The McStas instrument simulation tool has been widely used for designing and optimising the ESS instrument suite. This contribution will outline how the ESS DMSC makes use of McStas for preparation of the data pipeline and transitioning from “as designed” to “as built” models. We will further outline lesser-known features in McStas and related projects to aid beamline staff in the...

VITESS is a software package to simulate all kinds of instruments at continuous and pulsed neutron sources. It enables virtual experiments, i.e. the propagation of the neutron beam to the sample position, scattering of neutrons at the sample, and determination of their spatial (and temporal) distribution at the detector.
The output of this simulation can be used to feed data evaluation...
