|

// 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 primitive scorers via the Multi Functional Detector
|
||||
