Detectors (scintillation, HPGe)

As a starting point for simulating the gamma ray detectors, which examples can be used from the G4 database to help with understanding the simulation of the gamma spectroscopy detectors? For example, scintillation detectors.

I started with exampleB1. Numerous people have done simulations of scintillation and semiconductor detectors, so Google may be of help too. If you are lucky you may end up certain commands and related scripts.

I also suggest Youtube where nowadays there are several videos for the beginners.
