Project description

The project targets a standalone Geant4 simulation of the dual-readout electromagnetic-sized calorimeter 2023 test beam at the CERN-SPS H8 beam line.

Available datasets and analyses

• To be added.

How to

Build, compile and execute on Mac/Linux

1. git clone the repo

   git clone https://github.com/DRCalo/DRTB23Sim.git

2. source Geant4 env

   source /relative_path_to/geant4-install/bin/geant4.sh

3. cmake build directory and make (example using geant4.10.07_p01)

   mkdir build && cd build
   cmake -DGeant4_DIR=/absolute_path_to/geant4.10.07_p01-install/lib/Geant4-10.7.1/ relative_path_to/DRTB23Sim/
   make

4. execute (example with DRTB23Sim_run.mac macro card, 2 thread, FTFP_BERT physics list, no optical propagation, and no vertical rotation of the calorimeter)

   ./DRTB23Sim -m DRTB23Sim_run.mac -t 2 -pl FTFP_BERT -opt false -vert false

Parser options

• -m macro.mac: pass a Geant4 macro card
• -t integer: pass number of threads for multi-thread execution (example -t 3, default t 2)
• -pl Physics_List: select Geant4 physics list (example -pl FTFP_BERT)
• -opt FullOptic: boolean variable to switch on (true) the optical photon propagation in fibers (example -opt true, default false)
• -vert VertRot: boolean to switch on (true) vertical rotation of the calorimeter (example -vert true, default false)

Build, compile and execute on lxplus

1. git clone the repo

   git clone https://github.com/DRCalo/DRTB23Sim.git

2. cmake, build directory and make (example using geant4.10.07_p01, check for gcc and cmake dependencies for other versions)

   mkdir build && cd DREMTubes-build
   source /cvmfs/sft.cern.ch/lcg/contrib/gcc/8.3.0/x86_64-centos7/setup.sh 
   source /cvmfs/geant4.cern.ch/geant4/10.7.p01/x86_64-centos7-gcc8-optdeb-MT/CMake-setup.sh 
   export CXX=`which g++`
   export CC=`which gcc`
   cmake3 -DGeant4_DIR=/cvmfs/geant4.cern.ch/geant4/10.7.p01/x86_64-centos7-gcc8-optdeb-MT/lib64/Geant4-10.7.1 ../DRTB23Sim/
   make

3. execute (example with DRTB23Sim_run.mac macro card, 2 threads and FTFP_BERT physics list)

   ./DRTB23Sim -m DRTB23Sim_run.mac -t 2 -pl FTFP_BERT

My quick Geant4 installation

Here is my standard Geant4 installation (example with Geant4.10.7.p01) starting from the unpacked geant4.10.07.tar.gz file under the example path "path/to".

1. create build directory alongside source files

   cd /path/to
   mkdir geant4.10.07-build
   cd geant4.10.07-build

2. link libraries with CMAKE (example with my favourite libraries)

   cmake -DCMAKE_INSTALL_PREFIX=/Users/lorenzo/myG4/geant4.10.07_p01-install \
   -DGEANT4_INSTALL_DATA=ON -DGEANT4_USE_QT=ON -DGEANT4_BUILD_MULTITHREADED=ON \
   -DGEANT4_USE_GDML=ON ../geant4.10.07.p01

3. make it (using N threads, e.g. -j 4)

   make -jN
   make install
