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:

0027 1) Geometry
0028 A box of liquid water.
0029
0030 2) Incident particles
0031 Particles can be selected from the mycroyz.in macro
0032 as well as their incident energy.
0033 They are shot from the center of the box.
0034
0035 3) Physics
0036 The default Geant4-DNA physics constructor 2 is used in
0037 the PhysicsList class. Alternative constructor can be
0038 selected from the macro file microyz.in.
0039
0040 Livermore and Penelope physics lists can be used as well.
0041
0042 Tracking cut and maximum step size can be selected in microyz.in
0043
0044 4) Scoring of enery deposition
0045 Energy depositions are scored in spheres randomly
0046 placed along the incident particle track,
0047 using a weighted sampling.
0048
0049 The user can select the radius of the sphere in microyz.in using the command:
0050 /microyz/det/Radius X unit
0051 where X is the radius value and unit is specified.
0052
0053 5) The code can be run using:
0054 ./microyz microyz.in
0055
0056 6) Results can be analyzed after the run using:
0057 root plot.C
0058
0059 The distribution of y is shown by default.
0060
0061 The following quantities are calculated: yF and yD.
