34 // (Description)
35 // This is a primitive scorer class for 3D scoring cell flux.
36 // The Cell Flux is defined by a sum of track length divided
37 // by the geometry volume, where all of the tracks in the geometry
38 // are taken into account. e.g. the unit of Cell Flux is mm/mm3.
39 //
40 //
41 // If you want to score only tracks passing through the geometry volume,
42 // please use G4PSPassageCellFlux3D.
43 //
44 //
45 // Created: 2007-08-14 Tsukasa ASO
46 // 2010-07-22 Introduce Unit specification.
47 // 2011-03-24 Give Size and Segmentation for relicated volume in cylinder.
