I post a message in the category of electromagnetic process : http://hypernews.slac.stanford.edu/HyperNews/geant4/get/emprocess/1308.html.
I trie to simulate a microfocus x-ray tube by modelling only a electron beam in direction to a target.
I saw that some electrons cross the target without interaction. The target thick is sufficient to stop the electron (greater than range of these). It seems that the electron don't see the target, it is as if there was no target only galactic...
It's possible that the problem come from the step length ?
Thanks in advance for your time,
