McStas
McStas is an open source software simulator for neutron
scattering instruments and experiments. The software consists of a
compiler that translates instrument and component definitions to C code.
McStas is based on a compiler that reads a high-level
specification language defining the instrument to be simulated and
produces C code that performs the Monte Carlo Simulation. The system is
very fast in use, both when setting up the instrument definition and
when doing calculations.
McStas is based on a unique design where an automatic
compilation process translates high-level textual instrument
descriptions into efficient ANSI-C code. This
design makes it simple to set up typical simulations and also gives
essentially unlimited freedom to handle more unusual cases.

Features include:
- Very fast in use
- Supports triple-axis
- Supports time-of-flight instruments
- Supports polarised neutrons
- Library of well-tested components that include most
standard elements of neutron scattering instruments, including
steady-state and pulsed sources, monochromators/analysers, guides,
collimators, vanadium and
powder samples, velocity selectors and choppers, and a variety of
detectors
- Generates histograms (tallies) as formatted (easy to
read) text files. Such text files may be read by the McStas internal
plotter using PGPLOT, but also using Matlab, Scilab, VRML/HTML (web
page), HDF/NeXus, XML/NeXus, Octave, IDL and more
- Comprehensive manual
