41 | // This is a primitive scorer class for scoring Surface Flux. |

42 | // Current version assumes only for G4Tubs shape, and the surface |
---|
43 | // is fixed on inner plane of the tube. |
---|
44 | // |
---|
45 | // Surface is defined at the innner surface of the tube. |
---|
46 | // Direction R R+dR |
---|
47 | // 0 IN || OUT ->|<- | |
---|
48 | // 1 IN ->| | |
---|
49 | // 2 OUT |<- | |
