0009 This examples shows how to compute microdosimetry
0010 distributions y, z in liquid water using exclusively Geant4-DNA
0011 physics processes and models.
0012
0013 This example is provided by the Geant4-DNA collaboration.
0014
0015 These processes and models are further described at:
0016 http://geant4-dna.org
0017 and in
0018 J. Appl. Phys. 122 (2017) 024303
0019
0020 Any report or published results obtained using the Geant4-DNA software shall
0021 cite the following Geant4-DNA collaboration publications:

0028 1) Geometry
0029 A box of liquid water.
0030
0031 2) Incident particles
0032 Particles can be selected from the mycroyz.in macro
0033 as well as their incident energy.
0034 They are shot from the center of the box.
0035
0036 3) Physics
0037 The default Geant4-DNA physics constructor 2 is used in
0038 the PhysicsList class. Alternative constructor can be
0039 selected from the macro file microyz.in.
0040
0041 Livermore and Penelope physics lists can be used as well.
0042
0043 Tracking cut and maximum step size can be selected in microyz.in
0044
0045 4) Scoring of enery deposition
0046 Energy depositions are scored in spheres randomly
0047 placed along the incident particle track,
0048 using a weighted sampling.
0049
0050 The user can select the radius of the sphere in microyz.in using the command:
0051 /microyz/det/Radius X unit
0052 where X is the radius value and unit is specified.
0053
0054 5) The code can be run using:
0055 ./microyz microyz.in
0056
0057 6) Results can be analyzed after the run using:
0058 root plot.C
0059
0060 The distribution of y is shown by default.
0061
0062 The following quantities are calculated: yF and yD.
