Low energy processes
The geometry is a cylinder of 5 cm radius filled with C6F6. It is designed to
test the 'low' energy processes, i.e. below 10 MeV.
The pictures (G4) (G3)
show the cylinder.
The incident particle is a gamma of 9 Mev, randomly shooted at the center
of the thank.
Most of the time, the gamma skips the tank without interact. When it interacts,
by gamma conversion or Compton scattering, the emitted charged particles
deposit their energy in C6F6.
Here 1000 events are surimposed. Only the tracks of charged particles are drawn.
The histogram shows the energy
deposited in C6F6 running 100000 events. Geant4/Geant3 comparison.
