SiPM Detector simulation using CERN Geant4

Description

Simulation of detecting photons using Silicon photomultiplier. The output file is a ROOT file. Can be checked by TBrowser.

Prerequisities

CERN Geant4
CERN Root (tested on 6.19/01)
Linux or MacOS (should work on Windows, not tested)
Also tested on WLS Ubuntu (X11 (for e.g. VcXsrv) and OpenGL needed)

Building

Before building, be sure that you changed the macroPath to the right directory in sipm.cc.

git clone https://git.divaldo.hu/divaldo/SiPM.git
mkdir build_dir && cd build_dir
cmake ../SiPM
make -jN (where N is the number of jobs to run simultaneously)

Running

Run with default parameters (not always works)

./sipm

Run with default config file (config.conf)

./sipm -df

Run with custom config file

./sipm -f config_file_name.conf

Config file parameters

Small changes according to the new parameters

2020-02-06

SiPMAnalisys' and SiPMParameters' GetInstance functions are returning a static reference instead of pointer
G4Mutex replaced with std::mutex
Input config file and output data file name can be changed with the GetInstance functions on the first call
