McStas project is a general tool for simulating neutron scattering instruments.

McStas is a computer program (written in C) that enables you to model very precisely a neutron instrument described as a series of various components.

A source component shoots each neutron randomly (Monte-Carlo), and the particle is then propagated through the different instrument components.

These later act on the neutron characteristics (position, speed, direction, spin, etc.).

Usually, one installs some detectors along the neutron path to monitor its characteristics and flux.
