Simulation of AmBe emergent gammas (based on emergent gammas simulation code for AmLi by J. Busenitz and R. Sazzad).
Prerequisite: Geant 4.10.04.p02 and ROOT 5.34/07 (later versions are ok)

- Download and unpack the AmBe_emergent_gammas.tar.gz archive, e.g. run
in Linux terminal
"tar -xf AmBe_emergent_gammas.tar.gz" - Source setup scripts for Geant4, e.g.
source /usr/local/geant4.10.04.p02/bin/geant4.sh
source /usr/local/geant4.10.04.p02/share/Geant4-10.4.2/geant4make/geant4make.sh- Go to the AmBe_emergent_gammas folder and run "cmake -DGeant4_DIR=/path/to/local/geant4VersionInstalled/lib64/Geant4.xxxx/ path/to/extracted/source/directory", e.g.
cmake -DGeant4_DIR=/usr/local/geant4.10.04.p02/lib64/Geant4-10.4.2/ .- Compile with
make(it will create an executable named "capsule_emissionV2") - Prepare an HEPEvt format generator file for AmBe gamma spectrum (from
am241be.spectrum) which will be read by capsule_emissionV2:- make an executable of am241be.cc, e.g. run
g++ am241be.cc -o am241be.exe
- run the executable with the number of events to be generated and the output file name "generator.data", e.g.
./am241be.exe 10000000 > generator.data
- make an executable of am241be.cc, e.g. run
- The simulations can be executed by running
./capsule_emissionV2 AmBe.mac- The output root file "outcapsule.root" containing energy distributions of primary and detected gammas will be generated within the same folder (the filename and path can be changed in src/ExN03RunAction.cc file).
- If you didn't comment out the visualization options in AmBe.mac, it will generate .wrl file in the same folder.
- Example .wrl files which visualize the geometry is contained within "geometry_vis_example" subfolder
