Software/Geant4/Tutorials/Basic/Electron Beam Using Phase-Space Files

Introduction

This example shows the dose distribution in water along the incident electron beam. The volume of the water cube is divided into slices perpendicular to the incident beam. At each slice the deposited dose and energy is computed.

The slices are created using class G4PVReplica. The energy and dose are scored using classes G4UserSteppingAction and G4UserRunAction. The electron beam is generated using Varian Clinac 2100 C/D phase-space data files. You can find more information about phase-space data at the IAEA website. Here you can read more about the Varian Clinac 2100 C/D electron beam. There is an option to chose among several EM physics lists.

How to run the tutorial

Connect to the HEP cluster and create folder ElectronPHSPFolder in your area

ssh -X username@plus1.hep.ucl.ac.uk 

username@plus1.hep.ucl.ac.uk's password: type your password here
 
[username@plus1 ~]$ mkdir ElectronPHSPFolder 

[username@plus1 ~]$ cd ElectronPHSPFolder  

Setup your environment

[username@plus1 ElectronPHSPFolder]$ source /unix/pbt/software/dev/bin/pbt-dev.sh  

Copy the code to your working directory and rename it

[username@plus1 ElectronPHSPFolder]$ cp -r /unix/pbt/tutorials/basic/ElectronPHSP .
  
[username@plus1 ElectronPHSPFolder]$ mv ElectronPHS ElectronPHSP_source

Inside /home/username/ElectronPHSPFolder/ create a directory

[username@plus1 ElectronPHSPFolder]$ mkdir ElectronPHSP_build  

To compile the code enter this directory and run cmake and make

[username@plus1 ElectronPHSPFolder]$ cd ElectronPHSP_build 

[username@plus1 ElectronPHSP_build]$ cmake -DGeant4_DIR=/unix/pbt/software/dev /home/username/ElectronPHSPFolder 
/ElectronPHSP_source 

[username@plus1 ElectronPHSP_build]$ make  

Run macro electron.mac

[username@plus1 ElectronPHSP_build]$ ./electronPHSP electron.mac
