Charge Offset and Noise in SET Transistors

July 1, 1998
Author(s)
Neil M. Zimmerman, J. L. Cobb
We report on several previous and ongoing investigations into the source of, and the amelioration of, the charge offset noise in SET (single-electron tunneling) transistors, made of Al/AlOx/Al tunnel junctions. Previous work has shown that significant time

Class A Fire Suppression Experiments (NISTIR 6191)

July 1, 1998
Author(s)
Daniel M. Madrzykowski, D W. Stroup
This section reports on two studies conducted at NIST on the suppression of wood crib fires and tire fires. An overview of previous research on the use of water based fire suppression agents on wood cribs and tires is provided. A burning pile of rubble or

Class D Fire Suppression Experiments.

July 1, 1998
Author(s)
R L. Vettori
To investigate the effectiveness of water based extinguishing agents on non alkali Class D fires, two series of fire suppression experiments were conducted. The first experimental series was conducted by Underwriters Laboratory at the facility located in

Comparison of the NIST and ENEA Air Kerma Standards

July 1, 1998
Author(s)
R F. Laitano, P J. Lamperti, M P. Toni
A comparison was made between the NIST and ENEA air kerma standards for medium energy x-rays and 60Co gamma rays. The comparison took place at ENEA in June 1994. Two different transfer chambers from NIST were used for the comparison. The measurements were

Conformance Testing Object-Oriented Frameworks Using JAVA

July 1, 1998
Author(s)
Kevin G. Brady, James A. St Pierre
This paper details the assumptions, decision processes, and conclusions reached during the development and implementation of a Conformance Testing Tool using the JAVA [JAVA] programming language, and the Object Management Group's (OMG's) Common Object

Dynamical Response of a Bose-Einstein Condensate to a Discontinuous Change in Internal State

July 1, 1998
Author(s)
M R. Matthews, D S. Hall, D S. Jin, J R. Ensher, C E. Wieman, Eric A. Cornell, F Dalfovo, C Minniti, S Stringari
A two photon transition is used to rapidly convert an arbitrary fraction of 87Rb atoms from a [F=1, m f=-1>condenstate to the [F=2,n f=2>state. Transferring the entire population imposes a discontinuous change on the condensate's mean-field repulsion

Experimental Demonstration of Some Aspects of LISA Interferometry

July 1, 1998
Author(s)
R T. Giaime, R T. Stebbins, P L. Bender, J E. Faller, J L. Hall
Plans are described to experimentally demonstrate at JILA a possible phase measurement technique for use in LISA interferometry. This demonstration will include use of a compact system for fringe generation and photodetection with realistic beam powers in

Experimental Noise Sources in the NIST Watt Balance

July 1, 1998
Author(s)
Richard L. Steiner, David B. Newell, Edwin R. Williams
The present NIST Watt Balance has a relative combined standard uncertainty of about 145 nW/W. The final results of this phase of the experiment are presented. Improvements in the Type B (nonstatistical) uncertainty contributions, along with several

Extension of Voltage Range for Power and Energy Calibrations

July 1, 1998
Author(s)
O. Petersons, Thomas L. Nelson, Nile M. Oldham, Gerald FitzPatrick
A special purpose ac voltage divider system having voltage ratios of 600 V, 480 V, 360 V, and 240 V to 120 V has been developed to extend the voltage range of primary electric power calibrations from 120 volts to 600 volts at power frequencies of 50 and 60
