Abstract :
This paper investigates the performance of silicon microstrip detectors after heavy irradiation. Full-size prototype sensors (53 /spl times/ 64 mm/sup 2/) designed for the CMS Tracker have been irradiated with protons and extensively studied in the laboratory and using a beam of minimum ionising particles operated at low temperature as foreseen for the Large Hadron Collider. We present results of large statistics measurements of collected charge, noise, position resolution, and hit finding efficiency for these irradiated detectors.
