IBL Slides G. Darbo – INFN / Genova CSN1, 22 November History of IBL Project - Time Line 1998: Pixel TDR B-layer designed to be substituted every 3 years of nominal LHC (300 fb -1 ): due to then available radiation hard sensor and electronic technologies. 2002: B-layer replacement became part of ATLAS planning and was put into the M&O budget to RRB. 2008: B-layer taskforce B-layer replacement cannot be done – Engineering changes to fulfil delayed on- detector electronics (FE-I3, MCC) made it impossible even in a long shut down. Best (only viable) solution: “make a new smaller radius B-layer insertion using technology being developed for HL-LHC prototypes”. This became the IBL. 2009: ATLAS started IBL project: February: endorsed IBL PL and TC April: IBL organization in place (Endorsed by the ATLAS EB) 2010: TDR and interim-MoU TDR is under approval in ATLAS Interim-MoU is collecting last signatures.
