Lessons learned in the IBL project

摘要

The ATLAS experiment is ready for Run Ⅱ of the LHC with improved tracking performance thanks to the installation of a new Pixel Detector layer, called the Insertable B-Layer (IBL). The IBL was installed in May 2014 located at only 3.3 cm radius from the beam axis and has been successfully taking data since the beginning of Run Ⅱ in June 2015. An overview of the lessons learned during the IBL construction will be presented, focusing on the challenges and highlighting the issues met during the production, integration, installation and commissioning phases of the detector.
