5. IBL TDR G. Darbo / INFN Genova ATLAS CB – October 2010 5 Interim-MoU - Institutions There are 43 institutions in the IBL project Large interest for the sensor (22 Institutions) Full effort and funding requirements are covered 303 people have expressed their interest to contribute to the project many have already started to work. In most cases institutes contribute with money where also there is contribution with manpower. Status: Funding Agencies involved are sending their signed copies. The dead-line was end of August and we are waiting for the last ones to send them in.

6. IBL TDR G. Darbo / INFN Genova ATLAS CB – October 2010 6 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: ATLAS CB endorses 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.
