This code is a Geant4 simulation for the WISArD experiment at ISOLDE CERN.
- Geant4 11.1.2
- CLHELP
- ROOT
- PyROOT (only for Analyze.py)
- Environement variables :
source $G4INSTALL/share/Geant4/geant4make/geant4make.csh $G4INSTALL/share/Geant4/geant4make/
setenv PATH ${PATH}:$WhereGitIs/WISArD/bin/Linux-g++- Only 8B, 8Li, 14O, 20Mg, 24Si, 26S and 32Ar at 30 keV can be use in the simulation because there is a SRIM file for them. But you can generate a file for an other nucleus or energy with SRIM. You have to rename a RANGE_3D.txt SRIM file and place it in the SRIM_data folder.
wisard wisard macro.macExemple for 32Ar with 10 threads in Standard Model case
CRADLE-G4 nucleus=32Ar N=10 a=1 b=1or
CRADLE-G4 nucleus=32Ar N=10 CS=0 CV=1 events=1000If one Standard Model parameter is not given it will be set in SM case. Additionaly, macro_base.mac will be use as macro sample. See --help option to see all the options.
You end up a Tree, detectors histograms and simulation paramater in the ROOT TFile generated.
Located at the beginning of the TFile, you can find all the simulation variables chosen.
The Tree is update each 10 000 events and contains :
- Event Number
- Gun Information (particle PDG, position, direction, energy, time)
- Catchers Energy deposit
- Plastic Scintillator (deposit energy, hit position, hit angle, hit time)
- Silicon Detectors (deposit energy, hit position, hit angle, hit time, detector code)
There are 2 for each strip, one for the β-p coincidence and an other one for the anti-coincidence. The β detection threashold is set in the macro file.
A very rapid analysis was made with PyROOT. To use it you have to indicate the filename in the main function.
