|
||||
\section Hadr06_s1 MATERIALS AND GEOMETRY DEFINITION
|
||||
|
||||
The geometry is a single sphere (absorber) of an homogenous material.
|
||||
|
||||
Two parameters define the geometry :
|
||||
- the radius of the sphere
|
||||
- the material of the sphere
|
||||
|
||||
The default geometry (R=30 cm of water) is built in
|
||||
DetectorConstruction, but the above parameters can be changed interactively
|
||||
via commands defined in DetectorMessenger.
|
||||
|
||||
The absorber is surrounded by a World volume (vacuum)
|
||||
|
||||
A function, and its associated UI command, allows to build a material
|
||||
directly from a single isotope.
|
||||
|
||||
To be identified by the ThermalScattering module, the elements composing a
|
||||
material must have a specific name (see G4NeutronHPThermalScatteringNames.cc)
|
||||
Examples of such materials are build in DetectorConstruction.
|
||||
|
||||
\section Hadr06_s2 PHYSICS LIST
|
||||
|
||||
"Full" set of physics processes are registered, but via PhysicsConstructor
|
||||
objects rather than complete pre-defined G4 physics lists. This alternative
|
||||
way gives more freedom to register physics.
|
||||
|
||||
Physics constructors are either constructors provided in Geant4 (with G4 prefix)
|
||||
or 'local'. They include : HadronElastic, HadronInelastic, IonsInelastic, GammaNuclear,
|
||||
RadioactiveDecay and Electomagnetic.
|
||||
(see geant4/source/physics_lists/constructors)
|
||||
|
||||
HadronElasticPhysicsHP include a model for thermalized neutrons, under the control of a command
|
||||
defined in NeutronHPMesseger.
|
||||
|
||||
GammmaNuclearPhysics is a subset of G4BertiniElectroNuclearBuilder.
|
||||
|
||||
ElectromagneticPhysics is a simplified version of G4EmStandardPhysics.
|
||||
|
||||
Several hadronic physics options are controlled by environment variables.
|
||||
To trigger them, see Hadr06.cc
|
||||
|
||||
\section Hadr06_s3 AN EVENT : THE PRIMARY GENERATOR
|
||||
|
||||
The primary kinematic is a single particle randomly shooted at the
|
||||
centre of the sphere. The type of the particle and its energy are set in
|
||||
PrimaryGeneratorAction (neutron 14 MeV), and can be changed via the G4
|
||||
build-in commands of ParticleGun class (see the macros provided with
|
||||
this example).
|
||||
|
||||
\section Hadr06_s4 PHYSICS
|
||||
|
||||
The program computes and plots energy deposited in the interaction volume
|
||||
(absorber) and the flux of particles leaving this volume.
|
||||
Processes invoked and particles generated during hadronic cascade are listed.
|
||||
|
||||
|
||||
|
||||
\section Hadr06_s5 HISTOGRAMS
|
||||
|
||||
The test contains 23 built-in 1D histograms, which are managed by
|
||||
G4AnalysisManager and its Messenger. The histos can be individually
|
||||
activated with the command :
|
||||
/analysis/h1/set id nbBins valMin valMax unit
|
||||
where unit is the desired unit for the histo (MeV or keV, etc..)
|
||||
(see the macros xxxx.mac).
|
||||
|
||||
1 "total energy deposit"
|
||||
2 "Edep (MeV/mm) profile along radius"
|
||||
3 "total kinetic energy flow"
|
||||
4 "energy spectrum of gamma at creation"
|
||||
5 "energy spectrum of e+- at creation"
|
||||
6 "energy spectrum of neutrons at creation"
|
||||
7 "energy spectrum of protons at creation"
|
||||
8 "energy spectrum of deuterons at creation"
|
||||
9 "energy spectrum of alphas at creation"
|
||||
10 "energy spectrum of all others ions at creation"
|
||||
11 "energy spectrum of all others baryons at creation"
|
||||
12 "energy spectrum of all others mesons at creation"
|
||||
13 "energy spectrum of all others leptons (neutrinos) at creation"
|
||||
14 "energy spectrum of emerging gamma"
|
||||
15 "energy spectrum of emerging e+-"
|
||||
16 "energy spectrum of emerging neutrons"
|
||||
17 "energy spectrum of emerging protons"
|
||||
18 "energy spectrum of emerging deuterons"
|
||||
19 "energy spectrum of emerging alphas"
|
||||
20 "energy spectrum of all others emerging ions"
|
||||
21 "energy spectrum of all others emerging baryons"
|
||||
22 "energy spectrum of all others emerging mesons"
|
||||
23 "energy spectrum of all others emerging leptons (neutrinos)"
|
||||
|
||||
The histograms are managed by the HistoManager class and its Messenger.
|
||||
The histos can be individually activated with the command :
|
||||
\verbatim
|
||||
/analysis/h1/set id nbBins valMin valMax unit
|
||||
\endverbatim
|
||||
where unit is the desired unit for the histo (MeV or keV, deg or mrad, etc..)
|
||||
|
||||
One can control the name of the histograms file with the command:
|
||||
\verbatim
|
||||
/analysis/setFileName name (default Hadr06)
|
||||
\endverbatim
|
||||
It is possible to choose the format of the histogram file : root (default),
|
||||
xml, csv, by using namespace in HistoManager.hh
|
||||
|
||||
It is also possible to print selected histograms on an ascii file:
|
||||
\verbatim
|
||||
/analysis/h1/setAscii id
|
||||
\endverbatim
|
||||
All selected histos will be written on a file name.ascii (default Hadr06)
|
||||
|
||||
\section Hadr06_s6 VISUALIZATION
|
||||
|
||||
The Visualization Manager is set in the main().
|
||||
The initialisation of the drawing is done via the commands
|
||||
/vis/... in the macro vis.mac. To get visualisation:
|
||||
\verbatim
|
||||
> /control/execute vis.mac
|
||||
\endverbatim
|
||||
|
||||
The tracks are drawn at the end of event, and erased at the end of run.
|
||||
gamma green
|
||||
neutron yellow
|
||||
negative particles (e-, ...) red
|
||||
positive particles (e+, ions, ...) blue
