NIST Neutron Source Preconceptual Design

October 5, 2022
Author(s)
Dagistan Sahin, Osman Celikten, Robert Williams, Jeremy Cook, Abdullah Weiss, Thomas Newton, David Diamond, Charles F. Majkrzak, Hubert King, Joy Shen, Anil Gurgen, Eliezer Nahmani, Idan Baroukh, Lap-Yan Cheng
The National Bureau of Standards Reactor (NBSR) at the NIST Center for Neutron Research (NCNR) provides a safe and reliable neutron source for the thousands of visiting U.S. and international researchers annually. A new state-of-the-art research reactor

Periodic Table of the Elements

October 5, 2022
Author(s)
Karen Olsen
The periodic table contains NIST's latest critically evaluated data for atomic properties of the elements.

Architecture Definition in Complex System Design Using Model Theory

October 4, 2022
Author(s)
Charles Dickerson, Michael Wilkenson, Eugenie Hunsicker, Siyuan Ji, Mole Li, Yves Bernard, Graham Bleakley, Peter O. Denno
Architecture Definition, which is central to system design, is one of the two most used technical processes in the practice of model-based systems engineering. In this paper a fundamental approach to architecture definition is presented and demonstrated

Contactless Excitation of Acoustic Resonance in Thin Wafers

October 4, 2022
Author(s)
Gan Zhai, Yizhou Xin, Cameron Kopas, Ella Lachman, Mark Field, Josh Y Mutus, Katarina Cicak, Joe Aumentado, Zuhawn Sung, William Halperin
Contactless excitation and detection of high harmonic acoustic overtones in a thin single crystal are described using radio frequency spectroscopy techniques. Single crystal [001] silicon wafer samples were investigated, one side covered with a Nb thin

Density changes in amorphous silicon induced by swift heavy ions

October 4, 2022
Author(s)
Sjoerd Roorda, Amelie Lacroix, Stephanie Codsi, Gabrielle Long, Fan Zhang, Steven Weigand, Christina Trautmann
Pure and gold-doped amorphous silicon membranes were irradiated with swift heavy ions (75 MeV Ag or 1.1 GeV Au ions) and studied by small angle X-ray scattering. The samples that were irradiated with 1.1 GeV Au ions produced a scattering pattern consistent

Hybrid Quantum-Edge Computing: A New Computing Paradigm

October 4, 2022
Author(s)
Lijun Ma, Leah Ding
Edge computing has emerged to support the computational demand of delay-sensitive applications in which substantial computing and storage are deployed at the network edge in close proximity to data sources. The vision of a hybrid quantum-edge is to provide

Hyperspectral photon-counting optical time domain reflectometry

October 4, 2022
Author(s)
Anouar Rahmouni, Samprity Saha, Oliver T. Slattery, Thomas Gerrits
Optical time-domain reflectometry (OTDR) is one of the most used techniques for nondestructive characterization of optical fiber links. Although conventional OTDR exhibits good performance in classical network applications, photoncounting OTDR (ν-OTDR)

Portable polarization-entangled photon source & receiver toolset for quantum network metrology

October 4, 2022
Author(s)
Anouar Rahmouni, Thomas Gerrits, Paulina Kuo, Dileep Reddy, Lijun Ma, Xiao Tang, Oliver T. Slattery
A quantum network will consist of many physically separated nodes connected by quantum communication channels that distribute entanglement between them. Such nodes will require mechanisms for the generation, routing, and measurement of quantum states to

Towards entangled photon pair generation from SiC-based microring resonator

October 4, 2022
Author(s)
Anouar Rahmouni, Lijun Ma, Xiao Tang, Thomas Gerrits, Lutong Cai, Qing Li, Oliver T. Slattery
Entangled photon sources are fundamental building blocks for quantum communication and quantum networks. Recently, silicon carbide emerged as a promising material for integrated quantum devices since it is CMOS compatible with favorable mechanical

AI Assurance for the Public -- Trust but Verify, Continuously

October 3, 2022
Author(s)
Phillip Laplante, D. Richard Kuhn
Artificial intelligence (AI) systems are increasingly seen in many public facing applications such as self-driving land vehicles, autonomous aircraft, medical systems and financial systems. AI systems should equal or surpass human performance, but given

High-accuracy optical clocks based on group 16-like highly charged ions

October 3, 2022
Author(s)
Saleh Allehabi, Samuel Brewer, Vladimir Dzuba, Victor Flambaum, Kyle Beloy
We identify laser-accessible transitions in group 16-like highly charged ions as candidates for high-accuracy optical clocks, including S-, Se-, and Te-like systems. For this class of ions, the ground 3PJ fi ne structure manifold exhibits irregular
