Estimated characteristics modification of silicon detectors due to their use at the LHC-accelerator and in AMS space conditions

In this talk, the phenomenological model developed by the authors in previous papers has been used to evaluate the degradation induced in high resistivity silicon detectors by pion and proton irradiation at the future accelerator facilities or by cosmic protons considering the continuous irradiation for ten years of work. The equations governing the degradation of the lattice are explicitly considered. The damage has been analysed at the microscopic level (defects production and their evolution toward equilibrium) and at the macroscopic level (only the changes in the leakage current of the p-n junction was considered). The rates of production of primary defects, as well as their evolution toward equilibrium have been evaluated considering explicitly irradiation field of the specified applications, by the type of the projectile particle and its energy. The influence of these defects on the leakage current density has been compared with experimental data from the literature, and predictions for the LHC radiation fields, as well as for space missions in the near Earth orbits have been done, in the frame of the Schokley-Read-Hall model.
