TL;DR: In this paper, the authors present an improved understanding of the macroscopic changes of the effective doping concentration based on identification of individual microscopic defects, results from irradiation with a mix of different particle types as expected for the sLHC, and the observation of charge multiplication effects in heavily irradiated detectors at very high bias voltages.
