I recreated out ‘universe’ with the earth surrounded by the atmospheres all enclosed in a box with the intention to detect neutrons and its secondary particles via a sensitive detector just outside of the space (its invisible at the moment). The problem is regardless of what I do (no matter if I beamOn 1 or 100 runs) the same image is shown (below). I followed the Hadr04 example and just changed the construction and material to make it realistic. It seems that no matter what, ProcessHits is not being called/ working. Below I have my detector files and physics lists. Any help appreciated!
