Introduction

This example shows the dose distribution in water along the incident photon beam. The beam hits the water cube surface and deposits a dose under the surface of the water. The volume of the water cube is divided into voxels. At each voxel the dose contribution from the pencil beams is summed up and yields the total dose along the beam axis.

Setting up the environment

Connect to HEP cluster and create folder PhotonPencilBeam in your area

ssh username@plus1.hep.ucl.ac.uk
cd /home/username/
mkdir PhotonPencilBeam
cd PhotonPencilBeam

Setup GEANT4 environment

source GEANT4 script

How to get the code

Copy the code to your area

cp -r /unix/pbt/tutorials/basic/PhotonPencilBeam_source /username/PhotonPencilBeam/

• How to run the code

Inside /username/PhotonPencilBeam/ create directory

mkdir PhotonPencilBeam_build

Change to this directory and run cmake and make to build the PhotonPencilBeam tutorial

cd PhotonPencilBeam_build
cmake -DGeant4_DIR=/unix/pbt/Software/..../ /username/PhotonPencilBeam_source/
make
