class
AdiabaticCooling: public Module - #include <AdiabaticCooling.h>
Implements adiabatic cooling/heating due to advection.
-
class
ElectronPairProduction: public Module - #include <ElectronPairProduction.h>
Electron-pair production of charged nuclei with background photons.
This module simulates electron-pair production as a continuous energy loss.
Several photon fields can be selected.
The production of secondary e+/e- pairs and photons can by activated.
By default, the module limits the step size to 10% of the energy loss length of the particle.

class
EMTripletPairProduction: public Module - #include <EMTripletPairProduction.h>
Electron triplet pair production of electrons with background photons.
This module simulates electron triplet pair production of electrons with background photons for several photon fields. The secondary electrons from this interaction are optionally created (default = false). The module limits the propagation step size to a fraction of the mean free path (default = 0.1).
-
class
NuclearDecay: public Module - #include <NuclearDecay.h>
Nuclear decay of unstable nuclei.
This module simulates the nuclear decay of unstable nuclei using data from NuDat2. All decay modes are considered: alpha, beta+- and gamma decay, as well as proton- and neutron dripping. The resulting non-hadronic secondary particles (e+, e-, neutrinos, gamma) can optionally be created.
For details on the preprocessing of the NuDat2 data refer to “CRPropa3-data/calc_decay.py”.

class
PhotoDisintegration: public Module - #include <PhotoDisintegration.h>
Photodisintegration of nuclei by background photons.
-
class
PhotoPionProduction: public Module - #include <PhotoPionProduction.h>
Photo-pion interactions of nuclei with background photons.
-
class
Redshift: public Module - #include <Redshift.h>
Updates redshift and applies adiabatic energy loss according to the traveled distance.
-
class
FutureRedshift: public Module - #include <Redshift.h>
Updates redshift and applies adiabatic energy loss according to the traveled distance. Extends to negative redshift values to allow for symmetric time windows around z=0.
-
class
SynchrotronRadiation: public Module - #include <SynchrotronRadiation.h>
Synchrotron radiation of charged particles in magnetic fields.
This module simulates the continuous energy loss of charged particles in magnetic fields, c.f. Jackson. The magnetic field is specified either by a MagneticField or by a RMS field strength value. The module limits the next step size to ensure a fractional energy loss dE/E < limit (default = 0.1). Optionally, synchrotron photons above a threshold (default E > 10^7 eV) are created as secondary particles. Note that the large number of secondary photons per propagation can cause memory problems.
-
class
PhotonFieldSampling - #include <PhotonBackground.h>
Reimplementation of SOPHIA photon sampling. Naming and unit conventions are taken from SOPHIA to ease comparisions.
