37 | // This example intends to show how to use both importance sampling and a |
---|
38 | // customized scoring making use of the scoring framework |
---|
39 | // in a parallel geometry. |
---|
40 | // |
---|
41 | // A simple geometry consisting of a 180 cm high concrete cylinder |
---|
42 | // is constructed in the mass geometry. |
---|
43 | // A geometry is constructed in the parallel geometry |
---|
44 | // in order to assign importance values to slabs |
---|
45 | // of width 10cm and for scoring. The parallel world volume should |
---|
46 | // overlap the mass world volume and the radii of the slabs is larger |
---|
47 | // than the radius of the concrete cylinder in the mass geometry. |
---|
48 | // Pairs of G4GeometryCell and importance values are stored in |
---|
49 | // the importance store. |
---|
50 | // The scoring uses the G4CellSCorer and one customized scorer for |
---|
51 | // the last slab. |
---|
