A Summary of Heat-Flux Sensor Calibration Data

October 12, 2021
Author(s)
A V. Murthy, Gerald T. Fraser, D P. DeWitt
This paper presents a statistical evaluation of the responsivity data on a number of heat-flux sensors, calibrated using an electrical substitution radiometer as a transfer standard up to 5 W cm-2. The sensors, furnished by the customers, were of circular

A Two-Channel R-Matrix Analysis of Magnetic Field Induced Feshbach Resonances

October 12, 2021
Author(s)
N Nygaard, Barry I. Schneider, Paul S. Julienne
A Feshbach resonance arises in cold atom scattering due to the complex interplay between several coupled channels. However, the essential physics of the resonance may be encapsulated in a simplified model consisting of just two coupled channels. In this

Absorption Spectroscopy of EBT Model GAFCHROMIC TM Film

October 12, 2021
Author(s)
Slobodan Devic, Tomic Nada, Zhiyu Pang, Jan Seuntjens, Ervin Podgorsak, C K. Ross, Norman V. Klassen, Christopher G. Soares
The introduction of radiochromic films has solved some of the problems associated with conventional 2D radiation detectors. Their high spatial resolution, low energy dependence and near tissue-equivalence make them ideal for measurement of dose

Accelerator Mass Spectrometry Analysis of Carbonaceous Aerosols Captured in High Alpine Snow

October 12, 2021
Author(s)
R H. Weissenbok, Lloyd A. Currie, C Grollert, W Kutschera, J L. Marolf, A Priller, H Puxbaum, William N. Rom, P Steier
The capability for Accelerator Mass Spectrometry (AMS) to perform submilligram 14C measurements has considerable implications for environmental carbon research, especially for tracer studies of low concentration carbonaceous aerosols in remote regions. In

Acoustoelasticity, Theory and Experiment

October 12, 2021
Author(s)
L Jiang, Regis J. Kline, Y Yacobi, E Drescher-Krasicka
As a promising tool to characterize residual stress in engineering structural components, acoustoelasticity has been the subject of a great deal of research over the past forty years. Although considerable achievements have been derived, most approaches of

Additive-Containing Rinses for LER and Defectivity Control During High-Resolution Resist Patterning

October 12, 2021
Author(s)
D L. Goldfarb, S D. Burns, M Angelopolous, S Skordas, R L. Burns, M C. Lawson, C J. Brodsky, V Vishnu, E Jablonski, Vivek Prabhu, Ronald L. Jones, B D. Vogt, Christopher Soles, Eric K. Lin, Wen-Li Wu
The addition of a surface conditioning agent to the de-ionized water rinse used to quench the photoresist development process is an attractive methodology that can afford a controlled decrease in resist line edge roughness (LER) or a reduction in

Advanced Laser Cooling for the Atomic Space Clock

October 12, 2021
Author(s)
V Boyer, L Lising, S L. Rolston, William D. Phillips
An atomic clock works by comparing the frequency of a local oscillator (a micrwave generator) with the hyperfine transition of the cesium atom at 9.2 GHz. In general, the precision of a clock is limited by the observation time. For an atomic clock, it is

Advances in Magnetometry Through Miniaturization

October 12, 2021
Author(s)
A Edelstein, J Burnette, Greg Fischer, S F. Cheng, William F. Egelhoff Jr., Robert McMichael, E Nowak
Recent innovations may lead to magnetic sensors that are smaller, more sensitive and/or cost less than current magnetometers. Examples of this are the chip scale atomic magnetometer, magnetic tunnel junctions with MgO barriers, and a device for minimizing
