Description

McStas sample component using the NCrystal library for thermal neutron
transport in a single bulk material filling a single simple convex volume
(box, sphere or cylinder).

The geometrical layout of the volume is determined via the xwidth, yheight,
zdepth, and radius parameters, and the material being modelled is determined
via an NCrystal configuration string ("cfg-string").

For more information about NCrystal and cfg-strings, refer to the NCrystal wiki.
In particular, browse the available datafiles at Data-library and read about the
format of the cfg-string expected in the "cfg" parameter at Using-NCrystal.

For more complicated geometries, it might be desirable to use NCrystal via the
McStas Union components instead.

Note that the physics backend of this component will be whichever NCrystal
installation is available and associated with the "ncrystal-config" command.

Input parameters

Parameters in boldface are required; the others are optional.
