AdePT Documentation

This site is the home for AdePT installation, user guide, and API reference.

Introduction

AdePT is a lightweight Geant4 plugin designed to accelerate high-energy physics simulation by offloading electromagnetic transport to GPUs. Currently, it targets electrons, positrons, and gammas.

AdePT relies on G4HepEm, which provides specialized, optimized tracking for electrons, positrons, and gammas. AdePT provides the GPU transport implementation and integrates it with Geant4 applications.
