This example shows how to use Geant4 as a generator for simulating
|
|
inelastic hadron-nuclear interactions.
|
|
|
|
The class HadronicGenerator is the "generator".
|
|
The main hadronic models (FTFP, QGSP, BERT, BIC, IonBIC, INCL)
|
|
and some combinations of two of them - in a transition energy region,
|
|
similarly to what happens in physics lists - are available.
|
|
See include/HadronicGenerator.hh for more detailed information.
|
|
|
|
The main, Hadr09.cc, shows an example of how to use it.
|
|
It samples randomly the projectile hadron, its energy, its direction
|
|
and the target material, and then it calls the generator.
|
|
Some information regarding the secondaries which are produced can be
|
|
printed out.
|
|
See the comments in Hadr09.cc for more information and how eventually
|
|
to change some of its configurations.
|
|
Notice that Hadr09.cc does nothing really useful: users should consider
|
|
to use eventually only the class HadronicGenerator.
|
|
|
|
Notice that the Geant4 run-manager is not used.
|
|
|
|
To build this example:
|
|
mkdir Build; cd Build
|
|
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo \
|
|
-DGeant4_DIR=/path-to-geant4-libraries ../.
|
|
make
|
|
|
|
To run it:
|
|
./Hadr09 [Hadr09.in]
|
|
|
|
which simulates 1000 hadron-nucleus collisions, randomnly selected, and
|
|
prints out some information about the secondaries produced in these
|
|
interactions. It takes only a few seconds to run.
|
|
Notice that the input file, Hadr09.in, which is empty, is not needed
|
|
by Hadr09, and can be omitted; however, it has been created because
|
|
is expected by system testing.
|
|
|
|
Note: this example has been included in Geant4 10.7, but it should work
|
|
also for early versions of Geant4, in particular 10.6, 10.5 and 10.4.
