37 // Comments
38 //
39 // This example intends to show how to use both importance sampling and a
40 // customized scoring making use of the scoring framework
41 // in a parallel geometry.
42 //
43 // A simple geometry consisting of a 180 cm high concrete cylinder
44 // is constructed in the mass geometry.
45 // A geometry is constructed in the parallel geometry
46 // in order to assign importance values to slabs
47 // of width 10cm and for scoring. The parallel world volume should
48 // overlap the mass world volume and the radii of the slabs is larger
49 // than the radius of the concrete cylinder in the mass geometry.
50 // Pairs of G4GeometryCell and importance values are stored in
51 // the importance store.
52 // The scoring uses the primitive scorers via the Multi Functional Detector
53 //
