Electromagnetic PhysicsList
---------------------------
The example of physics list for standard electromagnetic physics
package is presented in the subdirectory
electromagnetic/standard
The corresponding files are PhysicsList.cc, .hh
Physics list is equipped by the messenger, which allows to set
cuts and to define modules of physics to be used.
The following modules can be activated:
1. "standard" - (alternative) standard EM physics (current version)
2. "standard70" - (alternative) standard EM physics (development version)
3. "g4v52" - (alternative) standard EM physics (version G4 5.2p02)
4. "high_energy" - add high energy processes
5. "step_limit" - add step limit for charged particles
6. "decay" - add list of default decays
To activate a specific module the UI command can be used:
"/testem/phys/addPhysics title"
By default "standard" module is loaded.
The PhysicsList options can be defined via G4EmProcessOptions
class, the example of the usage is in the PhysicsList class
It is NOT assumed that files from this subdirectory will be
compiled directly. User can copy or link these files to
his/her application, to modify this example according to the
particular application.
It is assumed that user will add modules to this PhysicsList.
This PhysicsList approach is used in tests of the standard
electromagnetic package. Similar PhysicsLists can be found out
in advance examples.
The direct test of this PhysicsList is performed in the example
examples/extended/electromagnetic/TestEm2, TestEm9
