McStas - A neutron ray-trace simulation package

McStas is a general tool for simulating neutron scattering instruments and experiments. It is actively supported by DTU Physics, NBI KU, ESS, PSI and ILL

Simulated scattering from a hollow-cylinder vanadium sample.

The plot shows the intensity of scattered neutrons (red is highest intensity). The sample is at the center of the sphere with the neutron beam coming from the left. Clearly seen is the shadowing effect of the sample causing a lower intensity opposite the beam. Also seen is the effect of the non-symmetric geometry of the sample, causing lower intensity directly above and to the side of the sample.

February 9th, 2021: Updated miniconda3 packages for v.2.7 and 3.0 on CentOS

Dear all,

We have recently discovered issues with binary-compatibility of some miniconda3-based Python modules in both 2.7 and 3.0 on CentOS. As a consequence, the related packages have been updated on the download page plus in our repo.
