  In this contribution, the structural modifications of the material and the
degradation of devices is modelled and compared with experimental data for more
resistivities, temperatures, crystal orientations and oxygen concentrations,
considering the existence of the new primary fourfold coordinated defect,
besides the vacancy and the interstitial. Some estimations of the behaviour of
detectors in concrete environments at the next generations of high energy
physics experiments as LHC, SLHC, VLHC, or ULHC are done.
