Geant4 Monte Carlo simulation
First, install Geant4 in your machine. Please refer cern webpage (http://geant4.web.cern.ch/geant4/) in order to install Geant4.
The latest version of HKS/HES Geant4 source file and magnetic field data which is calculated by TOSCA is put on the SVN repository. Checkout these files (here I assume your directory name as "~/E05115").
$ls ~/E05115 HES/ HKS/ param/
"HES" ("HKS") contains HES (HKS) Geant4 source files and "param" contains magnetic field maps by TOSCA.
Compile and Run
Under the "HES" directory, you can find following directories and files.
$ls HES GNUmakefile HES.cc gen/ include/ run/ src/
If you have already set up your environment variables, just type "make" under the "HES" directory.
$ cd HES $ make
If compilation finished successfully, you will find executable "HES" under $(G4WORKDIR)/bin/ directory.
$ ls $(G4WORKDIR)/bin/ HES*
Now you can execute the simulation. But before execution, You should do three things.
First, add $(G4WORKDIR)/bin/ directory to $PATH.
Secondly, make a symbolic link to the "~/E05115/param" directory from "run" directory.
$ cd run $ ln -s ~/E05115/param
Finally, make the "ana" directory under the "HES" directory.
$ cd ~/E05115/HES/ $ mkdir ana
Then, go to the "run" directory and type following.
$ cd ~/E05115/HES/run $ HES macro/gun.mac input/sample.in
If everything goes well, you can get data file under the "ana" directory.
$ ls ~/E05115/HES/ana/ sample.root
This is the basic procedure of compilation and execution. If you have some problem about compilation, ask experts.
