Novel results on fluence dependence and annealing behaviour of oxygenated and non-oxygenated silicon detectors

This work presents the latest results on electrical properties degradation of silicon radiation detectors manufactured at IMB-CNM (Institut de Microelectronica de Barcelona) subjected to proton irradiation at CERN for high energy physics applications. The evolution of full depletion voltage and leakage current with fluence, as well as their annealing behaviour with time, were studied. The results obtained extend the previous understanding of the role played by technology and oxygenated material in hardening silicon radiation detectors. (15 refs).
