Recent results for the CMS tracker silicon detectors

Abstract

The paper reports on a detailed study of the radiation resistance of Ô · on Ò silicon microstrip detectors for the CMS tracking system.From this study it is seen that the use of low resistivity substrates with 100 crystal lattice orientation promises excellent performance of the Inner Tracker after heavy irradiation in the LHC environment. Furthermore, the advantage of using detectors thicker than 300 m in the Outer Tracker is discussed together with experimental measurements on prototypes.
