Channeling effect in Geant4
=================================================================
Enrico Bagli - INFN and University Ferrara (Italy)
bagli@fe.infn.it
This example shows how channeling in bent crystal can be simulated
in Geant4
1.INTRODUCTION
The example simulates the channeling of 400 GeV/c protons in bent
Si crystal. Channeling occurs when particles enter a crystal aligned
with atomic planes or axes. In bent crystals, the particles are
trapped between atomic planes and follow the crystal curvature
being deflected. If the particle direction is tangent to a bent
crystal plane is reflected to the opposite direction with respect
to channeling, i.e., it suffer ‘volume reflection’. The example
provides the physical model for planar channeling and volume
reflection in bent crystals.
2.GEOMETRY
The geometry is a bent Si crystal with three Si detectors placed at
-9.998 m, -0.320 m and 10.756 m with respect to the position of
the bent crystal itself. The Si detectors allows to measure
incoming and outgoing angle after the interaction with the Si bent crystal.
The geometry is all under vacuum.
3.PRIMARY EVENT
The primary events are 400 GeV/c protons launched at -10.5 m from the
crystal with 13.36 microrad x 11.25 microrad divergence.
4.PHYSICS
In the example the physics of channeling and volume reflection
has been added to the standard Geant4 physics. The description
of the used model can be found in the paper ‘A model for the
interaction of high-energy particles in straight and bent
crystals implemented in Geant4’ by E. Bagli et al., available
online at http://arxiv.org/abs/1403.5819
5.EXECUTION & OUTPUT
The executable must be run from within the source directory of the example
to ensure that it can find the path for crystal data files.
Data files for Si crystal interplanar potential, nuclei and electron density
are stored in a subdirectory named ’data’
Upon execution, the 2009_PLB680_129.mac macro will automatically run the
example with 1000 protons.
Use
/xtal/setBR XXX 0. 0. m
To change crystal bending to XXX meters
Use
/xtal/setSize 1.0 70. XXX mm
To change crystal length to XXX millimeter
Use
/xtal/potfilename data/Si220pl
To select the (110) Si crystal plane of channeling
GPS commands are used for the primary generator.
The output is the ExExhCh.root file with the TTree ExExChTree
has the leaves:
- angXin : incoming particle X angle at the crystal
- angYin : incoming particle Y angle at the crystal
- posXin : hitting X position of the particle at the crystal

- angXout: outgoing particle X angle out of the the crystal

Example ch1
-----------
A. Sytov
INFN Ferrara Division, sytov@fe.infn.it
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 x_out->Draw() and Spectrum->Draw() for the coordinates
and the spectrum, respectively.

\section ch2_s1 INTRODUCTION
Example ch2 is an enhanced version of ch1, providing the user with the full functionality of
both the G4ChannelingFastSimModel and G4BaierKatkov, with parameters set up via a macro,
in order to simulate the physics of channeling and channeling radiation/coherent bremsstrahlung.
The example can be exploited for a wide range of cases to study coherent effects in
a straight, bent or periodically bent crystal (crystalline undulator). Channeling
physics in ch2 is active for protons, ions, muons, pions, electrons and their antiparticles.
Any other charged particle can also be activated.
\section ch2_s2 DESCRIPTION
The setup of the example ch2 is identical to ch1. As ch1, this example includes a bent crystal
and a detector positioned behind it. Like ch1, it is based on the 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].
However, since ch2 parameters are fully set up in the macro run.mac, this example
is quite flexible and can be easily adapted for entirely different cases.
A description of all the available options is provided in run.mac.
It includes crystal and detector geometry, activation flags for
G4ChannelingFastSimModel and G4BaierKatkov and various options.
The example also provides detailed descriptions of various options for
G4ChannelingFastSimModel and G4BaierKatkov, which can adjust model parameters
depending on the specific case (see ConstructSDandField in DetectorConstruction).
The front surface of the crystal is placed at z=0 (with z as the beam direction),
while the front position of the detector can be set up via run.mac.
The output is recorded into the file results.root as a set of root ntuples.
These ntuples include:
-# crystal: particles recorded at the crystal entrance,
-# detector: all particles (except photons) recorded at the detector entrance,
-# detector_photons: photons recorded at the detector entrance.
The format of every ntuple includes the following 10 variables (columns):
"eventID", "volume", "x", "y", "angle_x", "angle_y", "Ekin", "particle", "particleID", "parentID"
The variables represent:
-# the event number within the run (column 0),
-# the volume, either the crystal or the detector (column 1),
-# the coordinate (x,y) and the angles (x'=dx/dz, y'=dy/dz) of the impinging particles (columns 2-6),
-# the kinetic energy of the particle (column 7),
-# the particle name (column 8),
-# the particle ID (column 9),
-# the parent ID of the particle (column 10).
To visualize these data, one should either open results.root using root TBrowser or use the python script analysis_ch2.py.

INTRODUCTION
Example ch2 is an enhanced version of ch1, providing the user with the full functionality of
both the G4ChannelingFastSimModel and G4BaierKatkov, with parameters set up via a macro,
in order to simulate the physics of channeling and channeling radiation/coherent bremsstrahlung.
The example can be exploited for a wide range of cases to study coherent effects in
a straight, bent or periodically bent crystal (crystalline undulator). Channeling
physics in ch2 is active for protons, ions, muons, pions, electrons and their antiparticles.
Any other charged particle can also be activated.
DESCRIPTION
The setup of the example ch2 is identical to ch1. As ch1, this example includes a bent crystal
and a detector positioned behind it. Like ch1, it is based on the 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].
However, since ch2 parameters are fully set up in the macro run.mac, this example
is quite flexible and can be easily adapted for entirely different cases.
A description of all the available options is provided in run.mac.
It includes crystal and detector geometry, activation flags for
G4ChannelingFastSimModel and G4BaierKatkov and various options.
The example also provides detailed descriptions of various options for
G4ChannelingFastSimModel and G4BaierKatkov, which can adjust model parameters
depending on the specific case (see ConstructSDandField in DetectorConstruction).
The front surface of the crystal is placed at z=0 (with z as the beam direction),
while the front position of the detector can be set up via run.mac.
The output is recorded into the file results.root as a set of root ntuples.
These ntuples include:
- crystal: particles recorded at the crystal entrance,
- detector: all particles (except photons) recorded at the detector entrance,
- detector_photons: photons recorded at the detector entrance.
The format of every ntuple includes the following 10 variables (columns):
"eventID", "volume", "x", "y", "angle_x", "angle_y", "Ekin", "particle", "particleID", "parentID"
The variables represent:
- the event number within the run (column 0),
- the volume, either the crystal or the detector (column 1),
- the coordinate (x,y) and the angles (x'=dx/dz, y'=dy/dz) of the impinging particles (columns 2-6),
- the kinetic energy of the particle (column 7),
- the particle name (column 8),
- the particle ID (column 9),
- the parent ID of the particle (column 10).
To visualize these data, one should either open results.root using root TBrowser or use the python script analysis_ch2.py.

## INTRODUCTION
Example ch2 is an enhanced version of ch1, providing the user with the full functionality of
both the G4ChannelingFastSimModel and G4BaierKatkov, with parameters set up via a macro,
in order to simulate the physics of channeling and channeling radiation/coherent bremsstrahlung.

## DESCRIPTION
The setup of the example ch2 in run.mac is identical to ch1. As ch1, this example includes a bent crystal
and a detector positioned behind it. Like ch1, it is based on the 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].
However, since ch2 parameters are fully set up in the macro run.mac, this example
is quite flexible and can be easily adapted for entirely different cases.
In addition more specific macros were created to supply users with the setups related to the applications.
These macros partially exploit the model defaults to simplify the example. They include:
-# run_Bent_Crystal_Deflection_Radiation.mac - reduced version (some commands setting defaults deleted) of run.mac but with an identical setup.
-# run_Bent_Crystal_HE_Deflection.mac - an example of particle deflection in a bent crystal at high energies.
-# run_Positron_Source.mac - a simplified example of a positron source within a single W target.
-# run_Radiation.mac - an example of a radiation source in a straight crystal.
A description of all the available options is provided in run.mac and partially in other macros.
It includes crystal and detector geometry, activation flags for
G4ChannelingFastSimModel and G4BaierKatkov and various options.
The example also provides detailed descriptions of various options for
G4ChannelingFastSimModel and G4BaierKatkov, which can adjust model parameters
depending on the specific case (see DetectorConstruction::ConstructSDandField()).
The front surface of the crystal is placed at z=0 (with z as the beam direction),
while the front position of the detector can be set up via run.mac.
The output is recorded into the file results.root as a set of root ntuples.
These ntuples include:
-# crystal: particles recorded at the crystal entrance,
-# detector_primaries: primaries recorded at the detector entrance AND passed through the crystal.
-# detector_photons: photons recorded at the detector entrance produced by primaries passed through the crystal.
-# detector_sedondaries: secondaries recorded at the detector entrance produced by primaries passed through the crystal.
-# missed_crystal: all the particles missed the crystal, however, entering the detector, if any.
The format of every ntuple includes the following 10 variables (columns):
- "eventID", "volume", "x", "y", "angle_x", "angle_y", "Ekin", "particle", "particleID", "parentID"
The variables represent:
-# the event number within the run (column 0),
-# the volume, either the crystal or the detector (column 1),
-# the coordinate (x,y) and the angles (x'=dx/dz, y'=dy/dz) of the impinging particles (columns 2-6),
-# the kinetic energy of the particle (column 7),
-# the particle name (column 8),
-# the particle ID (column 9),
-# the parent ID of the particle (column 10).
For convenience for detector_primaries were added four more variables:
-# the incoming angle x at the crystal entrance,
-# the deflection angle x (the difference between the angle at the detector and the incoming angle),
-# the incoming angle y at the crystal entrance,
-# the deflection angle y (the difference between the angle at the detector and the incoming angle).
These four variables are especially useful for the studies of deflection of primary particles.
To visualize these data, one should either open results.root using root TBrowser or use the python script analysis_ch2.py or its identical version in the jupyter notebook format analysis_ch2.ipynb.
The output data also includes the spectrum of photons using the data produced inside the Baier-Katkov method.
This spectrum requires nearly 2 order on magnitude less data, then the collection of gamma produced in Geant4 as secondaries.
It is very useful especially if the goal is to produce only the spectrum of radiation. This spectrum is normalized on the
total radiation emission probability, which is an equivalent to 1/Nprimaries dN_photon/dE_photon normalization.
Moreover, it is possible to set up a round virtual collimator - an angular selection of photons in the Baier-Katkov method.
This is extremely useful for coherent bremsstrahlung simulation.
CAUTION: though the Baier-Katkov spectrum should identically coincide with the spectrum by secondary photons, sometimes
it may be less accurate, since it is updated only after every setNSmallTrajectorySteps (see run.mac). Moreover,
the virtual collimator does not take into account the transverse positions of particles. Therefore, it is recommended
to use the Baier-Katkov spectrum at low statistics for preliminary researches and optimization while the secondaries produced at
high statistics as a final result.
CAUTION: the angular center of virtual collimator coincides with the global z direction.
The spectrum is produced as a text file, containing the photon energies in the first column and the corresponding spectrum value in the second one.
Note, the bins are not equidistant, they are sampled according to the bremsstrahlung spectrum, with the bin size proportional to 1/E_photon.

=========================================================
Geant4 - an Object-Oriented Toolkit for Simulation in HEP
=========================================================
Example ch3
-----------
A. Sytov
INFN Ferrara Division, sytov@fe.infn.it
INTRODUCTION
Example ch3 demonstrates the minimum requirements necessary to integrate the
G4CoherentPairProduction process into a project, along with the G4ChannelingFastSimModel
and G4BaierKatkov models, to simulate the physics of electromagnetic showers in
an oriented crystal.
The key concept is the acceleration of electromagnetic processes (both radiation and
pair production) in an oriented crystal, which can significantly reduce the effective
radiation length [1,2]. Potential applications include electron/positron sources for
accelerator experiments, as well as crystalline oriented calorimeters for collider and
space applications [1,2].
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 and G4CoherentPairProductionPhysics in the main routine and
adding a few lines of code in DetectorConstruction.
All of this physics does not depend on the physics list. In particular, the
process G4CoherentPairProduction simulates only coherent part of pair production in
the crystal volume, while the incoherent one should be simulated with
standard Geant4 processes.
DESCRIPTION
The example simulates high energy photon interaction (typically above 10 GeV) with
an oriented W crystal with <111> crystal axes aligned along the photon beam direction.
The structure of this example is very similar to the example ch1.
ch3 includes a straight W crystal and a detector positioned behind it.
The incoming photon beam is set up in macro run.mac.
One can also use the Geant4 GUI by launching the code without specifying a macro file.
In this case, the visualization setup is automatically loaded through the vis.mac and
init_vis.mac macro files. The initial beam distribution in this setup will be identical
to that in 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 spectrums of e-, e+
and gamma arriving to the detector. To build these plots, one has to
open this file in root and use Spectrum_electrons->Draw(), Spectrum_positrons->Draw()
and Spectrum_gamma->Draw() for e-, e+ and gamma, respectively.

### INTRODUCTION
Example ch5 is an application for simulating a positron source.
Although the conventional approach based on an **amorphous target** is possible,
the application is primarily designed to simulate positron sources based on oriented crystals.
In the latter case, both the **single-crystal** and the **hybrid scheme**
can be investigated [[1]](#1).
### DESCRIPTION
One or two main volumes can be present in the setup, depending if the user wants to consider
a conventional/single-oriented-crystal scheme [[2]](#2) or the hybrid scheme [[3]](#3).
In the hybrid scheme, the first volume is an oriented crystal (typically along a crystalline axis)
that serves as a radiator, whereas the second volume is a randomly oriented crystal
(equivalent to an amorphous volume) where the photons emitted by the radiator are converted
into positrons.
The converter can be composed of small spheres (the so called _granular target_ - GT)
so as to reduce the energy deposition and the thermomechanical stress.
In addition, from _one to three scoring screens_ are present to score the particles
leaving or enetering the aformentioned volumes. In particular the scoring screen identified
with number 2 is positioned just downstram of the radiator, while scoring screens 0 and 1
are positioned just upstream and downstream of the converter, respectively.
In a conventional or a single crystal scheme, only the scoring screen 0 is present
and it is automatically positioned just downstream of the single volume positioned.
An **advanced hybrid scheme that includes an ideal bending magnet or a collimator**
to remove the charged particle or limit the number of particles impinging on the converter,
respectively, **can also be considered** [[1]](#1).
Through a set of custom macro commands, the user can define the geometry ad the scoring strategy.
A description of all the available options is provided in _run.mac_ (inside the macros folder).
As an example, the Orientetional Coherent (OC) effects (including radiation) in crystals
(enabled by G4ChannelingFastSimModel), which by deafult are activated, can be deactivated
through the command: `/crystal/setOCeffects false`.
The back surface of the radiator crystal is placed at z=0 (with z as the beam direction),
while the front position of the possible converter can be set up via macro.
Various macros are available to simulate different configurations: run_conventional.mac,
run_single_crystal.mac, run_hybrid.mac, and run_hybrid_granular_target.mac
for a conventional, single oriented crystal and hybrid with solid or granular target,
respectively. The parameters set in these macros come from the study carried out for
the positron source of FCC-ee [[2]](#2).
However, they can be changed to investigate different cases.
The output is recorded into a root file whose name can be set by macro
(default is output/output.root), as a set of ntuples.
The ntuple "scoring_ntuple" is used to score the features of the particles impinging
on the scoring screens. It contains the following variables (columns):
"screenID", "particle", "x", "y", "px", "py", "pz", "t", "eventID"
which represents:
- the screen ID (column 0),
- the particle name (column 1),
- the impinging x,y coordinates in mm (columns 2,3),
- the momentum components (MeV) of the particle (columns 4-6),
- the time of arrival of the particle in ns (column 7),
- the event ID (column 9).
The ntuple "edep_rad" and "edep_conv" are used to store the energy deposited (MeV)
in radiator and converter, respectively, thus they contain simply the variables:
"edep", "eventID"
The ntuple "edep_spheres" is instead used to store the energy deposited (MeV) inside the spheres
of a granular target/converter. It contains the variables:
"volumeID", "edep", "eventID"
where volumeID identify the single sphere inside the target. This ntuple is filled only if the
target is indeed granular (it can be activated through the command /det/setGranularConverter true).
Finally, the ntuple "scoring_ntuple2" is used to score the features of the particles leaving
the radiator or the target/converter. It contains the following variables (columns):
"particle", "x", "y", "z", "px", "py", "pz", "t", "eventID", "trackID"
which represents:
- the particle name (column 0),
- the impinging x,y,z coordinates in mm (columns 1-3),
- the momentum components (MeV) of the particle (columns 4-6),
- the time of arrival of the particle in ns (column 7),
- the event ID (column 8),
- the track ID (column 9).
The three-dimensional distributions of energy deposition in the converter
(radiator if the converter is not present) can be scored through the standard
box mesh scorer defined in the attached macros.
To visualize these data one should use the python notebook analysis_ch5.ipynb.
Once the example is build, an interactive session with the graphic user intergace (GUI)
showing a defualt geometry set through macro geom.mac can be run by simply typing
`./ch5` in a terminal after moving inside the build directory.
