Dear G4 users,
I encountered one problem with scoring mesh. I have the following setup:
10 nm thick SiN layer ( box of 200 nm x 200 nm x 10 nm). This layer is in a vacuum environment.
An ideal detector is positioned directly on the bottom of SiN layer and it is divided into 200 x 200 pixels using scoring mesh (pixel size is 1nm x 1nm). An electron beam of 10 keV is used to irradiate the SiN layer. I want to calculate the number of electron reaching the pixels using scoring mesh (e.g. flatSurfaceCurrent. This works nicely for large pixel sizes but using small pixel size as described in this post does not work. The simulation gets stuck after some thousands events. This happen every time when I make the pixel size smaller. Is there a pixel size limit in geant4?
Thanks in advance I look forward to receive your helps and suggestions.
