Popis: Following successive upgrades of the CERN Large Hadron Collider (LHC) until approximately 2025, the High Luminosity LHC (HL-LHC) is expected to deliver pp collisions of centre-of-mass energy s = 14 TeV with a levelled peak luminosity in excess of 5 × 10 34 cm − 2 s − 1 and an integrated luminosity of order 300 fb − 1 per year. The ATLAS Collaboration intends to replace the existing Inner Tracking Detector by a new tracker, with readout electronics as well as silicon pixel and strip sensor technology capable of maintaining the excellent mechanical and electrical performance of the existing tracker in the severe radiation and high collision rate environment of the HL-LHC. The super-module integration concept extends the proven design of the existing barrel silicon strip tracker to the HL-LHC, with double-sided stereo silicon micro-strip modules assembled into a low mass local support structure. The first phase of the Super-Module R&D programme has been successfully completed, demonstrating the feasibility of the Super-Module concept. A summary is made up of the key prototype mechanical and electrical results of the R&D, as well as a short perspective of future developments.
