|
|
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:

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.
