Event Reconstruction and Particle Identification for the Multi-purpose Active-target Particle Telescope

The Multi-purpose Active-target Particle Telescope (MAPT) is a newly developed radiation detector for space applications. The detector shall be used to monitor the radiation environment on spacecraft and satellites. It is most sensitive to low-energy protons and ions and can distinguish the particles by their interactions with the material of the detector.

In this thesis, the existing event reconstruction software shall be extended to allow the identification of different particle species. Therefore, the student has to implement a detailed model of particle interactions in matter into the analysis framework. The software shall be validated using existing data from a prototype experiment conducted in 2016 and simulations. 

 Tasks

  • Acquire necessary theoretical understanding of interactions of particles with matter.
  •  Implement the relevant physical processes in the analysis framework.
  • Validate the algorithms and analyze existing data, as well as simulated data.

 Prerequisites

Experience in C/C++ programming is helpful, but not required. An introductory course on C++ programming is offered.

Particle Identification for the Multi-purpose Active-target Particle Telescope

The Multi-purpose Active-target Particle Telescope (MAPT) is a newly developed radiation detector for space applications. The detector shall be used to monitor the radiation environment on spacecraft and satellites. It is most sensitive to low-energy protons and ions and can distinguish the particles by their interactions with the material of the detector.

In order to develop new particle-identification algorithms, a detailed simulation of the interactions of these particles and the response of the detector is needed. This can be achieved using the simulation framework Geant4, a common simulation tool for high-energy particle physics.

In this thesis, the response of the detector to different particle species shall be investigated. Therefore, the student has to conduct simulations and analyze the results systematically. For the analysis, an already existing analysis framework shall be used and extended.

 

Tasks

  • Acquire necessary theoretical understanding of interactions of particles with matter.
  • Conduct simulations of the detector using Geant4.
  • Systematically analyze the results and give a prospect of the separation power of the detector for different particle species.
  • Enhance the functionality of the MAPT analysis framework.

Prerequisites

Experience in C/C++ programming is helpful, but not required. An introductory course on C++ programming is offered.

Simulation of the Antiproton Flux in the Atmosphere

High energy cosmic-ray particles create antiprotons in interactions with molecules in the upper atmosphere. The flux characteristics of these antiprotons can be used to probe models of production and transport of particles in the atmosphere. Deviations of the measured flux from our models can indicate new mechanisms or sources of antiprotons.   

Several balloon-borne experiments have measured this particle flux in the last couple of years. In this thesis, these results shall be compared to simulations and to validate the current implementations of antiproton-production mechanisms in the high-energy simulation framework Geant4.

 

Tasks

  • Acquire necessary theoretical understanding of antiproton production and transport mechanisms in Earth’s atmosphere.
  • Conduct simulations of cosmic-ray interactions in the atmosphere using the simulation tool PLANETOCOSMICS, which is based on the high-energy simulation framework Geant4 (programming language C++).
  • Compare the results to measurements and interpret the findings.
