Convolutional discrete Fourier transform method for calculating thermal neutron cross section in liquids
Rong Du, Xiao-Xiao Cai
Being exact at both short- and long-time limits, the Gaussian approximation is widely used to calculate neutron incoherent inelastic scattering functions in liquids. However, to ov…
Elastic neutron scattering models for NCrystal
Thomas Kittelmann, Xiao-Xiao Cai
The NCrystal library provides a range of models for simulation of both elastic and inelastic scattering of thermal neutrons in a range of material structures. This article presents…
Simulating neutron transport in long beamlines at a spallation neutron source using Geant4
Douglas D. DiJulio, Isak Svensson, Xiao Xiao Cai +2
The transport of neutrons in long beamlines at spallation neutron sources presents a unique challenge for Monte-Carlo transport calculations. This is due to the need to accurately…
NCrystal : a library for thermal neutron transport
Xiao-Xiao Cai, Thomas Kittelmann
An open source software package for modelling thermal neutron transport is presented. The code facilitates Monte Carlo-based transport simulations and focuses in the initial releas…
In-Beam Background Suppression Shield
V. Santoro, X. X. Cai, D. D. DiJulio +2
The long (3ms) proton pulse of the European Spallation Source (ESS) gives rise to unique and potentially high backgrounds for the instrument suite. In such a source an instrument c…
Using Back-Scattering to Enhance Efficiency in Neutron Detectors
Thomas Kittelmann, Esben Klinkby, Xiao Xiao Cai +3
The principle of using strongly scattering materials to recover efficiency in neutron detectors, via back-scattering of unconverted thermal neutrons, is discussed in general. Feasi…
