TestEm4
|
|
-------
|
|
|
|
This example has been setup to test the low energy gamma processes.
|
|
|
|
1- GEOMETRY DEFINITION
|
|
|
|
It is a cylinder of 5 cm radius filled with C6F6.
|
|
|
|
2- PHYSICS LIST
|
|
|
|
The particle list contains only gamma, electron,positron.
|
|
The physics list contains the 'standard' electromagnetic processes.
|
|
|
|
3- AN EVENT : THE PRIMARY GENERATOR
|
|
|
|
The primary kinematic is a single 9 MeV gamma randomly shooted at the
|
|
middle of the cylinder.
|
|
|
|
4- VISUALIZATION
|
|
|
|
The Visualization Manager is set in the main().
|
|
The initialisation of the drawing is done via the command
|
|
/vis~/create_view in the macro init.mac. This macro is
|
|
automatically read from the main in case of interactive running mode.
|
|
|
|
The detector has a default view which is a transversal view of the
|
|
cylinder.
|
|
|
|
The tracks are drawn at the end of event, and erased at the end of run.
|
|
Optionaly one can choose to draw all particles, only the charged one,
|
|
or none. This command is defined in EventActionMessenger class.
|
|
|
|
5- PHYSICS SURVEY
|
|
|
|
the energy deposited in C6F6 is histogramed (HEP Hist)
|
|
|
|
6- HOW TO START ?
|
|
|
|
- compile and link to generate an executable
|
|
% cd examples/extended/electromagnetic/TestEm4
|
|
% gmake
|
|
|
|
- execute TestEm4 in 'batch' mode from macro files
|
|
% TestEm4 run01.mac
|
|
|
|
- execute TestEm4 in 'interactive mode' with visualization
|
|
% TestEm4
|
|
....
|
|
Idle> type your commands
|
|
....
|
|
Idle> exit
|
|
|
|
- visualize the histogram
|
