// Comments
|
|
//
|
|
// This example intends to show how to use importance sampling and scoring
|
|
// in the mass (tracking) geometry.
|
|
// A simple geometry consisting of a 180 cm high concrete cylinder
|
|
// divided into 18 slabs of 10cm each is created.
|
|
// Importance values are assigned to the 18 concrete slabs in the
|
|
// detector construction class for simplicity.
|
|
// Pairs of G4GeometryCell and importance values are stored in
|
|
// the importance store.
