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 10.7.

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++.


Registration is now FULL ( in addition the waiting list for the course is also FULL ).

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 available for 'external' Geant4 users to register.  Please note that if you require an invoice, you must request it before you complete payment.

Your registration will only be complete after you have paid the course fee.

Preinstallation of Geant4 is Required

Users must setup a desktop or laptop capable of running Geant4, equipped with an internet connection. 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 be equipped with a working installation of Geant4. A dedicated virtual session will be organised to exercise the remote connection and to check the installation of Geant4 and related libraries, to ensure it is working correctly and to address questions or difficulties.

The Geant4 Virtual Machine (see instructions) as the only supported installation of Geant4. Users must have this installed on their machine, so 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 machine is appropriate, or problems about installing Geant4, see the Geant4 Installation Guide, and/or the Geant4 Installation and Configuration Discussion Forum.
