Abstract
We report selected results of laboratory measurements and beam tests of hea vily irradiated microstrip silicon detectors. The detectors were single-sid ed devices, produced by different manufacturers and irradiated with differe nt sources, for several total ionizing doses and fluences up to 4 x 10(14) 1-MeV-equivalent neutrons per cm(2). Strip resistance and capacitance, dete ctor leakage currents and breakdown performance were measured before and af ter irradiations. Signal-to-noise ratio and detector efficiency were studie d in beam tests, for different values of the detector temperature and of th e read-out pitch, as a function of the detector bias voltage. The goal of t hese test is to optimise the design of the final prototypes for the Silicon Strip Tracker of the CMS experiment at the CERN LHC collider.
