Vitess 3.8 : a modernized framework for Monte Carlo neutron tracing simulations
Abstract
VITESS is a modular Monte Carlo simulation package for modeling and optimizing neutron scattering instruments through ray tracing of neutrons. The latest release, VITESS 3.8 , introduces major advances in functionality and software infrastructure. They include new source modules for integrating external moderator simulations and artificial-intelligence-based flux modeling, as well as prism for beam deflection and crystalline material simulations via NCrystal . Existing modules have been extended to support spin-dependent scattering, advanced monochromator motions and improved polarization handling. The update also includes a Git-based continuous integration system ensuring reproducibility.
