Silicon Strip Detectors for the ATLAS HL-LHC Upgrade

AbstractTo 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(phase0), 2017(phase1) and 2022(phase2). The phase 2 machine upgrade, called the High Luminosity-LHC (HL-LHC), is fore seen to increase the instantaneous luminosity by a factor ten with a total integrated luminosity of 3000 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 theATLAS HL-LHC upgrade. Results from measurements of miniature (10×10 mm2)and full-size (97.5×97.5 mm2)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
