Laser-Focused Nanofabrication: Beating of Two Atomic Resonances

June 10, 2002
Author(s)
E Jurdik, K van, J Hohlfeld, T Rasing, Jabez J. McClelland
We deposit a laser-collimated chromium beam onto a substrate through a laser standing-wave (SW) tuned above the atomic resonance at either of the two 52Cr transitions 7S 3rarr} 7P° 3 at 427.600 nm or 7S 3rarr} 7P° 4 at 425.553 nm. In both these cases the

June 1, 2002
Author(s)
Lawrence T. Hudson, Albert Henins, R Deslattes, J Seely, G Holland, R Atkin, L Marlin, D D. Meyerhofer, C Stoeckl
A new x-ray diagnostic has been commissioned recently at the OMEGA laser facility at the University of Rochester. It is a transmission curved crystal spectrometer designed primarily to characterize the hot-electron energy distribution of laser generated

X-Ray Tomography of Integrated Circuit Interconnects: Past and Future

November 1, 2001
Author(s)
Zachary H. Levine
An Al-W-silica integrated circuit interconnect sample was thinned to several micro υ and scanned across a 200 nm focal spot of a Fresnel zone plate operating at photon energy of 1573 eV. The experiment was performed on beamline 2-ID-B of the Advanced

Frequency Response Metrology for High-Speed Optical Receivers

March 1, 2001
Author(s)
Paul D. Hale, Tracy S. Clement, Dylan F. Williams
There are two types of optical sources whose modulation can be measured or calculated from fundamental principles: the hererodyne beat between two single- frequency lasers (frequency-domain) and the short pulse from a mode-locked laser (time-domain). While

The Ground and First Excited Torsional States of Acetic Acid

February 1, 2001
Author(s)
Vadim V. Ilyushin, E A. Alekseev, S K. Dyubko, S V. Podnos, I Kleiner, L Margules, G Wlodarczak, J Demaison, J Cosleou, B Mate, E N. Karyakin, G Y. Golubiatnikow, Gerald T. Fraser, R D. Suenram, Jon T. Hougen
A global fit of microwave and millimeter wave rotational transitions in the ground and first excited torsional states (vt = 0 and 1) of acetic acid (CH3COOH) is reported, which combines older measurements from the literature with new measurements from

Nonrandom Quantization Errors in Timebases

May 1, 2000
Author(s)
Gerard N. Stenbakken, D. Liu, J. A. Starzyk, Bryan C. Waltrip
Timebase distortion causes nonlinear distortion of waveforms measured by sampling instruments. When such instruments are used to measure the rms amplitude of the sampled waveforms, such distortions result in errors in the measured rms values. This paper

Annotation Collaboration Tool via SMIL (ACTS)

July 26, 1999
Author(s)
Wo L. Chang
The Web has emerged as a dominant mode of making information available and is increasingly seen as the medium to support collaboration across boundaries of geography and time. To realize this potential, the Web must support viewing and manipulating of

Tomographic Reconstruction of an Integrated Circuit Interconnect

January 1, 1999
Author(s)
Zachary H. Levine, A R. Kalukin, S P. Frigo, I McNulty, M Kuhn
An Al-W-silica integrated circuit interconnect sample was thinned to several micro υ and scanned across a 200 nm focal spot of a Fresnel zone plate operating at photon energy of 1573 eV. The experiment was performed on beamline 2-ID-B of the Advanced

Fire-Emulator Detector-Evaluation

October 28, 1998
Author(s)
Artur A. Chernovsky, William L. Grosshandler, Thomas G. Cleary, Michael D. Anderson
The performance of a fire detection system is determined as much by its ability to recognize correctly the non-fire state as to sense the presence of a real fire. Common fire detectors respond to particulate matter in the form of smoke from a flaming or

Interconnection Continuity Test for Packaged Functional Modules

March 3, 1998
Author(s)
Jan Obrzut
We developed an electrical test to evaluate interconnections in packaged, electrostatic-discharge (ESD) protected modules. The ESD protection circuit, which in modern integrated circuits is present at every I/O as an inherent part of the chip structure

A comprehensive experimental study was undertaken in this research effort to investigate cumulative damage in reinforced concrete circular bridge piers. Twelve identical quarter-scale bridge columns, designed and fabricated in accordance with current

Low Heat-Flux Measurements: Some Precautions

September 1, 1995
Author(s)
Thomas J. Ohlemiller, A F. Robertson
Simple experiments are described for the purpose of illustrating measurement errors and their avoidance during use of Gardon or Schmidt0Boelter toal heat flux sensors. These errors can assume serious proportions of the observed signal at flux levels below
