Abstract
In this contribution we discuss how to prepare some possible detectors - only silicon option being considered, for the new era of HEP challenges because the bulk displacement damage in the detector, consequence of irradiation, produces effects at the device level that limit their long time utilisation, increasing the leakage current and the depletion potential, eventually up to breakdown, and thus affecting the lifetime of detector systems. Physical phenomena that conduce to the degradation of the detector are analysed both at the material and device levels, and some predictions of the time degradation of silicon detectors in the radiation environments expected in the LHC machine upgrade in luminosity and energy as SLHC or VLHC, or at ULHC are given. Possible effects at the detector level after high energy cosmic proton bombardment are investigated as well. Time dependences of these device parameters are studied in conditions of continuous irradiation and the technological options for detector materials are discussed, to obtain devices harder to radiation.
