== 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 <blockquote> <span style="color:#800000"> ssh username@plus1.hep.ucl.ac.uk </span> <br/> <span style="color:#800000"> cd /home/username/ </span> <br/> <span style="color:#800000"> mkdir PhotonPencilBeam </span> <br/> <span style="color:#800000"> cd PhotonPencilBeam </span> </blockquote> ; Setup GEANT4 environment <blockquote> <span style="color:#800000"> source bla.sh </span> </blockquote> == How to get the code == ; Copy the code to your area <blockquote> <span style="color:#800000"> cp -r /unix/pbt/tutorials/basic/PhotonPencilBeam_source /username/PhotonPencilBeam/ </span> </blockquote> == How to run the code == ; Inside /username/PhotonPencilBeam/ create directory <blockquote> <span style="color:#800000"> mkdir PhotonPencilBeam_build </span> </blockquote> ; Change to this directory and run cmake and make to build the PhotonPencilBeam tutorial <blockquote> <span style="color:#800000"> cd PhotonPencilBeam_build </span> <br/> <span style="color:#800000"> cmake -DGeant4_DIR=/unix/pbt/Software/..../ /username/PhotonPencilBeam_source/ </span> <br/> <span style="color:#800000"> make </span> </blockquote> == How to analyze data ==
