Nanometer-sized structures, surfaces and sub-surface phenomena have played an enormous role in science and technological applications and represent a driving

Quantum for Pressure

Author(s)
Jay H. Hendricks, Patrick F. Egan, Jacob E. Ricker, Jack A. Stone Jr., Kevin O. Douglass, Gregory F. Strouse
A team of NIST scientists is working to fundamentally change the way that the unit of pressure is realized and disseminated, an effort that will lead to the

Perspectives for a new realization of the pascal by optical methods

Author(s)
Jay H. Hendricks, Karl Jousten, Jack A. Stone Jr., Patrick F. Egan, Tom Rubin, Christof Gaiser, Rene Schodel, James A. Fedchak, Jacob E. Ricker, Jens Fluegge, Stephen P. Eckel, Julia K. Scherschligt, Daniel S. Barker, Kevin O. Douglass, Gregory F. Strouse, Uwe Sterr, Waldimir Sabuga
Since the beginning of measurement of pressure in the 17th century, the unit of pressure has been defined by the relationship of force per unit area. The

Cell-based refractometer for pascal realization

Author(s)
Patrick F. Egan, Jack A. Stone Jr., Jacob E. Ricker, Jay H. Hendricks, Gregory F. Strouse
We describe a method for determining density of helium via measurements of optical refractivity. In combination with the nist-equation of state, this allows

Stuck in a moment: A view from the MIRE

Author(s)
Patrick F. Egan, Jack A. Stone Jr., Jacob E. Ricker, Jay H. Hendricks
The next-generation pressure standards will be realized via gas density and the nist-equation of state. One way to access the density is through a measurement

Laser Refractometer as a Transfer Standard of the Pascal

Author(s)
Patrick F. Egan, Jack A. Stone Jr., Jacob E. Ricker, Jay H. Hendricks
We have developed a new low pressure sensor which is based on the measurement of (nitrogen) gas refractivity inside a Fabry-Perot (FP) cavity. We compare

Performance of a dual Fabry-Perot cavity refractometer

Author(s)
Patrick F. Egan, Jack A. Stone Jr., Jay H. Hendricks, Jacob E. Ricker, Gregory E. Scace, Gregory F. Strouse
We have built and characterized a refractometer that utilizes two Fabry-Perot cavities formed on a dimensionally stable spacer. In the typical mode of operation

Metrology for comparison of displacements at the picometer level

Author(s)
Jack A. Stone Jr., Patrick F. Egan, Jay H. Hendricks, Gregory F. Strouse, Douglas A. Olson, Jacob E. Ricker, Gregory E. Scace, Donavon Gerty
An apparatus capable of comparing displacements with picometer accuracy is currently being designed at NIST. In principle, we wish to compare one displacement

Weak value thermostat with 0.2 mK precision

Author(s)
Patrick F. Egan, Jack A. Stone Jr.
A new laser-based thermostat sensitive to 0.2 mK at room temperature is reported. The method utilizes a fluid-filled prism and interferometric weak value

Absolute refractometry of dry gas to ±3 parts in 109

Author(s)
Patrick F. Egan, Jack A. Stone Jr.
We present a method of measuring the refractive index of dry gases absolutely at 632.8 nm wavelength using a Fabry-Perot cavity with an expanded uncertainty of
