Purpose

IMPORTANT : this web page is no more active. Both "Low Energy" and "Standard" electromagnetic physics working groups of the Geant4 collaboration have been merged into a single "Electromagnetic Physics" working group from June 2019. 

The Geant4 Low Energy Electromagnetic Physics Working Group develops and maintains sets of processes and models to describe the electromagnetic interactions of photons, electrons, positrons, hadrons and ions with matter down to very low energies (eV scale), including the Geant4-DNA project, initiated by the European Space Agency.

Applications of such processes and models range from high energy physics to space science and bio-medical applications.

These activities take place in full collaboration with the Standard Electromagnetic Physics Working Group of the Geant4 collaboration.

What is new in Geant4 10.5 ?

Overview of our most recent developments.

Useful information

• Catalog of Geant4 low energy electromagnetic physics processes and models:
  • Livermore models for gamma and electrons
  • Penelope models for gamma, electrons and positrons
  • Elastic models for gamma (JAEA)

Publications

See our main publications listed on the Geant4@IN2P3 publications page and on the Geant4 publications page.

Geant4 Virtual Machine

• Geant4 for VMware and VirtualBox is a link to a free and ready-to-use software suite allowing you to run entirely Geant4 (a so-called Geant4 Virtual Machine) and associated tools on a Windows PC or Mac under the VMware or VirtualBox software without the need for Geant4 installation. 
• Follow us on Geant4VM on Twitter for updates of this virtual machine.
