The simulation framework

The FOOT simulation is performed using the FLUKA software package.

Running the simulation: how to

There are several steps needed to get, compile, run, access the simulation output.

Getting the code

The instructions to download the code are available in the FOOT software page.

Compiling and running

As a prerequisite for running a simulation you need a valid installation of the FLUKA software.

You have to setup the $FLUPRO, $FLUTIL and $FLUFOR variables before compiling the code (help with the FLUKA installation phase is provided in the FLUKA web page, FLUKA mailing lists and, if everything else failed, from the FOOT FLUKA "experts": V. Patera, G. Battistoni, A. Sarti). Once everything is installed and setup, you can proceed with the following instructions.

To compile the code you have to:

• Go in the Simulation folder.
• Source the link_FOOTpro.sh script.
• After the code is compiled, check that you have a fluka_FOOT.exe executable created in your Simulation folder.

• Go in the Simulation folder.
• Execute the command:

$FLUPRO/flutil/rfluka -e fluka_FOOT.exe -N0 -M1 FOOT_EMFon

• The output will appear in:

Decoding the output

The output format is a dat file. To have access to a tupled file you need to convert it using a converter.

Libraries are kept under TXT2ROOT folder.

• Compile the converter in TXT2ROOT by issuing the command:

make

• Then you can run the converter with the following command:

./Txt2Root -in ../FOOT_new001_TXT.dat -out FOOT_new001_TXT.root

This will generate the output.root file containing all the MC info needed for furher processing.

Event reconstruction

The reconstruction of the decoded MC events is accomplished using the reconstruction software documented in the related web page.
