Disentangling mixed neutron fields: multi-source identification from few detected events
David Breitenmoser, William Heriot, Peter Marleau +2
Identifying neutron-emitting materials is central to nuclear nonproliferation, safeguards, nuclear forensics, and emergency response, yet remains difficult when several sources con…
A comparison of the neutron detection efficiency and response characteristics of two pixelated PSD-capable organic scintillator detectors with different photo-detection readout methods
J. Balajthy, P. Marleau, M. Sweany
We characterize the performance of two pixelated neutron detectors: a PMT-based array that utilizes Anger logic for pixel identification and a SiPM-based array that employs individ…
Characterization of a silicon photo-multiplier array with summing board as a photo-multiplier tube replacement in organic scintillator assemblies
Melinda Sweany, Peter Marleau, Chris Allwork +2
We report on the energy, timing, and pulse-shape discrimination performance of cylindrical 5 cm diameter x 5 cm thick and 7 cm diameter x 7 cm thick {\it trans}-stilbene crystals r…
Single-Volume Neutron Scatter Camera for High-Efficiency Neutron Imaging and Spectroscopy
Joshua Braverman, James Brennan, Erik Brubaker +9
Neutron detection provides an effective method to detect, locate, and characterize sources of interest to nuclear security applications. Current neutron imaging systems based on do…
Characterizing Subcritical Assemblies with Time of Flight Fixed by Energy Estimation Distributions
Mateusz Monterial, Peter Marleau, Sara Pozzi
We present the Time of Flight Fixed by Energy Estimation (TOFFEE) as a measure of the fission chain dynamics in subcritical assemblies. TOFFEE is the time between correlated gamma…
Source detection at 100 meter standoff with a time-encoded imaging system
J. Brennan, E. Brubaker, M. Gerling +6
We present the design, characterization, and testing of a laboratory prototype radiological search and localization system. The system, based on time-encoded imaging, uses the atte…
Application of Bayes' theorem for pulse shape discrimination
Mateusz Monterial, Peter Marleau, Shaun Clarke +1
A Bayesian approach is proposed for pulse shape discrimination of photons and neutrons in liquid organic scinitillators. Instead of drawing a decision boundary, each pulse is assig…
Single-View 3D Reconstruction of Correlated Gamma-Neutron Sources
Mateusz Monterial, Peter Marleau, Sara A. Pozzi
We describe a new method of 3D image reconstruction of neutron sources that emit correlated gammas (e.g. Cf-252, Am-Be). This category includes a vast majority of neutron sources i…
Multiplication and Presence of Shielding Material from Time-Correlated Pulse-Height Measurements of Subcritical Plutonium Assemblies
Mateusz Monterial, Peter Marleau, Marc Paff +2
We present the results from the first measurements of the Time-Correlated Pulse-Height (TCPH) distributions from 4.5 kg sphere of -phase weapons-grade plutonium metal in five co…
The Physics and Nuclear Nonproliferation Goals of WATCHMAN: A WAter CHerenkov Monitor for ANtineutrinos
M. Askins, M. Bergevin, A. Bernstein +23
This article describes the physics and nonproliferation goals of WATCHMAN, the WAter Cherenkov Monitor for ANtineutrinos. The baseline WATCHMAN design is a kiloton scale gadolinium…
Advanced Scintillator Detector Concept (ASDC): A Concept Paper on the Physics Potential of Water-Based Liquid Scintillator
J. R. Alonso, N. Barros, M. Bergevin +47
The recent development of Water-based Liquid Scintillator (WbLS), and the concurrent development of high-efficiency and high-precision-timing light sensors, has opened up the possi…
Planning the Future of U.S. Particle Physics (Snowmass 2013): Chapter 8: Instrumentation Frontier
M. Demarteau, R. Lipton, H. Nicholson +211
These reports present the results of the 2013 Community Summer Study of the APS Division of Particles and Fields ("Snowmass 2013") on the future program of particle physics in the…
Coherent Scattering Investigations at the Spallation Neutron Source: a Snowmass White Paper
D. Akimov, A. Bernstein, P. Barbeau +54
The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory, Tennessee, provides an intense flux of neutrinos in the few tens-of-MeV range, with a sharply-pulsed timing st…
Improved Fast Neutron Spectroscopy via Detector Segmentation
N. S. Bowden, P. Marleau, J. T. Steele +3
Organic scintillators are widely used for fast neutron detection and spectroscopy. Several effects complicate the interpretation of results from detectors based upon these material…
