Cylinder geometry component for Union components
Author: Mads Bertelsen
Origin: University of Copenhagen
Date: 20.08.15
Part of the Union components, a set of components that work together and thus sperates geometry and physics within McStas. The use of this component requires other components to be used.
1) One specifies a number of processes using process components 2) These are gathered into material definitions using Union_make_material 3) Geometries are placed using Union_box/cylinder/sphere, assigned a material 4) A Union_master component placed after all of the above
Only in step 4 will any simulation happen, and per default all geometries defined before this master, but after the previous will be simulated here.
There is a dedicated manual available for the Union_components
The position of this component is the center of the cylinder, and it thus extends yheight/2 up and down along y axis.
It is allowed to overlap components, but it is not allowed to have two parallel planes that coincides. This will crash the code on run time.
Parameters in boldface are required; the others are optional.
