Differing Physics for Tantalum Only

2.8 MeV electron hitting a 20 thousandths of an inch thick piece of Tantalum and then plotting the photon energies

Brem = Bremsstrahlung

Ion = Electron Ionization

MS = Electron Multiple Scattering

When simulating Ionization and Multiple Scattering in Tantalum, no photons were created.

Differing Physics for Aluminum Only

2.8 MeV electron hitting a 1/2 inch thick piece of Aluminum and then plotting the photon energies

Brem = Bremsstrahlung

Ion = Electron Ionization

MS = Electron Multiple Scattering

When simulating Ionization and Multiple Scattering in Aluminum, no photons were created.

Differing Physics while Changing Detector Geometry

2.8 MeV electron hitting air and then plotting the photon energies

PhEE = Photoelectric Effect

CS = Compton Scattering

GC = Gamma Conversion

At the time of these simulations, physics with muons, positrons, and generic ions is turned off. There is also a discrepancy between simulations that do not have these particle processes active.
