| - | * <span style="color:#ff0000"> dnaphysics </span>: This example simulates track structures in 100-micron side cube made of liquid water. The physics processes are defined using class '''G4EmDNAPhysics'''. [http://geant4-dna.in2p3.fr/styled-3/styled-8/index.html Here] you can find more information about the different physics process that are used to build class '''G4EmDNAPhysics''' . [http://geant4-dna.in2p3.fr/styled-3/styled-9/index.html Here] you can find how to build your own '''G4EmDNAPhysics''' class. | + | * <span style="color:#ff0000"> dnaphysics </span>: This example simulates track structures in 100-micron side cube made of liquid water.

The beam is shot from the center of the cube. The output of this tutorial is a root ntuple with type of particle, type of process, energy deposit and energy loss for every simulation step. |
| - | * <span style="color:#ff0000"> dnageometry </span>: This example simulates track structures of different charged particles within a simplified geometrical model of the DNA molecule in a cell nucleus. Proton beam is simulated using class '''G4ParticleGun'''. The output is a root ntuple with type of particle, type of process, energy deposit and energy loss for every simulation step. | + | * <span style="color:#ff0000"> dnageometry </span>: This example simulates track structures of different charged particles within a simplified geometrical model of the DNA molecule in a cell nucleus.

* <span style="color:#ff0000"> microbeam </span>: This example simulates the cellular irradiation beam line installed on the [http://www.cenbg.in2p3.fr/-AIFIRA-Home-?lang=en AIFIRA] electrostatic accelerator facility located at [http://www.cenbg.in2p3.fr/ CENBG], Bordeaux-Gradignan, France. This accelerator is mainly used to investigate the effects of low dose irradiation on living cells. A realistic cell phantom is obtained from confocal microscopy and from ion beam anlysis techniques. Alpha particles of 3 MeV are incident on this phantom. The output is dose deposited in the cell cytoplasm and in the cell nucleus. | * <span style="color:#ff0000"> microbeam </span>: This example simulates the cellular irradiation beam line installed on the [http://www.cenbg.in2p3.fr/-AIFIRA-Home-?lang=en AIFIRA] electrostatic accelerator facility located at [http://www.cenbg.in2p3.fr/ CENBG], Bordeaux-Gradignan, France.
