Abstract:
Geant4 is an open source software toolkit for simulating the passage of high energy particles into matter and interacting with it. It covers particle energy range from O(100 eV) to multi-TeV, and has some very low energy modules for microdosimetry down to O(eV) and phonon transport (O(mK)). Its object oriented design allowed it to accommodate such variety of physics cases. In this presentation, we will give an overview of the software and its history. We will present applications from various domains which exploit Geant4 : HEP and nuclear science of course, but also space, medical and homeland security. We will mention some perspectives too and in particular the challenges that the HL-LHC poses to Geant4.
Short Bio Marc Verderi
Marc Verderi is a physicist at LLR, Ecole polytechnique, Palaiseau France (CNRS/in2p3). He started in Geant4 by the beginning of the project (1994 = RD44) that he joined in 1995. He has been the deputy spokesperson from 2010 to 2020, while the spokesperson was Makoto ASAI (SLAC, now JLab). Marc has been appointed spokesperson since April 2020. In parallel to Geant4 activities, Marc is working on an ultra-thin beam monitor (10 µm Water Equivalent) for proton/ion therapy since 2014.
