Software/Geant4

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.

This is a tutorial about applications of GEANT4 to medical physics. 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.

Running Geant4 Simulations

In order to run Geant4 simulations, you will either need to download and install the software yourself or make use of the existing installation on the UCL HEP Linux cluster.

In order to use the UCL HEP Linux cluster, you will need a HEP account: please contact Dr. Simon Jolly for more details.

For more information on using Geant4 on the HEP Linux cluster, see the UCL HEP Linux Cluster page.

In order to install your own version of Geant4, you will need to download and compile the course code from the CERN Geant4 website.

Extensive instructions have been put together describing how to compile the code yourself. The best place to start is the Geant4 Installation page.

• Downloading the Geant4 package
• Linux terminal
• Installing Geant4
• Updating Geant4
• Running an example

Tutorials

A number of tutorials are available to help you get started running your own simulations. It is recommended that novice users make use of these simulations as templates to construct their own.

There are two sets of tutorials available to help you getting started in running simulations with Geant4:

• The Basic Tutorials introduce the rudiments of Geant4 for proton therapy simulations: these are described in more detail on the Basic Tutorials page.
• The Advanced Tutorials describe more sophisticated proton therapy simulations in Geant4: more information can be found on the Advanced Tutorials page.

Data Analysis Software

These tutorials use ROOT to analyse data. Useful links:
