---->0. INTRODUCTION.
|
|
|
|
The slowing example shows how to simulate slowing down spectra for electrons
|
|
in liquid water using the Geant4-DNA physics processes and models.
|
|
|
|
This example is provided by the Geant4-DNA collaboration.
|
|
|
|
It is described in S. Incerti et al. (2017), NIMB.
|
|
|
|
The Geant4-DNA 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
|
|
|
|
---->1. GEOMETRY SET-UP.
|
|
|
|
The geometry is a cube (World) made of liquid water (G4_WATER
|
|
material). Electrons are shot from the center of the volume.
|
|
|
|
---->2. SET-UP
|
|
|
|
Make sure G4LEDATA points to the low energy electromagnetic data files.
|
|
|
|
The code can be compiled with cmake.
|
|
|
|
It works in MT mode.
|
|
|
|
---->3. HOW TO RUN THE EXAMPLE
|
|
|
|
In batch mode, run:
|
|
|
|
./slowing slowing.in
|
|
|
|
The macro slowing.in shows how to use/define:
|
|
- number of threads
|
|
- Geant4-DNA physics constructors
|
|
- tracking cut
|
|
- atomic deexcitation
|
|
- histograms
|
|
|
|
---->4. PHYSICS
|
|
|
|
All Geant4-DNA physics constructors can be used.
|
|
|
|
---->5. SIMULATION OUTPUT AND RESULT ANALYSIS
|
|
|
|
The output results consists in a slowing.root file containing 3 histograms
|
|
of slowing down spectrum Phi/D (unit is /cm2/eV/Gy) as a function of energy
|
|
(log (E/eV)) for:
|
|
- all electrons (histogram number 1)
|
|
- primary electrons (histogram number 2)
|
|
- secondary electrons (histogram number 3)
|
|
|
|
This file can be easily analyzed using the provided ROOT macro
|
|
file plot.C (root plot.C).
