How to align simulation with experiment?

in the other thread it was the total energy of the incident particle in one code block:

Do detector properties matter

Thank you, as well! So detector properties itself do not matter? In case there are any available(?). I assume there are as many features possible/available as I am able to define within the code? Or are there already any built-in/ready to use features which are good to use? In my case I constructed a G4box which I assigned to a sensitive detector. So I conclude my detector is actually just a box that does nothing but killing each particle it enters? This is my code: MySensitiveDetector::MyS…
