38 | // This is a primitive scorer class for scoring Surface Flux. |
---|
39 | // Current version assumes only for G4Box shape, and the surface |
---|
40 | // is fixed on -Z plane. |
---|
41 | // |
---|
42 | // Surface is defined at the -Z surface. |
---|
43 | // Direction -Z +Z |
---|
44 | // 0 IN || OUT ->|<- | |
---|
45 | // 1 IN ->| | |
---|
46 | // 2 OUT |<- | |
