Alternative Reflectors for The NIST Neutron Source

June 18, 2023
Author(s)
Yaniv Shaposhnik, Osman Celikten, Jeremy Cook, Abdullah Weiss, Dagistan Sahin
A conceptual design of a replacement reactor at the NIST Center for Neutron Research (NCNR), referred to as the NIST Neutron Source (NNS), is underway in collaboration with the Brookhaven National Laboratory. The NNS reactor design favors the production of

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

The Very Small-Angle Neutron Scattering Instrument at the National Institute of Standards and Technology

February 27, 2022
Author(s)
John Barker, James Moyer, Steven Kline, G. Jensen, Jeremy Cook, Cedric V. Gagnon, Elizabeth Kelley, Jean Philippe Chabot, Nicholas C. Maliszewskyj, Chirag B. Parikh, Wangchun Chen, C. Glinka
A description and the performance of the Very Small-Angle Neutron Scattering (VSANS) Diffractometer at the National Institute of Standards and Technology are presented. The measurement range of the instrument extends over three decades of momentum transfer

Design of a neutron microscope based on Wolter mirrors

April 21, 2021
Author(s)
Daniel S. Hussey, B. Khaykovich, Jeremy C. Cook, David L. Jacobson, Jacob LaManna, Kiranmayee Kilaru, Brian Ramsey, M. V. Gubarev
The predominate geometry for a neutron imaging experiment is that of a pinhole camera. This is primarily due to the difficulty in focusing neutrons due to the weak refractive index, which is also strongly chromatic. Proof of concept experiments

A 3He beam stop for minimizing gamma-ray and fast-neutron background

August 6, 2016
Author(s)
Danyal J. Turkoglu, Robert G. Downing, Wangchun Chen, Dagistan Sahin, Jeremy C. Cook
Prompt gamma-ray activation analysis facilities with high neutron currents (≥109 s-1) generate triton-induced fast neutrons from 6Li-loaded collimators and beam stops at rates that soon damage gamma-ray detectors. We develop an alternative beam stop design

Experimental Characterization of the Advanced Liquid Hydrogen Cold Neutron Source Spectrum of the NBSR Reactor at the NIST Center for Neutron Research

August 1, 2015
Author(s)
Jeremy C. Cook, John G. Barker, J. Michael Rowe, Robert E. Williams, Cedric V. Gagnon, Richard M. Lindstrom, Richard Michael Ibberson, Dan A. Neumann
The recent expansion of the NIST Center for Neutron Research facility has offered a rare opportunity to perform an accurate measurement of the cold neutron spectrum at the exit of a newly-installed neutron guide. Using a combination of a neutron time-of

NGD Cold Neutron Prompt Gamma-ray Activation Analysis Spectrometer at NIST

April 1, 2015
Author(s)
Rick L. Paul, Dagistan NMN Sahin, Jeremy C. Cook, Christoph W. Brocker, Richard M. Lindstrom, Donna J. O'Kelly
A new instrument for cold neutron prompt gamma-ray activation analysis (CNPGAA) has been designed and constructed as part of the recent expansion of the cold neutron guide hall at the NIST Center for Neutron Research (NCNR). Located on neutron guide NGD
