Tutorial on Geant4 for users interested to begin or improve their usage of Geant4. Appropriate for creating applications in any domain, with emphasis on topics most relevant to experiments in High Energy or Nuclear Physics. This is a hands-on tutorial course based on Geant4 version 10.6.

Lectures will cover all aspects of Geant4 from the basic building blocks of Geant4 through intermediate topics, interspersed with examples that build a progressively more complex application extensible to real use.

The course is expected to be of interest to novices and those with basic or partial familiarity with Geant4. Participants are expected to have a reasonable knowledge of C++.


The cost for the course is 100 CHF. Pre-registration is required as capacity is limited. The course was created for users with CERN affiliation (experiment or other), who can register via the Learning Hub

A limited number of places is expected to be available for 'external' Geant4 users to register, after December 7th.  Please note that if you have requested a place in the course your registration will only be  complete after you have paid the course fee.

Laptop and Preinstallation of Geant4 are Required

Users must bring a laptop capable of running Geant4, equipped with a wireless internet connection. CERN will not offer any computers for tutorial participants. Minimum required free disk space to install the Geant4 Virtual Machine is about 25 GB; the recommended amount of RAM is 2 GB or over.

Participants are expected to arrive with a working installation of Geant4. At the start of the tutorial there will be an exercise that serves as a basic check the installation of Geant4 and related libraries, to ensure that it is working adequately and to attempt to correct minor difficulties.

We require the use of the Geant4 Virtual Machine (see instructions) as the baseline installation of Geant4. Users must have this installed on their machine, to ensure that they can undertake the exercises in an environment which supports all necessary functionality.

An additional, alternative installation can be created by users, with native compilers. Supported systems and C++ compilers for this are listed in the Geant4 Installation Guide. If you have questions about whether your laptop is appropriate, or problems about installing Geant4, see the Geant4 Installation Guide, and/or the Geant4 Installation and Configuration Discussion Forum.
