Radiatsionnye nagruzki na detektory tsentral'noj oblasti eksperimenta LHCb na LHC

One carried out numerical simulation of secondary radiation field generation within the centre of the CERN designed LHCb experiment on LHC. One demonstrates peculiar features of radiation field parameters depending on location of detectors in the course of experiment. One estimated radiation burdens governing operation of Si-detectors at the given background. The maximum tracker constitutes 10 sup - sup 1 sup 0 Gy or 40 kGy/year for design basis luminosity of the LHCb experiment. It involves the necessity to replace detectors of central tracker during the experiment so it is reasonable to divide Si-elements of stations into several sections according to length
