Description

The planned SLHC-Upgrade will result in a 10 times higher luminosity and therefore higher radiation-damage to the silicon-detectors in the tracker-subsystem of CMS. The magnetic field inside the tracker causes a shift of chargecarriers inside the detector-silicon resulting in a displacement of the measured position to the real position of the particles track. The angle the carriers are shifted by is called the lorentzangle. In my diploma-thesis I measured lorentzangles in 3 materials: FZ-p-in-n, FZ-n-in-p and MCz p-in-n. The latter 2 were irradiated up to 10E16 neq/cm². Also, extensive measurements of non-irradiated sensors were done to compare the results with data from modells and simulations. The results of my work will be presented at this workshop.
