Rotational Spectrum of Sarin

January 1, 2001
Author(s)
Angela R. Hight Walker, R D. Suenram, A C. Samuels, J O. Jensen, M W. Ellzy, J M. Lochner, D Zeroka

Sapphire Statistical Characterization and Risk Reduction Program

January 1, 2001
Author(s)
Donald McClure, Robert Cayse, David R. Black, Steven Goodrich, K Lagerloef, D Peter, Daniel C. Harris, Dale McCullum, Daniel H. Platus, Charles E. Patty, Robert S. Polvani
The Sapphire Statistical Characterization and Risk Reduction Program tested 1400 4-point flexure bars with different crystal orientations at different temperatures to establish a mechanical strength database for engineering design. Sapphire coupons were

Scaling Issues in the Measurement of Monolayer Films

January 1, 2001
Author(s)
Stephen M. Hsu, P M. McGuiggan, J Zhang, Y L. Wang, F Yin, Y P. Yeh, Richard S. Gates
An atomic force microscope (AFM), a surface forces apparatus (SFA), and a ball-on-inclined plane (BOIP) apparatus were used to measure the mechanical properties of thin films. The frictional force (lateral resistance) of a set of four samples with

SEM Sentinel - SEM Performance Measurement System

January 1, 2001
Author(s)
Bradley N. Damazo, Andras Vladar, Alice V. Ling, M A. Donmez, Michael T. Postek, Crossley E. Jayewardene
This paper describes the design and implementation of a system for monitoring the performance of a critical dimension measurement scanning electron microscope (CD-SEM). Experiments were performed for tests involving diagnosis of the vacuum system and

Sensor-Driven Fire Model Version 1.1 (NISTIR 6705)

January 1, 2001
Author(s)
William D. Davis, Glenn P. Forney
Modern building fire sensors are capable of supplying substantially more information to the fire service than just the simple detection of a possible fire. With the increase in the number of sensors installed in buildings for non-fire purposes, it is

Separation of Inner Shell Vacancy Transfer Mechanisms in Collisions of Slow Ar 17+ Ions with SiO 2

January 1, 2001
Author(s)
E Takacs, Z Ber nyi, John D. Gillaspy, L P. Ratliff, Ronaldo Minniti, J Pedulla, R Deslattes, N Stolterfoht
We have studied the spectrum of x-rays emitted when hydrogen-like argon ions impact silicon dioxide surfaces. Specifically, we were interested in the mechanism for creation of K-shell holes in the silicon target atoms, which can be filled with the release

SI Traceability of Force at the Nanonewton Level

January 1, 2001
Author(s)
David B. Newell, Jon R. Pratt, John A. Kramar, Douglas T. Smith, L Feeney, Edwin R. Williams
Although nanonewton force measurements are commonplace in industry, no National Measurement Institute supports a link to the International System of Units (SI) below one newton. The National Institute of Standards and Technology has launched a five-year
