15 Examples in the physicslist category show the possible ways how to define
16 a physics list from Geant4 physics constructors. This example demonstrates
17 the usage of G4GenericPhysicsList to build the concrete physics list at
18 the run time.
19
20 In Geant4 versions < 10.4, the generic physics list was demonstrated in the
21 extended/hadronic/Hadr05 example.
22
23 The G4GenericPhysicsList class allows to build the physics list at the run
24 time in two possible ways, either by processing a macro file
25 containing the 'physics list' or by passing a vector of 'physics
26 constructors' names to the constructor of the class.
27
28 To run the example you can call
29
30 ./genericPL -m run.mac [ -p FTFP_BERT.mac ]
31
32 where FTFP_BERT.mac is the macro file containing the 'physics list'.
33
34 If you run this example by calling
35
36 ./genericPL -m run.mac
37
38 the physics list will be constructed by using a vector of the names of
39 the different physics constructor defined in the genericPL.cc file.
40
41 The same experimental setup is used for all examples in the physicslist category:
42
43 1- Detector description
44 -----------------------
45
46 The geometry (defined in the DetectorConstruction class) consists in a box of scintillator material (CsI) followed by a thin box of air (screen) which is used to simplify scoring.
47
48
49 2- Primary generator
50 --------------------
51
52 The primary generator is defined with usage of G4ParticleGun.
53 The default particle is proton which hits the box perpendicular to the input face.
54 The type of the particle and its energy are set in the PrimaryGeneratorAction class, and can
55 be changed via the G4 built-in commands of the G4ParticleGun class.
56
57
58 3- Scoring (ntuples)
59 --------------------
60
61 The screen volume is associated with a sensitive detector, ScreenSD,
62 which accounts the following particle properties:
63 - trackID
64 - particle PDG encoding
65 - particle kinetic energy
66 - particle X,Y position
67 - particle time
68
69 The scored quantities are filled in the Screen ntuple, which is defined using G4AnalysisManager
70 in RunAction class. The ntuple is saved in a Root file, which name is set to be equal to the
71 example name in main () function.
72
73 4- How to build
74 ----------------
75
76 An additional step is needed when building the example with GNUmake
77 due to using the extra shared directory:
78 % cd path_to_example/example
79 % gmake setup
80 % gmake
81
82 This will copy the files from shared in the example include and src;
83 to remove these files:
84 % gmake clean_setup
85
