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…
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…
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…
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…
