Abstract:
The use of semiconductor materials as detectors in high radiation environments, as to be expected in future high energy accelerators or in space missions, poses severe problems in long-time operations, due to changes in the properties of the material, and consequently in the performances of detectors.
This talk presents the major theoretical areas of current problems, and reviews the works in this field and the stage of their understanding, including author’s contributions
The mechanisms of interaction of the projectile with the semiconductor, the production of primary defects, the physical quantities and the equations able to characterise and describe the radiation effects, the equations of kinetics of defects are considered. Correlation between microscopic damage and detector performances and the possible ways to optimise the radiation hardness of materials are discussed.
