We present the first measurements of energy-dependent light output from carbon recoils in the liquid organic scintillator EJ-309. For this measurement, neutrons were produced by an associated particle deuterium–tritium generator and scattered by a

An accurate model of the nonlinear detector response of organic scintillators to neutrons is required to correctly simulate fast neutron detection, as well as interpret measured pulse height data. Several empirical and semi-empirical models are avail

A solution-grown stilbene detector was used in several experiments with plutonium samples including plutonium oxide, mixed oxide, and plutonium metal samples. Neutrons from different reactions and plutonium isotopes are accompanied by numerous gamma

Proton therapy facilities use high-energy proton beams to destroy cancerous cells with greater specificity than photon-based approaches. However, due to the high energy of these protons, secondary radiation is produced through interactions with the p

Neutron sources whose neutrons can be tagged according to their time of emission are extremely useful because time-of-flight spectroscopy can be used to accurately measure their neutron energy spectrum. Sources utilizing the 9Be(α, n)12C reaction ex

Simulations of secondary neutron and gamma-ray production from the 11B(d,n)12C and 27Al(d,n)28Si reactions were conducted using an MCNPX extension called MCUNED. MCUNED enables simulation of deuteron-based nuclear reactions. Deuteron libraries from t
