Description
The McStas[1,2] neutron ray-trace simulation package is a versatile tool for simulating neutron instruments and experiments alike. McStas was first released from RISØ in 1998[3] and has since grown to become a widely accepted open source software, backed by an international collaboration and a large user community.
McStas applies Monte Carlo and ray-tracing methods for transport of neutrons in the cold and thermal energy range, as applied at large scale facilities, both at research reactors and spallation sources such as those available at ESS, ILL, PSI, ISIS, HIFR, SNS and J-PARC.
The contribution presents current status and recent developments of the software framework and will include key examples from recent and planned, future development.
