      abstract     = {This is the first of two Technical Design Report documents
                      that describe the upgrade of the central tracking system for
                      the ATLAS experiment for the operation at the High
                      Luminosity LHC (HL-LHC) starting in the middle of 2026. At
                      this time the LHC will have been upgraded to reach a peak
                      instantaneous luminosity of $7.5x10^34$ $cm^[-2]s^[-1],$
                      which corresponds to approximately 200 inelastic
                      proton-proton collisions per beam crossing. The new Inner
                      Tracker (ITk) will be operational for more than ten years,
                      during which ATLAS aims to accumulate a total data set of
                      3,000 $fb^[-1].$ Meeting these requirements presents a
                      unique challenge for the design of an all-silicon tracking
                      system that consists of a pixel detector at small radius
                      close to the beam line and a large-area strip tracking
                      detector surrounding it. This document presents in detail
                      the requirements of the new tracker, its layout and expected
                      performance including the results of several benchmark
                      physics studies at the highest numbers of collisions per
                      beam crossing. The design, construction and expected
                      performance of the large-area silicon-strip tracker are set
                      out in detail. These include the results of measurements of
                      prototype modules and associated support structures and the
                      plans for their mass production. A short description is
                      given of the state of the development of the pixel tracker,
                      which will be presented in detail in the second Technical
                      Design Report document one year from now. This document will
                      also describe the management of the project, its schedule
                      and major milestones. The costs of the new tracker and the
                      collaboration that plans to build it are also presented.},
