Examples in this directory demonstrate specific hadronic physics simulation with histogramming.
This example demonstrates a usage of G4PhysListFactory to build Physics List and G4HadronicProcessStore to access cross sections.
This example application is based on the application IION developed for simulation of proton or ion beam interaction with a water target. Different aspects of beam target interaction are demonstrating in the example including longitudinal profile of energy deposition, spectra of secondary particles, spectra of particles leaving the target.
This example application is providing simulation of ion beam interaction with different targets. Hadronic aspects of beam target interaction are demonstrated in the example including longitudinal profile of energy deposition, spectra of secondary particles, isotope production spectra.
This example demonstrates how to compute total cross section from the direct evaluation of the mean free path ( see below, item Physics), how to identify nuclear reactions, how to plot energy spectrum of secondary particles.
This example is focused on neutronHP physics, especially neutron transport, including thermal scattering.
Examples of hadronic calorimeters
This example demonstrates survey of energy deposition and particle's flux from a hadronic cascade.
Survey energy deposition and particle's flux from an hadronic cascade. Use PhysicsConstructor objects rather than predefined G4 PhysicsLists. Show how to plot a depth dose profile in a rectangular box.
This example shows how to get "hadronic model per region" using generic biasing: in particular, it is shown how to use "FTFP+INCLXX" in one region, while using the default "FTFP+BERT" in all other regions. Notice that we use the generic biasing machinery, but the actual weights of all tracks remain to the usual value (1.0) as in the normal (unbiased) case.
This example shows how to use Geant4 as a generator for simulating inelastic hadron-nuclear interactions. Notice that the Geant4 run-manager is not used.
This example aims to test the treatment of decays in Geant4. In particular, we want to test the decays of the tau lepton, charmed and bottom hadrons, and the use of pre-assigned decays.
This example demonstrates the Fission Fragment model as used within the neutron_hp model. It will demonstrate the capability for fission product containment by the cladding in a water moderated sub-critical assembly. It could also be further extended to calculate the effective multiplication factor of the subcritical assembly for various loading schemes.
A set of 2 examples, demonstrating how to make use of the interface to FLUKA hadron-nucleus inelastic physics in a G4 application.
The examples are at the process (interaction) level, but a physics list (G4_HP_CernFLUKAHadronInelastic_PhysicsList) is also made available.
The interface to FLUKA itself is also included.
NeutronSource is an example of neutrons production. It illustrates the cooperative work of nuclear reactions and radioactive decay processes. It survey energy deposition and particle's flux. It uses PhysicsConstructor objects.
This example aims to monitor the particle fluence for various particle types and set-ups. The particle fluence at a given position is defined as the average number of particles crossing a unit surface in that position (normalized per one incident primary). The particle fluence is conveniently estimated by summing the particles' track lengths in a thin scoring volume and dividing for the cubic volume of such a scoring volume.
