ray systems

X-Ray Diffractometer

The Bruker D8 defractometer is a general purpose X-ray diffraction system. The instrument features easy reconfiguration of the X-ray optics for a variety of

X-Ray Reflectometer

The NCNR x-ray diffractometer is configured to allow both θ/2θ diffraction and reflectometry. Typically Cu radiation is used with minimum resolution of Δλ=0

X-Ray Residual Stress

The diffractometer is part of the Residual Stress Program with the main purpose of measuring strains/stresses. Other possible applications are the measurement
