Towards the construction of the ATLAS ITk Strip Endcap detector for the HL-LHC phase

To sustain the seven-fold increase in instantaneous luminosity of the High-Luminosity phase of the LHC, the ATLAS experiment will replace its current Inner Detector with a new all-silicon tracker detector. The Inner Tracker (ITk) will consist of a silicon pixel detector, surrounded by layers of silicon microstrip sensors. The production phase of the ITk is underway. This document presents an overview of the foreseen steps to build the forward regions of the ITk Strip detector, focusing on the loading of the silicon microstrip sensors on the support structures, and on the preparation for the integration of each structure in the final Endcap frame.
