I defined two kinds of detector geometry which are expected to be equivalent, but they are not.
The first one is a full solid sphere (R1 = 0-100cm, position (0,0,0)). The another one is composed by two spheres(R2 =0-90cm, position(0,0,0)) and (R3 = 90-100cm, position(0,0,0)).
I incident same mount of energetic protons on the detector surface and detect the proton flux at r1 = 95cm and r2 = 85cm. The results of the two kinds of geometry are different both at r1 and r2. I think the difference is caused by the boundary of sphere2 and sphere3 at 90cm even the material of them are same. I want to know how to eliminate the effect caused by the boundary?
Please give me a help if you have any idea about this. Thank you in advance!
