Title: Development and Characterization of a High-Energy Neutron Time-of-Flight Imaging System

Abstract

We present that Los Alamos National Laboratory has developed a prototype of a high-energy neutron time-of-flight imaging system for the non-destructive evaluation of dense, massive, and/or high atomic number objects. High-energy neutrons provide the penetrating power, and thus the high dynamic range necessary to image internal features and defects of such objects. The addition of the time gating capability allows for scatter rejection when paired with a pulsed monoenergetic beam, or neutron energy selection when paired with a pulsed broad-spectrum neutron source. The Time Gating to Reject Scatter and Select Energy (TiGReSSE) system was tested at the Los Alamos Neutron Science Center’s (LANSCE) Weapons Nuclear Research (WNR) facility, a spallation neutron source, to provide proof of concept measurements and to characterize the instrument response. This paper will show results of several objects imaged during this run cycle. In addition, results from system performance metrics such as the Modulation Transfer Function and the Detective Quantum Efficiency measured as a function of neutron energy, characterize the current system performance and inform the next generation of neutron imaging instrument.

Neutron Imaging at LANSCE—From Cold to Ultrafast

Journal Article Nelson, Ronald Owen ; Vogel, Sven C. ; Hunter, James F. ; ... - Journal of Imaging

In recent years, neutron radiography and tomography have been applied at different beam lines at Los Alamos Neutron Science Center (LANSCE), covering a very wide neutron energy range. The field of energy-resolved neutron imaging with epi-thermal neutrons, utilizing neutron absorption resonances for contrast as well as quantitative density measurements, was pioneered at the Target 1 (Lujan center), Flight Path 5 beam line and continues to be refined. Applications include: imaging of metallic and ceramic nuclear fuels, fission gas measurements, tomography of fossils and studies of dopants in scintillators. The technique provides the ability to characterize materials opaque to thermal neutronsmore »« less

An unsuppressed array for gamma-ray coincidence measurements following neutron-induced reactions

Journal Article Yates, S W ; Warr, N V ; Brown, T B ; ... - Transactions of the American Nuclear Society

A four-detector array was developed for measuring gamma-gamma coincidences following inelastic neutron scattering--i.e., the (n,n{prime}{gamma}) reaction--with accelerator-produced neutrons. Following the initial success in these measurements, this array was moved to the Weapons Neutron Research (WNR) area at the Los Alamos Neutron Science Center (LANSCE) for coincidence measurements with higher-energy neutrons from the LANSCE/WNR unmoderated neutron spallation source. Additional measurements with monoenergetic accelerator-produced neutrons with energies up to 24 MeV are in progress at the University of Kentucky. The Kentucky gamma-ray spectrometer (KEGS) consists of four unsuppressed high-purity germanium (HPGe) spectrometers at backward angles, {approximately}125 deg, to the direction of themore »« less
The Manuel Lujan Jr. Neutron Scattering Center (LANSCE) experiment reports 1993 run cycle. Progress report

Technical Report Farrer, R ; Longshore, A

This year the Manuel Lujan Jr. Neutron Scattering Center (LANSCE) ran an informal user program because the US Department of Energy planned to close LANSCE in FY1994. As a result, an advisory committee recommended that LANSCE scientists and their collaborators complete work in progress. At LANSCE, neutrons are produced by spallation when a pulsed, 800-MeV proton beam impinges on a tungsten target. The proton pulses are provided by the Clinton P. Anderson Meson Physics Facility (LAMPF) accelerator and a associated Proton Storage Ring (PSR), which can Iter the intensity, time structure, and repetition rate of the pulses. The LAMPF protonsmore »« less

Los Alamos neutron source meets first test

Journal Article Robinson, A L - Science (Washington, D.C.); (United States)

26 April was a day for celebrating at the Los Alamos National Laboratory as jubilant researchers stored a beam in the Proton Storage Ring (PSR) on the very first attempt. The PSR is a $22-million addition to the Weapons Neutron Research (WNR) facility whose effect will be to convert the WNR into a world-class pulsed source for neutron scattering on a par with the British Spallation Neutron Source that recently entered the commissioning phase at the Rutherford Appleton Laboratory (l). The combined WNR/PSR facility will be dedicated this August as the Los Alamos Neutron Scattering Center (LANSCE). However, two importantmore »« less

LANSCE nuclear science facilities and activities

Conference Nelson, Ronald O

Nuclear science activities at the Los Alamos Neutron Science Center (LANSCE) encompass measurements spanning the neutron energy range from thermal to 600 MeV. The neutron sources use spallation of the LANSCE 800 MeV pulsed proton beam with the time-of-flight technique to measure properties of neutron-induced reactions as a function of energy over this large energy range. Current experiments are conducted at the Lujan Center moderated neutron source, the unmoderated WNR target, and with a lead-slowing-down spectrometer. Instruments in use include the DANCE array of BaF{sub 2} scintillators for neutron capture studies, the FIGARO array of liquid scintillator neutron detectors, themore »« less
