- Simulation of Cosmic-Ray Propagation in the Near-Earth Environment
The interaction of cosmic-ray particles with the magnetic fields of the sun and Earth lead to modifications of their fluxes. To deduce physical findings from experiments measuring them, the effects of the magnetic fields must be considered quantitatively. In addition, absorption of cosmic rays and production of secondary particles in Earth’s atmosphere can also alter the observed particle spectra. The combination of both effects cannot be easily calculated, making precise numeric simulations necessary.
In this thesis, the influence of these effects on low-energy particles shall be investigated. The production and propagation of low-energy particles and antiparticles (e.g. antiprotons or antideuterons) are currently not well understood and need systematic studies. This requires the understanding of the production and transport mechanisms, as well as the properties of Earth’s magnetic field. The simulations shall be conducted using the PLANETOCOSMICS code based on the simulation framework Geant4.
- Acquire the necessary theoretical understanding of the interactions of comsic rays with magnetic fields and Earth's atmosphere
- Develop and extend a simulation framework in C/C++ and incorporate the newest results from accelerator-based experiments for particle interactions and particle production.
- Compare the output of the simulation to measurements conducted at different locations in Earth's proximity (startosphere, low Earth orbit, deep space).
Experience in C/C++ programming and data analysis is helpful, but not required.
