Geant4 general particle source manual

The Physics Reference Manual provides detailed explanations of the physics implemented in the Geant4 toolkit. The manual’s purpose is threefold: •to present the theoretical formulation, model, or parameterization of the physics interactions included in Geant4. GEANT4 is a toolkit for both full and fast Monte Carlo simulation of detectors in High Energy Physics. It is also designed to take into account the requirements of space and cosmic ray applications, nuclear, heavy ion and radiation computations, and medical applications. The following document gives you a more complete introduction to Geant4. General Particle Source G4GeneralParticleSource is another concrete implementation of G4VPrimaryGenerator Primary vertex is randomly chosen on surface of a given volume – useful for radioactive sources – pre-defined energy spectra (power law, etc.) available Capable of event biasing (variance reduction) – can enhance certain particle types.

specifies that the emission must be confined to a volume of the Geant4 geometry. In this case, the emission distribution is the intersection of the General Particle Source (GPS) and the Geant4 volume. The Geant4 volume must be specified by its physical volume name: GATEname + ‘_phys’. Several terms used throughout the Physics Reference Manual have specific meaning within Geant4, but are not well-defined in general usage. The definitions of these terms are given here. • process - a C++ class which describes how and when a specific kind of physical interaction takes place along a particle track. Emilio Mendoza Cembranos –Daniel Cano Ott CIEMAT - ENSAR2 workshop –April Introduction. Geant4 allows to use the information available in ENDF-6format data libraries for the transport of low energy neutrons (up to 20 MeV) and charged particles (up to MeV), using the G4ParticleHPpackage. Originally this package was written for neutrons (G4NeutronHP), but it has been extended protons, deuterons, tritons, 3He, alphas.

In this case, the emission distribution is the intersection of the General Particle Source (GPS) and the Geant4 volume. The Geant4 volume must be specified.
