The following files are my input files and my output files.You can see some detectors output 0 although there might be some particles.I have increased the running times to 10^7,is there any ways to solve this problem? |

Do the particle tracks look reasonable? It is a large space, you could reduce the air box to be tighter around your ring of detectors, if you're not specifically trying to measure the scatter from distant air. I believe it would slightly increase the efficiency to use EGS_XYZGeometry for each of the detectors, each positioned exactly at the correct location originally, instead of using egs_transformed_geometry to move boxes around. This might not be worth the effort. I see that your runtime was only about 210s, so I'm not sure the issue. It's normal for a simulation to require hundreds of millions of histories (or even billions) for a low statistical uncertainty - try running the simulation longer. |

Thank you.I'm very glad that there is no wrong with my code.It's just a demo,I will run the simulation longer. |
