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…
Design and Characterization of an Optically-Segmented Single Volume Scatter Camera Module
Kevin Keefe, Hassam Alhajaji, Erik Brubaker +10
The Optically Segmented Single Volume Scatter Camera (OS-SVSC) aims to image neutron sources for nuclear non-proliferation applications using the kinematic reconstruction of elasti…
Design and Calibration of an Optically Segmented Single Volume Scatter Camera for Neutron Imaging
A. Galindo-Tellez, K. Keefe, E. Adamek +12
The Optically Segmented Single Volume Scatter Camera (OS-SVSC) aims to image neutron sources for non-proliferation applications using the kinematic reconstruction of elastic double…
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…
Interaction position, time, and energy resolution in organic scintillator bars with dual-ended readout
Melinda Sweany, Aline Galindo-Tellez, Joshua Brown +7
We report on the position, timing, and energy resolution of a range of plastic scintillator bars and reflector treatments using dual-ended silicon photomultiplier readout. These me…
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…
