Primary Radioactive Gas Standards (Excluding Radon)

Author(s)
Michael P. Unterweger
This paper presents an overview of the primary calibration of radioactive gas standards using length-compensated internal gas counters. The principal of length

Experimental Demonstration of Signal Extration for LISA

Author(s)
O Jennrich, R T. Stebbins, P L. Bender
We present a scheme for the signal extraction for LISA. The underlying principle is demonstrated and an experimental setup for testing thescheme is shown. We

Instrumentation for Old Gravity

Author(s)
J E. Faller
Instrumental capabilities for both relative and absolute gravity measurements have evolved over the past 40 years to the point where today measurements can be

uses of Small Particle Growth in Silane Discharges

Author(s)
G Bano, K Rozsa, Alan Gallagher
Silicon-based particles that grow in a silane radio frequency (RF) discharge are studied by light scattering. Average particle size and the corresponding

Transport of Atoms in a Quantum Conveyor Belt

Author(s)
A Browaeys, H H ffnert, C R. McKenzie, S L. Rolston, Kristian Helmerson, William D. Phillips
We have performed experiments using a 3D-Bose-Einstein condensate of sodium atoms in a 1D optical lattice to explore some unusual properties of band-structure

Blueprint for Radioanalytical Metrology CRM's

In 1977, the International Committee on Radionuclide Metrology's (ICRM) Low-Level Working Group (LLWG) workshop, a long-term blueprint for a new series of

SSE- and Noise-Optimized InGaAs Radiation Thermometer

Author(s)
Howard W. Yoon, Charles E. Gibson, V B. Khromchenko, George P. Eppeldauer
For the measurements of radiance temperatures in the range from 150 ?C to 1000 ?C, low uncertainties in the temperature measurements can be achieved by using

The Superconductive Critical Magnetic Field of Beryllium

Author(s)
Robert J. Soulen, J H. Colwell, William E. Fogle
We have measured the temperature dependence of the superconductive critical magnetic field of several samples of beryllium from three different sources. The

Applications of Micro-Ring Resonator Filter Devices

Author(s)
S T. Chu, B E. Little, Y Kokubun, W Pan
Recently reported micro-ring resonator filters have demonstrated their compactness and signal processing functions. These features are attractive for large
