Question beginner needs help with simple example

From: John <>

I need help with a simple example. I am working for a medical physicist that wants me to simulate 200keV electrons hitting a very thin aluminum sheet. The information that he wants to get from this is how many electrons have scattered off of the sheet, how many electrons stay in the sheet, and how many transmit through. Does anyone have any suggestions? Should I use calorimeters or make the aluminum sheet a sensitive detector. I don't know how to track these things! Also, is it possible to only shoot electrons from a particle gun? Because I'm using low energy electrons and it keeps telling me that I need to include positrons and gammas. Please help! I don't understand Geant4 very well at all! Does anyone have any suggestions for a good tutorial or something? I didn't find the application developers manual very helpful. Thanks!!!
