Dear Jongseok,

If I understand correctly, you are plotting the energy deposited along the X direction (beam direction), the Y and Z being fixed. With such 3D detector division (you got something like 800^3 voxels), it seems to me that is very hard to see ( at least for statistical issues) a Bragg Peak.

So, I suggest you to sum the energy along the Y and Z direction in order to plot a B.P.

Another question is: are you sure you are at the center (or near to) of the beam? It seem to me, looking at the picture you have posted, that you are far from the center (that I think should be at Y=400 and Z=400 in your case).

Hope this helps, Enrico

P.S. Moreover you need a lot of memory to handle data (at least 8* 800^3 bytes!).
