DESCRIPTION:Speakers: Jose Bernabeu (IFIC)\nThe ATLAS ITk Strip Detector f
 or the Phase-II LHC Upgrade\nATLAS-ITK Strip Collaboration\n\nThe inner de
 tector of the present ATLAS experiment has been designed and developed to 
 function in the environment of the present Large Hadron Collider (LHC). At
  the ATLAS Phase-II Upgrade\, the particle densities and radiation levels 
 will exceed current levels by a factor of ten. The instantaneous luminosit
 y is expected to reach unprecedented values\, resulting in up to 200 proto
 n-proton interactions in a typical bunch crossing. The new detectors must 
 be faster and they need to be more highly segmented. The sensors used also
  need to be far more resistant to radiation\, and they require much greate
 r power delivery to the front-end systems. At the same time\, they cannot 
 introduce excess material which could undermine tracking performance. For 
 those reasons\, the inner tracker of the ATLAS detector was redesigned and
  will be rebuilt completely.\n\nThe ATLAS Upgrade Inner Tracker (ITk) cons
 ists of several layers of silicon particle detectors. The innermost layers
  will be composed of silicon pixel sensors\, and the outer layers will con
 sist of silicon microstrip sensors. This contribution focuses on the strip
  region of the ITk. The central part of the strip tracker (barrel) will be
  composed of rectangular short (~ 2.5 cm) and long (~5 cm) strip sensors. 
 The forward regions of the strip tracker (end-caps) consist of six disks p
 er side\, with trapezoidal shaped sensors of various lengths and strip pit
 ches. After the completion of final design reviews in key areas\, such as 
 Sensors\, Modules\, Front-End electronics\, and ASICs\, a large scale prot
 otyping program has been completed in all areas successfully. We present a
 n overview of the Strip System and highlight the final design choices of s
 ensors\, module designs and ASICs. We will summarise results achieved duri
 ng prototyping and the current status of pre-production and production on 
 various detector components\, with an emphasis on QA and QC procedures.\n\
