Title: Neutron spectroscopy and spectral unfolding with ⁴He fast neutron scintillators

Abstract

Time-of-flight measurements were performed to determine the ⁴He pressurized fast neutron scintillation detectors response function and the ability of the detectors to be applied as a spectrometer. An experimentally validated neutron energy response function was used in conjunction with an iterative least squares unfolding technique to unfold a ²⁵²Cf spontaneous fission spectrum, a PuBe (α, n) spectrum, and a deuterium-deuterium (D-D) fusion reaction spectrum. In conclusion, the ability of the detectors to retain incident neutron energies makes them suitable for applications such as nuclear non-proliferation and spent nuclear fuel monitoring.

A Hierarchical Bayesian Approach to Neutron Spectrum Unfolding With Organic Scintillators

Journal Article Zhu, Haonan ; Altmann, Yoann ; Fulvio, Angela Di ; ... - IEEE Transactions on Nuclear Science

We propose a hierarchical Bayesian model and a state-of-the-art Monte Carlo sampling method to solve the unfolding problem, i.e., to estimate the spectrum of an unknown neutron source from the data detected by an organic scintillator. Inferring neutron spectra is important for several applications, including nonproliferation and nuclear security, as it allows the discrimination of fission sources in special nuclear material (SNM) from other types of neutron sources based on the differences of the emitted neutron spectra. Organic scintillators interact with neutrons mostly via elastic scattering on hydrogen nuclei and therefore partially retain neutron energy information. Consequently, the neutron spectrummore »« less

Time-of-flight neutron spectrum unfolding for mixed-oxide nuclear fuel and plutonium metal using a dual-particle imager

Journal Article Hamel, Michael C. ; Polack, J. Kyle ; Poitrasson-Riviere, Alexis ; ... - Nuclear Science Symposium and Medical Imaging Conference record

A dual-particle imager with sensitivity to both neutrons and photons has been developed for the detection of special nuclear material. This system has the capability to provide spectral information on detected sources that is useful for safeguard applications. In nuclear facilities with high photon background rates, neutron detection can aid in identification and verification capabilities. The dual-particle imager creates a reconstructed neutron spectrum by correlating neutron counts in pairs of liquid scintillators. The reconstructed spectrum, a combination of energy deposited and time-of-flight, contains resolution effects that blur the true, emitted source-spectrum. To reduce the impact of resolution effects, the reconstructedmore »« less

Multi-technique characterization of neutron fields from moderated /sup 252/Cf and /sup 238/PuBe sources

Conference Griffith, R V ; Slaughter, D R ; Patterson, H W ; ...

At the Lawrence Livermore Laboratory, /sup 252/Cf and /sup 238/PuBe neutron sources are used for calibration of personnel neutron dosimeters and neutron monitoring instrumentation. The sources, with emission rates of approximately 2 x 10/sup 9/ and 2 x 10/sup 7/n x sec/sup -1/, respectively, have been calibrated by the U.S. National Bureau of Standards. The sources are transferred into a 815-m/sup 3/ concrete calibration cell through a remotely operated pneumatic system. Calibrations can be made without source moderation, or with spherical moderators of aluminum, polyethylene, water, or deuterium oxide placed over the end of the pneumatic irradiation tube.

Measurement of the Fast Neutron Response for {sup 4}He Scintillation Detectors Using a Coincidence Scattering Method

Conference Kelley, R. P. ; Lewis, J. M. ; Murer, D. ; ...

Previous work has measured the neutron response of pressurized {sup 4}He scintillation detectors, however these studies only examine the response as a function of incident neutron energy. Since the detection mechanism in {sup 4}He detectors is elastic scattering, and the interacting neutron will only deposit a fraction of its incident kinetic energy in the detector gas, an examination of the response of the detector output to deposited energy is necessary to transform these detectors into instruments for neutron spectrometry. Using a combined time-of-flight (TOF) and coincidence scattering method, this paper further characterizes the {sup 4}He light response to fast neutronsmore »« less
Organic Scintillator for Real-Time Neutron Dosimetry

Journal Article Beyer, Kyle A. ; Di Fulvio, Angela ; Stolarczyk, Liliana ; ... - Radiation Protection Dosimetry

We have developed a radiation detector based on an organic scintillator for spectrometry and dosimetry of out-of-field secondary neutrons from clinical proton beams. The detector consists of an EJ-299-34 crystalline organic scintillator, coupled by fiber optic cable to a silicon photomultiplier (SiPM). Proof of concept measurements were taken with ¹³⁷Cs and ²⁵²Cf, and corresponding simulations were performed in MCNPX-PoliMi. Despite its small size, the detector is able to discriminate between neutron and gamma-rays via pulse shape discrimination. We simulated the response function of the detector to monoenergetic neutrons in the 100 keV–0 MeV range using MCNPX-PoliMi. The measured unfolded ²⁵²Cfmore »« less
