calvision's Introduction

Calvision

GEANT4-based simulation of energy deposition in a large crystal.

Installing

On UMD T3 cluster:

source g4env.sh
cmake -DGeant4_DIR=/cvmfs/geant4.cern.ch/geant4/10.5/x86_64-slc6-gcc63-opt/lib64/GEANT4-10.5.0
cmake --build .

Events running

For the interactive runing: Check the geometry through a detector viewing window

./Calo -c template.cfg -u Xm

-c template.cfg is the config file mainly for the DetectorConstruction

-m run.mac is the macro file for the initialization of G4GeneralParticleSource

-o test mean the results will be saved as test.root

Simulations can be run in this way:

./CEPC_CaloTiming -c template.cfg -m run.mac -o test

Tools

plot_Eion.C in the ./tool directory can be used to generate (1) fraction of ionizing enegry vs. partcile velocity for different particles and (2) number of inelastic interactions vs. proton ionizing energy deposition.

You only need to change the root file in this line:

TFile *ffile = new TFile("test.root");

Other files in ./tool are used to help generating condor files for massive simulations. Do:

source generate_temp.sh

it will generate files for job submission.

Then do source submit_condor.sh to submit jobs.

The line getenv=True in temp_jdl.sh sets the batch environment the same as current environment. So don't forget to do source g4env.sh before you try to submit jobs.

More Branches could be added in CreateTree.cc and filled in SteppingAction.cc.
