Abstract
The inner detector of the present ATLAS experiment has been designed and developed to function in the environment of the present Large Hadron Collider (LHC). During the future High-Luminosity phase of the LHC (HL-LHC), the particle densities and radiation levels will exceed current levels by a factor of ten. The inner detector has been redesigned and will be rebuilt completely. The new ATLAS Inner Tracker (ITk) consists of several layers of silicon particle detectors. The innermost layers will be composed of silicon pixel sensors, and the outer layers will consist of silicon microstrip sensors. The production of the ITk is underway. This manuscript focuses on the strip region of the ITk, describing the system, the final design choices, and the production status of the different activities.
