## INTRODUCTION
|
||
Example ch1 is an easy demonstration of the minimum requirements necessary
|
||
to integrate the G4ChannelingFastSimModel and the G4BaierKatkov model into a project
|
||
in order to simulate the physics of channeling and
|
||
channeling radiation/coherent bremsstrahlung.
|
||
|
||
This example serves as a guideline for users on how to add this physics
|
||
to their existing Geant4 projects. It includes the minimum necessary options
|
||
to incorporate this physics. Specifically, it requires registering
|
||
G4FastSimulationPhysics in the main routine and
|
||
adding a few lines of code in DetectorConstruction.
|
||
|
||
## DESCRIPTION
|
||
The example is based on the following experiments on channeling [1] and
|
||
channeling radiation [2] in a bent crystal, carried out at Mainz Mikrotron MAMI with
|
||
855 MeV electrons. The experimental validation of G4ChannelingFastSimModel is
|
||
described in [3].
|
||
|
||
This example includes a bent crystal and a detector positioned behind it.
|
||
The incoming beam is set up in macro run.mac.
|
||
|
||
The example does not include any input of the model or geometry parameters
|
||
from the macro to keep it as straightforward as possible. The output is recorded
|
||
into the file results.root. It consists of
|
||
the charged particle distribution at the detector in the x-plane
|
||
(the plane of crystal bending and perpendicular to the crystal planes) as well as
|
||
the spectrum of photons arriving to the detector. To build these plots, one has to
|
||
open this file in root and use
|
||
```cpp
|
||
x_out->Draw()
|
||
```
|
||
|
||
and
|
||
|
||
```cpp
|
||
Spectrum->Draw()
|
||
```
|
||
|
||
for the coordinates and the spectrum, respectively.
