Quantum Electrical Measurements Programs/Projects in  PML

NIST physicist Rand Elmquist


In this photo, NIST physicist Rand Elmquist fills a cryogenic chamber with liquid helium in preparation for measuring the international standard for electrical resistance--the quantum Hall effect. U.S. laboratories and manufacturers use NIST electrical standards and calibrations for all kinds of measurements from home electricity usage to electrocardiograms to gene-mapping.
