DESCRIPTION:Speakers: Koji  Nakamura (CERN)\nIn the high-luminosity era of
  the Large Hadron Collider\, the instantaneous luminosity is expected to r
 each unprecedented values\, resulting in up to 200 proton-proton interacti
 ons in a typical bunch crossing. To cope with the resulting increase in oc
 cupancy\, bandwidth and radiation damage\, the ATLAS Inner Detector will b
 e replaced by an all-silicon system\, the Inner Tracker (ITk). The innermo
 st part of the ITk will consist of a pixel detector\, with an active area 
 of about 13 m2. To deal with the changing requirements in terms of radiati
 on hardness\, power dissipation and production yield\, several silicon sen
 sor technologies will be employed in the five barrel and endcap layers. Pr
 ototype modules assembled with RD53A readout chips have been built to eval
 uate their production rate. Irradiation campaigns were done to evaluate th
 eir thermal and electrical performance before and after irradiation. A new
  powering scheme – serial – will be employed in the ITk pixel detector
 \, helping to reduce the material budget of the detector as well as power 
 dissipation. This contribution presents the status of the ITk-pixel projec
 t focusing on the lessons learned and the biggest challenges towards produ
 ction\, from mechanics structures to sensors\, and it will summarize the l
 atest results on closest-to-real demonstrators built using module\, electr
 ic and cooling services prototypes.\n\nhttps://indico.tlabs.ac.za/event/11
