The gallery will show a few basic results, and will illustrate some characteristic features of the Geant4 electromagnetic physics.
From Geant3 to Geant4
A brief overview
Thin layer 1: multiple scattering
Thin layer 2: energy deposit , energy spectra
Thin layer 3: transmission through foils
Stepping: DEEMAX, STMIN .. etc..
Production threshold expressed in range
Production of secondaries and geometry
Stability of results versus cuts
Independance from the system of units
