41 // (Description)
42 // This is a primitive scorer class for scoring Surface Flux.
43 // Current version assumes only for G4Tubs shape, and the surface
44 // is fixed on inner plane of the tube.
45 //
46 // Surface is defined at the innner surface of the tube.
47 // Direction R R+dR
48 // 0 IN || OUT ->|<- |
49 // 1 IN ->| |
50 // 2 OUT |<- |
51 //
52 // Created: 2007-03-29 Tsukasa ASO
53 // 2010-07-22 Introduce Unit specification.
54 // 2010-07-22 Add weighted and divideByArea options
55 // 2011-02-21 Get correct momentum direction in Flux_Out.
