Strahltest und Bestrahlung von Silizium-Teilchendetektor Prototypen

In this diploma thesis the usability of particle detectors for their use in a large particle physics experiment is verified. For this verification they are used during a beamtest at the super proton synchrotron at CERN. First there is a description of the mode of operation and interactions of particles with the detectors, the readout system as well as the experiment and the characeristic damages of silicon particle detectors under irradiation. To analyze the data, software will be extended by fitting modules, calculation modules for signal to noise (SNR) ratio and new reporting modules. Additionally existing components will be modified to be able to analyze the data. Because there has been a speculation about errors accounted for by the fabrication process and because the behaviour of the detectors after irradiation is essential for characterisation of particle detectors, the detectors have been irradiated at an Co60 gamma source. This irradiation was followed by another beamtest. At the end there is an interpretation of the results according to the performance and effects of the irradiation as well as an interpretation according to the suspected manufactoring errors. Results also will be compared to electrical measurements that have been performed parallel to this thesis.
