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: Phys. Med. 31 (2015) 861-874 Med. Phys. 37 (2010) 4692-4708 J. Appl. Phys. 122 (2017) 024303

Geometry

A box of liquid water.

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.

Physics

The default Geant4-DNA physics constructor 2 is used in the PhysicsList class. Alternative constructor can be selected from 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 in the TrackerSD class the radius of the sphere (5 nm by default)

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.
