摘要：
After the successful start of the Large Hadron Collider (LHC) in November 2009 plans for a luminosity upgrade, called super-LHC (sLHC), are already advancing well. With a planned luminosity of 5 x 10(34) cm(-2)s(-1) the ATLAS detector has to cope with both a high instantaneous and integrated luminosity, providing a challenging environment for the tracking and vertexing detectors. Hence a new tracker is foreseen for the sLHC operation. As the radiation dose will increase according to the integrated luminosity, novel radiation hard detectors are required. A large R&D program is underway to develop silicon sensors with sufficient radiation hardness. In this article measurements of silicon strip sensors designed by the ATLAS Silicon Strip Sensor Upgrade Collaboration are presented. Both measurements of sensors irradiated to the expected sLHC fluences for different detector regions as well as comparisons between measurements of full size sensor properties and their technical specifications are shown. Furthermore the design challenges of the inner detector layout and support structures are presented.
