Materials in Geant4 Three main classes in the Geant4 design Isotopes G4Isotope Elements G4Element Molecules, compounds, mixtures G4Material G4Isotope and G4Element describe the properties of the atoms: Atomic number, number of nucleons, mass of a mole, shell energies The documentation for this class was generated from the following files: source/source/materials/include/G4Material.hh source/source/materials/src/G4Material.cc Se hela listan på geant4.lngs.infn.it Materials in Geant4 •Geant4 materials (like those in the real world) –are made up of isotopes, elements, compounds (or molecules), mixtures of elements and/or compounds –can be solid, liquid or gas (sorry, no plasma) –may exist under various pressures, temperatures and densities 3 isotopes elements molecules/ compounds mixtures material, G4double : fraction ) Definition at line 447 of file G4Material.cc. Generated on Mon May 27 17:52:28 2013 for Geant4 by 1.4.7 Scintillator properties such as light yield and the primary decay time are typically provided by the manufacturer. However, the emission spectrum for fast and slow component are not typically provided. Can you please tell what’s the general practice to obtain the scintillator properties used in Geant4? • Shape, size, material, position and rotation can be parameterised, by implementing a concrete class of G4VPVParameterisation. • Reduction of memory consumption • Currently: parameterisation can be used only for volumes that either a) have no further daughters or b) are identical in size & shape. 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 I am writing a GEANT4 application using GDML that will require optical photon tracking.

The Geant4 simulated results of mass attenuation coefficients of composite materials have been compared with the experimental and theoretical XCOM data and a good agreement has been observed. GEANT4 is a Monte Carlo code originally implemented for high-energy physics applications and is well known for particle transport at high energies. The capacity of GEANT4 to simulate neutron transport in the thermal energy region is not equally well known.

Frequently Asked Questions on Physics This page explains several additional features available to users for the development of Geant4-DNA-based applications.. Material definition and density change; Geant4-DNA physics models can be used in liquid water defined in Geant4 as the NIST material G4_WATER.To do so, one may use the following lines in the DetectorConstruction class :

2.1.1 Materials definition Scintillator materials can be defined with a range of parameters in GEANT4, including: chemical composition, density, refractive index, scintillation yield, rise time, fall time, energy resolution, absorption length and scintillation energies. A set of fixed simulation parameters used for this study are outlined in
