Generalized Method for the Optimization of Pulse Shape Discrimination Parameters
Jianxin Zhou, Abdullah Abdulaziz, Yoann Altmann +1
Organic scintillators exhibit fast timing, high detection efficiency for fast neutrons and pulse shape discrimination (PSD) capability. PSD is essential in mixed radiation fields,…
Characterization of stilbene-d12 for neutron spectroscopy without time of flight
N. Gaughan, J. Zhou, F. D. Becchetti +4
We have experimentally characterized the light-output response of a deuterated trans-stilbene (stilbene-d12) crystal to quasi-monoenergetic neutrons in the 0.8 to 4.4 MeV energy ra…
Effect of natural gamma background radiation on portal monitor radioisotope unmixing
Matthew Weiss, Ming Fang, Yoann Altmann +2
National security relies on several layers of protection. One of the most important is the traffic control at borders and ports that exploits Radiation Portal Monitors (RPMs) to de…
Quantitative Imaging and Automated Fuel Pin Identification for Passive Gamma Emission Tomography
Ming Fang, Yoann Altmann, Daniele Della Latta +2
Compliance of member States to the Treaty on the Non-Proliferation of Nuclear Weapons is monitored through nuclear safeguards. The Passive Gamma Emission Tomography system is a nov…
A Hierarchical Bayesian Approach to Neutron Spectrum Unfolding with Organic Scintillators
Haonan Zhu, Yoann Altmann, Angela Di Fulvioand Stephen McLaughlin +2
We propose a hierarchical Bayesian model and state-of-art Monte Carlo sampling method to solve the unfolding problem, i.e., to estimate the spectrum of an unknown neutron source fr…
Robust Bayesian target detection algorithm for depth imaging from sparse single-photon data
Yoann Altmann, Ximing Ren, Aongus McCarthy +2
This paper presents a new Bayesian model and associated algorithm for depth and intensity profiling using full waveforms from time-correlated single-photon counting (TCSPC) measure…
