|
// Comments
|
|
//
|
|
// This example intends to show how to use both importance sampling and a
|
|
// customized scoring making use of the scoring framework
|
|
// in a parallel geometry.
|
|
//
|
|
// A simple geometry consisting of a 180 cm high concrete cylinder
|
|
// is constructed in the mass geometry.
|
|
// A geometry is constructed in the parallel geometry
|
|
// in order to assign importance values to slabs
|
|
// of width 10cm and for scoring. The parallel world volume should
|
|
// overlap the mass world volume and the radii of the slabs is larger
|
|
// than the radius of the concrete cylinder in the mass geometry.
|
|
// Pairs of G4GeometryCell and importance values are stored in
|
|
// the importance store.
|
|
// The scoring uses the G4CellSCorer and one customized scorer for
|
|
// the last slab.
|
|
//
