This examples shows how to compute microdosimetry distributions y, z in liquid water using exclusively Geant4-DNA physics processes and models.
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: \n Phys. Med. 31 (2015) 861-874 \n Med. Phys. 37 (2010) 4692-4708 \n J. Appl. Phys. 122 (2017) 024303
Geometry
A box of liquid water.
Incident particles
Particles can be selected from the microyz.in macro as well as their incident energy. They are shot from the center of the box.
Physics
The default Geant4-DNA physics constructor 2 is used in the PhysicsList class. Alternative constructor can be selected from the macro file microyz.in
Livermore and Penelope physics lists can be used as well.
Tracking cut and maximum step size can be selected in microyz.in
Scoring of enery deposition
Energy depositions are scored in spheres randomly placed along the incident particle track, using a weighted sampling.
The user can select the radius of the sphere in microyz.in using the command:
/microyz/det/Radius X unit
where X is the radius value and unit is specified.
Run
The code can be run using:
./microyz microyz.in
Results
Results can be analyzed after the run using:
root plot.C
The distribution of y is shown by default.
The following quantities are calculated: yF and yD.
