Silicon Strip Detectors for the ATLAS HL-LHC Upgrade

To further extend the ultimate physics reach of the experiments at the Large Hadron Collider (LHC), a series of accelerator and experimental upgrades are planned in 2014 (phase 0), 2017 (phase 1) and 2022 (phase 2). The phase 2 machine upgrade, called the High Luminosity-LHC (HL-LHC), is foreseen to increase the instantaneous luminosity by a factor ten with a total integrated luminosity of $3000~\rm{fb^{-1}}$. The ATLAS experiment plans to build a new all-silicon tracker for HL-LHC operation which can cope with the predicted high particle rates and intense radiation doses. This article summarizes the plans and recent progress prototyping the silicon micro-strip section of the ATLAS HL-LHC upgrade. Results from measurements of miniature ($10 \times 10~\rm{mm^2}$) and full-size ($97.5 \times 97.5~\rm{mm^2}$) planar n-in-p FZ silicon sensors are shown. The first prototypes of different module concepts with highly integrated cooling and mechanical support structures are also described.
