Geant4 - an Object-Oriented Toolkit for Simulation in HEP

HepMCEx02
|
|
---------
|
|
|
|
This example demonstrates how to interface primary particles in Geant4
|
|
with various event generators via the HepMC Monte Carlo event interface.
|
|
This is another example having the same generator action as HepMCEx01,
|
|
but much simpler user control.
|
|
|
|
1. Primary Generator
|
|
|
|
H02PrimaryGeneratorAction has HepMCG4Interface as the generator.
|
|
There are two types of generators provided as samples. One generator reads
|
|
primary information from a HepMC Ascii file (data/example_MyPythia.dat).
|
|
The other one generates primaries directly invoking PYTHIA routines
|
|
in every event.
|
|
|
|
2. Geometry
|
|
|
|
A simplified collider-type geometry, which consists of
|
|
- endcap calorimeter (a set of tubes filled with lead),
|
|
- barrel calorimeter (tube filled with lead),
|
|
- barrel muon detector (8 sets of plates filled with Ar),
|
|
- endcap muon detecror, (a set of tubes filled with Ar) and
|
|
- uniform magnetic field along the z axis of 3 Tesla at the
|
|
central region.
|

|
3. Physics List
|
|
|
|
Full set of "ordinary" physics processes, which is the same one as
|
|
ExN04PhysicsList.
|
|
|
|
4. User actions
|
|
|
|
All particles except muons are killed in the calorimeter section.
