A Monte Carlo simulation study of collimators for a high-spatial

This document, together with the source code and the documentation Introduction to Geant4 - M.Asai (SLAC) - Oct.27, 2003 @ Fermi Lab 32 Processes in Geant4 In Geant4, particle transportation is a process as well, by which a particle interacts with geometrical volume boundaries and field of any kind. Because of this, shower parameterization process can take over from MATERIALS AND METHODS Geant4 code. Geant4 version 10.3 was used in this study. The physics lists recommended by Geant4 to simulate neutron transport problems are QGSP_BIC_HP, FTFP_BERT_HP, QGSP_BERT_HP, QBBC, QGSP_BIC, FTFP_BERT, and QGSP_BERT. Geant4 solution: impose a “range” production threshold – Range cutoff instead of energy cutoff – default = 1 mm Only one production threshold cut is uniformly set Production threshold is internally converted to an energy threshold, depending on particle type and material Geant4 has no default unit. To give a number, unit must be “multiplied” to the number.

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.

Geant4-based electromagnetic background model for the CRESST

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.
