||
| This example tests the generation of alphas with a well defined energy from a thin foil immersed in a gas volume. | ||
|
|
||
| #### Detector geometry | ||
|
|
||
| The geometry consists of a 10x10x10cm3 box made of Argon gas. In the middle of the box a small copper plate is placed. The thickness of the plate in um can be controlled with an enviromental system variable, REST_FOIL. | ||
|
|
||
| #### Event generator | ||
| The event generator will produce mono-energetic alphas produced in the copper sample volume (physical volume named source). The energy of the alphas can be controled using the REST_ENERGY system environment variable expressed in MeV. | ||
|
|
||
| #### Testing the example | ||
|
|
||
| Create a "data" directory if not existing already | ||
|
|
||
| ``` | ||
| mkdir data | ||
| ``` | ||
|
|
||
| Execute the following to launch the generation of 10,000 alphas. | ||
|
|
||
| ``` | ||
| restG4 alphas.rml | ||
| ``` | ||
|
|
||
| Execute the following to launch the processing of the generated events and produce few observables inside the analysis tree. | ||
|
|
||
| ``` | ||
| restG4 --c analysis.rml --f data/FileGenerated.root | ||
| ``` | ||
|
|
||
| See also `../../.gitlab-ci.yml` and `Validation.C` for validation routines executed in the pipeline. The following plot showing the energy spectrum is generated using the pipeline. | ||
|
|
||
|
|
||
|  | ||
|
|
||
| Commands to reproduce the figure shown follow: | ||
|
|
||
| ``` | ||
| mkdir data | ||
| export REST_ENERGY=5 | ||
| export REST_FOIL=1 | ||
| restG4 alphas.rml | ||
| export REST_FOIL=5 | ||
| restG4 alphas.rml | ||
| export REST_ENERGY=1 | ||
| restG4 alphas.rml | ||
| restManager --c analysis.rml --f Run_1MeV_5um.root | ||
| restManager --c analysis.rml --f Run_5MeV_1um.root | ||
| restManager --c analysis.rml --f Run_5MeV_5um.root | ||
| restManager --c plots.rml --f "data/*g4Ana*root" | ||
| ``` | ||
|
|
||
|
|
||
| A minimal ROOT shell commands to visualize the detector geometry is: | ||
|
|
||
| ``` | ||
| export REST_FOIL=5 | ||
| restRoot | ||
| root [0] TRestGDMLParser *g = new TRestGDMLParser() | ||
| root [1] TGeoManager *geo = g->GetGeoManager("geometry/setup.gdml") | ||
| root [2] geo->GetTopVolume()->Draw("ogl") | ||
| ``` | ||
|
|
||
|  | ||
|
|
||
| Minimal ROOT shell commands to visualize events | ||
|
|
||
| ``` | ||
| restRootMacros | ||
| root [0] REST_Geant4_ViewEvent("data/Run_5MeV_1um.root") | ||
| root [1] TGeoManager *geo = g->GetGeoManager("geometry/setup.gdml") | ||
| root [2] geo->GetTopVolume()->Draw("ogl") | ||
| ``` | ||
