XIII International Geant4 School

27 Jul 2026, 09:00 → 31 Jul 2026, 18:00 Europe/Prague

Welcome to the One-Week School on the Geant4 simulation toolkit

We are delighted to invite you to the One-Week School on the basic Geant4 simulation toolkit to be held at ELI Beamlines facility in Dolní Břežany (CZ) very close to the beautiful city of Prague, from July 27th to 31st, 2026. 

The school is organized jointly by Laboratori Nazionali del Sud of INFN – Istituto Italiano di Fisica Nucleare (Italy), ELI-ERIC in collaboration with COST Action CA21128 PROBONO.

The course is organized as a mixture of theoretical lectures and pratical hands-on sessions.

The registration fee is 350,00 euros, which includes lunches, coffee breaks and daily transportation from/to Prague. Due to the hands-on sessions, the maximum attendance is limited to 50 participants.

Hands-on Geant4 course

Geant4 is a software toolkit, written in C++, for simulating tracking of particles in matter with the Monte Carlo approach. The software is developed and maintained by an international collaboration of scientists belonging to different institutions. Geant4 can be used for applications in high energy physics, astrophysics, medical physics, particle astrophysics and nuclear physics.

The lectures of the XIII International Geant4 School will cover all aspects of the toolkit from basic installation through advanced topics and will be interspersed with examples that build a progressively more complex application, extensible to real space and medical use. The use of Geant4 in a laser-plasma environment will be discussed in a dedicated lecture.

A dedicated short C++/cmake refresher course is also included, to get participants familiar with the basic elements of the Geant4 programming language.

The school is aimed at PhD students, post-docs, and young researchers working at universities or research institutes. On the last day of the School, students will have the opportunity to test their learning achievements through a written exam. The successful outcome of the test will be reported on a written certificate for those interested. A simple attendance certificate will also be available on request.

Virtual Machine and hands-on material:

Participants are recommended to bring their own laptops. A virtual machine with Linux-CentOS and a ready-to-use Geant4 and Python installation will be made available.

The COST Action PROBONO will support a limited number of students. More details can be found here.
