GeSOS Geant4 software

GEANT4 software to simulate interaction of X rays with setup containing a HPGe Ge detector.

It can simulate four different setups that will be used to study interactions of x-rays in different configurations.

Compilation in SUMO

In order to compile the software you need to charge root and Geant4(v4.11). In SUMO you need to do:

## Modules:
module load physics/geant4/4.11
module load tools/gcc/9.2.0
## Environment variables for Geant4 and ROOT.
export GEANT4=/usr/local/applications/physics/geant4/4.11/
export ROOT6=/usr/local/applications/tools/root6/
export BOOST=/usr/local/applications/tools/boost/1.78
## Geant4 and ROOT environment variables are loaded.
source $GEANT4/bin/geant4.sh
source $ROOT6/bin/thisroot.sh
## libraries. Not sure if this line is realle needed, but include it, just in case
export LD_LIBRARY_PATH=$BOOST/lib:$LD_LIBRARY_PATH:$ROOT6/lib:$GEANT4/lib64:/usr/lib64/:/usr/lib

It's recommended to copy these instruction is a setup_geant4.sh file and then just call source setup_geant4.sh when you start a new session in sumo

Then clone the repository in your local machine Then once the software is in your local repository, cd your_repository and follow these intructions

1. create a build folder: mkdir build (if the folder exist you should clean it, cd build, rm -rf *)
2. cmake ../ or replace ../ by the location of the software
3. make This should create the GeSOS executable. Then to run it in interactive mode, just do inside build: ./GeSOS

Compilation in TOPAZE

In order to compile the software in topaze you just need to copy the repository to topaze and charge root and Geant4(v4.11). In TOPAZE you need to do:

# SOLEIL bashrc
source /ccc/cont003/home/solcomm/solcomm/etc/.bashrc_soleil

# ROOT6
module load soleil/topaze/root6
source $ROOT6/bin/thisroot.sh

# GEANT4
module load soleil/topaze/geant4
source $GEANT4/bin/geant4.sh

It's recommended to copy these instruction is a setup_geant4.sh file and then just call source setup_geant4.sh when you start a new session in topaze

Then copy to topaze the repository with the source code using scp. Once the software is in your local repository, cd your_repository and follow these intructions

1. create a build folder: mkdir build (if the folder exist you should clean it, cd build, rm -rf *)
2. cmake ../ or replace ../ by the location of the software
3. make This should create the GeSOS executable. Then to run it in interactive mode, just do inside build: ./GeSOS

Simulation setup

Select the setup that you want to simulate with:

/GeSOS/det/setDetectorType 1 Options are:

setup 0 consist of Ge detector without collimator for direct x-ray beam radiation: /GeSOS/det/setDetectorType 0

setup 1 consist of Ge detector with collimator for direct x-ray beam radiation: /GeSOS/det/setDetectorType 1

setup 2 consist of Ge detector without collimator plus a sample for direct x-ray beam on sample: /GeSOS/det/setDetectorType 2

setup 3 consist of Ge detector with collimator plus a sample for direct x-ray beam on sample: /GeSOS/det/setDetectorType 3

setup 4 consist of Ge detector with small collimator plus a sample for direct x-ray beam on sample: /GeSOS/det/setDetectorType 4

setup 5 consist of SAMBA Ge detector geometry including collimator for direct x-ray beam radiation: /GeSOS/det/setDetectorType 5

setup 6 consist of SAMBA Ge detector geometry including collimator + a saple for direct x-ray beam on sample: /GeSOS/det/setDetectorType 6

Once you have selected the type of setup that you want to simulate you can also choose the material and thicknees of the collimator (if any), etc

An example of config file my_setup.mac is hte following

/process/em/fluo true
/process/em/auger true
/process/em/augerCascade true
/process/em/pixe true
