Hi,

Thank you very much for your reply.

The geometry is pretty simple, I have two boxes (3 m and 2.995 m) inside each other, the bigger one made of Aluminium and the smaller one made of air, to create a box shell of aluminium with a thickness of 5 mm. There is a 1 m cube made of water at the center. I have the 1x1x1 m scoring mesh located at the (0,0,0). The particles are generated uniformly on a 4x4 m plane some 30 meters away.

I was doing the simulation using just 500 protons with 1 GeV energy. I increased number of the primary particles to 5000 and now the results are closer: 19514 GeV in 1 bin, 17587 GeV in 125 bins and 17865 in 1000 bins.

In order to measure total energy deposit or dose in a 1 cubic meter volume as in this application, one would get more accurate results using more bins or less?
