Parameters. matlist type s Omittable : default value = all Geant4 Materials Tutorial Daniel Brandt, 04 April 2012 Single Element Materials Need G4Material* in order to instantiate G4LogicalVolume G4Material(name, atomic_number, atomic_weight, density); G4Material(name, density, number_of_components); Defining a simple material: G4double atomic_weight = 39.95*g/mole; G4double density = 1.390*g/cm3; Materials & Geometry: • Geant4 detector geometry description is composed of three conceptual layers: Solid, Logical-Volume, Physical-Volume • users need to construct them directly in their user code (Detector Construction) by “new” • geometry description can be complex or simple (depends on what you are simulating, so maybe start with The Geant4 material model • The Geant4 material model follows the natural one: materials are made of elements and elements are made of isotopes • The 3 main classes to describe these objects are -G4Isotope: describes the properties of atoms (Z - atomic number, N - number of nucleons and A - molar mass) with unique name and index eV = electronvolt electronvolt = 1.e-6*megaelectronvolt megaelectronvolt = 1. eV = 1.e-6.

In contrast with Geant4, Gate does not use isotopic abundances. Element/Material is retrieved from Geant4 material database by its name: G4NistManager* manager = G4NistManager::Instance(); G4Element* elC = mananger->FindOrBuildElement("G4_C"); G4Material* matWater = mananager->FindOrBuildMaterial("G4_WATER"); The list of currently available material names can be found in the Geant4 User's Guide for G4Material. This class describes the macroscopic properties of matter: density, state, temperature, pressure, and macroscopic quantities like radiation length, mean free path, dE/dx, etc. Only the G4Materialclass is visible to the rest of thetoolkit and used by the tracking, the geometry and the physics.

STEP files do not include material information-, mesh volumes, and export them to GDML files. Materials are chosen from the Geant4 material database based

Therefore, our interface is supposed to manage materials in terms of both Geant4 and EGS4.

terms of constituent elements with specified weights. In output, Geant4 can choose the most appropriate unit to use. Just specify the category for the data (Length, Time, Energy, etc…): G4cout << G4BestUnit(StepSize, “Length”); StepSize will be printed in km, m, mm or … fermi, depending on its value Detector Description: Materials - Geant4 Course For those interested in direct access to Geant4’s materials should refer to the Geant4 User’s Guide: For Application Developers and the Geant4 User’s Guide: For Toolkit Developers for more detailed information. The material database contains two Geant4 structures called elements and materials that are used to define the physical properties of the atoms, molecules, and compounds.

eV = 1.e-6. So the units of the photon energies in G4MaterialPropertyVector are MeV and the length values are in mm. Chroma optical props are expresses in wavelengths in nm, so. Geant4 tutorials made by Steven Walton: We will go through tutorials and build our first Geant4 application, step by step First we will get a basic geometry, then get a visualization where we can run a beam through it, then we will focus on the physics Giovanni Santin - Defining materials - Geant4 tutorial, Paris 2007 5 Materials in Geant4 In nature, materials (chemical compounds, mixtures) are made of elements and elements are made of isotopes Three main classes in the Geant4 design – Isotopes G4Isotope – Elements G4Element – Molecules, compounds, mixtures G4Material 2015-04-01 · As Geant4 does not a priori come with functionality for adding generic properties to materials, NXSG4 keeps track of which crystal properties are associated to which G4Material instances by keeping an internal global map of G4Material addresses and their associated properties.
