0003 ## General description
0004
0005 This example is provided by the Geant4-DNA collaboration.
0006
0007 These processes and models are further described at:
0008 http://geant4-dna.org

0010 Any report or published results obtained using the Geant4-DNA software shall
0011 cite the following Geant4-DNA collaboration publications:

0017 ## GEOMETRY DEFINITION
0018
0019 It is a simple box which represents a 'semi infinite' homogeneous medium.
0020
0021 Two parameters define the geometry :
0022 - the material of the box -- for Geant4-DNA it has to be water.
0023 - the full size of the box.
0024
0025 The default geometry is constructed in DetectorConstruction class.
0026
0027 ## PHYSICS LIST
0028
0029 PhysicsList is Geant4 modular physics list using G4EmDNAPhysics &
0030 G4EmDNAChemistry constructors.
0031
0032 ## AN EVENT: THE PRIMARY GENERATOR
0033
0034 The primary kinematic consists of a single particle starting at the center of
0035 the box. The type of the particle and its energy are set in the
0036 PrimaryGeneratorAction class, and can be changed via the G4 build-in commands
0037 of G4ParticleGun class.
0038 The chemistry module is triggered in the StackingAction class when all
0039 physical tracks have been processed.
0040
0041 ## OUTPUT
0042
0043 Physics initialization and the defined reaction table are printed.
0044 G4ITStepManager processes the chemical stage time step after time step.
0045 Chemical reactions are printed.

0047 ## HOW TO START
0048
0049 To run the example in batch mode
0050
0051 ./chem1 -mac beam.in
0052
0053 or
0054
0055 ./chem1
0056
0057 then the macro beam.in is processed by default
0058
0059 In interactive mode, run:
0060
0061 ./chem1 -gui
0062
0063 or
0064
0065 ./chem1 -gui gui.mac
