Project Summary
McStas and McXtrace are ongoing projects to create a general tool for simulating neutron (McStas) and X-ray (McXtrace) scattering instruments. The two code variants are distributed independently, but share as much infrastructure and tools as possible. Together they are known under the name of McCode.
Both McStas and McXtrace are based on a code-generation mechanism where a high-level specification language defines the instrument to be simulated and the mcstas/mcxtrace code generator produces C code that performs the Monte Carlo Simulation.
McStas and McXtrace both come with comprehensive manuals and a libraries of well-tested components that include most standard elements of neutron- and X-ray- scattering instruments respectively.
