1. Characterisation of the Neutron Wall and of Neutron Interactions in Germanium-Detector Systems
Abstract : A Monte Carlo simulation of the Neutron Wall detector system has been performed using Geant4, in order to define optimum conditions for the detection and identification of multiple neutrons. Emphasis was put on studying the scattering of neutrons between different detectors, which is the main source of the apparent increase of the number of detected neutrons. READ MORE

2. Geant4 Monte Carlo Simulations of the International Space Station Radiation Environment
Abstract : A detailed characterization of the proton and neutron induced radiation environment onboard Columbus and the International Space Station (ISS) has been carried out using the Geant4 Monte Carlo particle transport toolkit. Dose and dose equivalent rates, as well as penetrating particle spectra corresponding to incident trapped protons, GCR protons, SPE protons and cosmic ray albedo neutrons are presented. READ MORE

3. Dosimetry Studies of Different Radiotherapy Applications using Monte Carlo Radiation Transport Calculations
Abstract : Developing radiation delivery systems for optimisation of absorbed dose to the target without normal tissue toxicity requires advanced calculations for transport of radiation. In this thesis absorbed dose and fluence in different radiotherapy applications were calculated by using Monte Carlo (MC) simulations. READ MORE

4. Benchmark of simulation of an ion guide for neutron-induced fission products
Abstract : Independent yield distributions of high-energy neutron-induced fission are of importance to achieve a good understanding of fission. Even though the mass and charge yield distributions of thermal neutron-induced fission are well known, there are few experimental data for high-energy neutron-induced fission. READ MORE

5. Quantum-state Selective Nuclear Decay Spectroscopy
Abstract : This thesis focusses on the results of two experiments employing Penning traps to prepare pure beams of the 213Ra ground state and 127Cd, which were then studied with the decay-spectroscopy setup TASISpec. The experiments were conducted with SHIPTRAP at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, and JYFLTRAP at the IGISOL Accelerator Facility at the University of Jyväskylä, Finland.
