Detailed Description

Factory for rectellipse aperture model beampipes.

This is the overlap of (boolean AND) a rectangle and an ellipse transversely. This factory is similar to the simple LHC factory and uses the intersection of an elliptical tube and a box. This method produces a solid shape, so to achieve a pipe, a smaller duplicate intersection solid is made for subtraction from the outer one. To achieve the angled faces, G4CutTubs is used and the rectangular box is made longer so the first intersection gives the angled face from the easier G4CutTubs primitive.

This factory requires four aperture parameters. Aper1,2 are the horizontal and vertical half widths of the rectangle respectively, and aper3,4 are the horizontal and vertical semi-axes of the ellipse. Note, will aper1,2 should be < aper1,2 otherwise an elliptical tube will be more efficient.
