Abstract:

To extend the physics potential of the Large Hadron Colider (LHC) at CERN, upgrades of the accelerator complex and the detectors towards the Super-LHC (sLHC) are foreseen. The upgrades, separated in Phase-1 and Phase-2, aim at increasing the luminosity while leaving the energy of the colliding particles (7 TeV per proton beam) unchanged. After the Phase-2 upgrade the average luminosity will be a factor of 5-10 higher than the design luminosity of the LHC. Due to the increased track rate and extreme radiation levels for the tracking detectors, upgrades of the detectors are necessary. At ATLAS, one of the two general purpose detectors at the LHC, the current inner detector will be replaced by an all-silicon tracker. This article describes the plans for the Phase-2 upgrade of the silicon strip detector of ATLAS. Radiation hard n-in-p silicon detectors with shorter strips than currently installed in ATLAS are planned. Results of measurements with these sensors and plans for module designs will be discussed.
