From UCL HEP PBT Wiki
This is a tutorial about applications of GEANT4 to medical physics. The GEANT4 is installed on the HEP Linux cluster at UCL. You will need an account on that cluster to be able to use this software, run example tutorials and create your own applications.
Accounts and Discussion forum
- Getting a computing account
Apply for a computing account on the HEP Linux cluster by sending e-mail to HEPComputingSupport. In your e-mail you have to state the reason for your application (e.g. medical physics student who will use GEANT4 on the HEP cluster).
You will receive an e-mail from the HEP computing support with your username and password. Now you can log in to the HEP cluster plus1 via ssh email@example.com. Your personal area on plus1 cluster will be at /home/username/.
- Discussion about the tutorials
You can write to the discussion forum by clicking the discussion tab at the top of the page.
The basics of GEANT4
GEANT4 is a toolkit for simulating the passage of particles through matter. You can use GEANT4 by creating your own simulation applications using the available GEANT4 tools.
- Introduction to GEANT4 will help you understand the basics of GEANT4 and the necessary ingredients to write your own application.

Data analysis software
These tutorials use ROOT to analyse data. Useful links:
Similarly, data can be analysed using MATLAB. This is a link to interactive introduction to MATLAB:
This section includes several basic tutorials:
- Monoenergetic photon pencil beam is a simple code which shows the dose deposition in water along the incident monoenergetic photon beam.
- Monoenergetic proton pencil beam is a simple code which shows the dose deposition in water along the incident monoenergetic proton beam.
- Proton beam with realistic geometry is a simple code with realistic geometry of the proton beam. The primary particles are generated with initial energy, position and direction described by Gaussian distributions. Computed is the dose deposition in water along the beam.
- Several proton beams with spread out Bragg peaks is a simple code which shows the dose deposition in water from several incident monoenergetic proton beams.
- Electron beam using phase-space files is a simple code which shows the dose deposition in water along the incident electron beam using phase-space data files.
