Dear Colleagues I prepared slides showing the fix of sampling fraction calculation. I originally extended the detector to 5x the thickness to avoid leakage, which produced the overlap with flux return, adding extra material. This was missed

Dear Colleagues

I prepared slides showing the fix of sampling fraction calculation. I originally extended the detector to 5x the thickness to avoid leakage, which produced the overlap with flux return, adding extra material. This was missed by the overlap check. I reported that before, but had issues with my jobs and was able to finish calculations now, where I simply removed the flux return.

We can discuss it during next meeting.

Best regards, Leszek
