W-band dual channel AM/PM noise measurement system - an update

Author(s)
Archita Hati, Craig Nelson, J Nava, David A. Howe, Fred L. Walls, Huascar Ascarrunz, Justin Lanfranchi, Bill Riddle
We discuss the performance of a W-band (92-96) GHz amplitude modulated (AM) and phase modulated (PM) noise measurement system. The system uses two nearly

Impedance Measurements of Inertance Tubes

Author(s)
Michael A. Lewis, Peter E. Bradley, Ray Radebaugh
The flow impedance of an inertance tube 5.74 mm inside diameter and 2.36 m long coupled to various reservoir volumes was measured and compared with that

Dynamic Modeling and Vibration Analysis of a UHV Scanning Tunneling

Author(s)
Sumanth B. Chikkamaranahalli, R. R. Vallance, Bradley N. Damazo, Richard M. Silver, James D. Gilsinn
Techniques based on scanning probe microscopy (SPM) are used to fabricate surface structures with dimensions ranging from 10 - 100mm. These structures have been

Chip-Scale Atomic Clocks at NIST

Author(s)
John E. Kitching, Svenja A. Knappe, Li-Anne Liew, John Moreland, Hugh Robinson, P Schwindt, V Shah, Vladislav Gerginov, Leo W. Hollberg
We describe recent efforts to develop microfabricated atomic frequency references capable of supporting a wide variety of commercial and military systems such

Microfluidic Interfacial Tensiometry

Author(s)
Steven D. Hudson, J Cabral, Wenhua Zhang, Jai A. Pathak, Kathryn L. Beers
Immiscible fluids find diverse applications, yet their interfacial tension σ remains a fundamental property that governs their performance. Therefore, accurate

Microfabricated Atomic Clocks and Magnetometers

Author(s)
Svenja A. Knappe, P Schwindt, Vladislav Gerginov, V Shah, Hugh Robinson
We describe recent research at NIST directed towards the development of microfabricated atomic clocks and magnetometers based on coherent population trapping

NIST Realization of the ITS-90 Gallium Fixed Point

Author(s)
Gregory F. Strouse
As defined by the International Temperature Scale of 1990 (ITS-90), the gallium melting-point cell (29.7646 C) is used in the calibration of standard platinum

Stabilization of SPRTs for ITS-90 Calibrations

Author(s)
Dennis B. Minor, Gregory F. Strouse
At the National Institute of Standards and Technology (NIST), the ITS-90 calibration of standard platinum resistance thermometers (SPRTs) is performed in the
