Optical photon simulation

Required geant4 version

• Geant4-10.7 stable version

Install

1. Clone source

git clone https:://github.com/sh-lim/PNU-NPL.git

2. Compile

cd Geant4/Geant4_simulation/Opsim
mkdir build
cd build
cmake ..
make

3. Manage parameter.conf

To manage parameter.conf, link of parameter file is required. and also if you want to make another parameter.conf or want to link , make and link it to the build directory

and linking other macros including vis.mac and run1.mac make easier to manage

cd build
ln -sf ../OpParameter.conf .
ln -sf ../run1.mac .
ln -sf ../vis.mac .

4. Run

You can run this example with simple command.

./Opsim

The default setting of parameter container is "OpParameter.conf" in build directory

5. development log

26.Jan

• applied random number to X,Y and Z of beam starting point with its unit.
• renamed function name 'read,'Print' to 'ReadParameters',"PrintParameter".
• unified the style (int, Int_t, G4int) to G4int.

30.Jan

• checked Random Seed and output
• applying seed at G4sim.cc is effective to PrimaryGeneratorAction
• checked 10000 different outputs of flat distribution of G4UniformRand
• /random/setSeed command in run1.mac was removed because it is not effective

31.Jan

• Opsim.cc: batch mode condition was modified (argc>2 => argc>=2)
• Opsim.cc: time based seed was implemented

02.Feb

• OpRunAction.xx: added container for optical photons
• OpTrackingAction.cc: extract optical photons when it created and died
• OpParameters.conf: added boolean structure for photon output

03.Feb

• OpParameterContainer.xx: moved to standard class to static class
