McStas is a collaborative neutron ray‑tracing simulation package developed by Risø DTU, ILL, the University of Copenhagen, and PSI. The paper introduces McStas and discusses recent and ongoing simulation projects. The authors describe new features added in McStas releases 1.12c and 2.0. McStas has become the leading software for neutron scattering simulations and is actively used in the design and update of the European Spallation Source in Lund.
The McStas neutron ray-tracing simulation package is a collaboration between Risø DTU, ILL, University of Copenhagen and the PSI. During its lifetime, McStas has evolved to become the world leading software in the area of neutron scattering simulations for instrument design, optimisation, virtual experiments. McStas is being actively used for the design-update of the European Spallation Source (ESS) in Lund. This paper includes an introduction to the McStas package, recent and ongoing simulation projects. Further, new features in releases McStas 1.12c and 2.0 are discussed.
