Gabriele Cosmo*** microyz example *** Author: S. Incerti et al. Date: 17 Apr. 2015 Email: incerti@cenbg.in2p3.fr **************************************************************** WARNING: This is a beta example, still buggy and under testing ! **************************************************************** (c) The Geant4-DNA collaboration. This example is provided by the Geant4-DNA collaboration. These processes and models are further described at: http://geant4-dna.org Any report or published results obtained using the Geant4-DNA software shall cite the following Geant4-DNA collaboration publications: Phys. Med. 31 (2015) 861-874 Med. Phys. 37 (2010) 4692-4708 This examples shows how to compute microdosimetry distributions in liquid water using exclusively Geant4-DNA physics processes and models. 1) Geometry A box of liquid water. 2) Incident particles Particles can be selected from the mycroyz.in macro as well as their incident energy. They are shot from the center of the box. 3) Physics The default Geant4-DNA physics constructor 2 is used in the PhysicsList class. 4) Scoring of enery deposition Energy depositions are scored in spheres randomly along the incident particle track. The user can select in the TrackerSD class: 1- the number of samplings (1000 by default) 2- the radius of the sphere (1.5 um by default) 5) The code can be run using: ./microyz microyz.in 6) Results can be analyzed after the run using: root plot.C The following microdosimetry quantities are plotted - f(y) - yf(y) - d(y) - yd(y) y is expressed in keV/um Plots are shown in lin-lin and log-lin coordinates. The following quantities are calculated: - Integral of f(y)dy - yF (in keV/um) - Integral of d(y)dy - yD (in keV/um) for linear lin-lin and log-lin plots, including normalization in the latter case.
