PP1 Collar Sealing service ring Alignment wires IBL key Specs/ Params • 14 staves, <R> = 33.25 mm • CO2 cooling, T < -15ºC @ 0.2 W/cm2 • X/X0 < 1.5 % (B-layer is 2.7 %) • 50 µmx 250 µm pixels • 1.8º overlap in ϕ, <2% gaps in Z • 32/16 single/double FE-I4 modules per stave • Radiation tolerance 5x1015 neq/cm2 IST IBL Support Tube IBL Staves
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.

Interim-MoU - Institutions • 43 institutions in the IBL project • Large interest for the sensor (22 Institutions) • 300 people have expressed their interest to contribute to the project • The list of names is in Ch.11 of IBL TDR
Money Matrix (A.4) • Unknown covers the previously assigned contribution to UK. UK cannot commit until sensor decision, • The Annex 4 has been changed in the technology option with the addition of is Munich MPI (D-MPG) – 12 kCH for the IZM order.
Institutes and Contributions to IBL Technology options refer to supplementary costs that are sensor technology specific and will be known before the definite MoU takes effect. 42 Institutes in the interim-MoU (few others are “observers” ). 14 Countries + CERN 9.7 MCH total project cost Note: the numbers in the table "are not final, nor are the suggested financial contributions yet firm, but are meant for a common overall discussion.”
Annex 5: IBL Payment Profile • Funding profile follows schedule for “ready to installation by end of 2014” • 2010 Expenditures: in large fraction for prototyping of FE-I4, sensors, modules, staves… • Two common contracts and several prototype costs already done in the framework of the interim-MoU.
IBL TDR – Endorsed by CB, LHCC • IBL TDR endorsed by ATLAS Collaboration Board (8/10/2010): • CERN-LHCC-2010-13, ATLAS TDR 19 • In printing 200 copies • Editorial team: M. Capeans (technical editor), G. Darbo, K. Einsweiller, M. Elsing, T. Flick,M. Garcia-Sciveres, C. Gemme,H. Pernegger, O. Rohne and R. Vuillermet. • IBL TDR presented to LHCC 21/9/2010: http://indico.cern.ch/conferenceDisplay.py?confId=107477 • The project has received very positive comments and TDR was considered a solid documents. • We expect some feedback from the reviewers (hope towards a formal approval) by end of the year/beginning of next year

Physics Performance 2 jets of 500 GeV event with 2 x 1034 pile-up Sound TDR section on Physics and Performance: • Pixel / IBL software Group – Coordinated by Attilio • Boosted in the last 3 months by the P & P TF – Chaired by Markus • Need to channel again the efforts in the Pixel / IBL Offline Software! Same event w/o pile-up IBL
Physics Performance b-tagging with pile-up 2 jets of 500 GeV event with 2 x 1034 pile-up • b-tagging performance crucial for: • New Physics (3rd generation !) • observation of H → bb through boosted WH production • Main conclusions of IBL performance Task Force: • performance at 2x1034 with IBL is equal to or better than present ATLAS without pile-up • w/o IBL and 10% B-layer inefficiency: b-tagging ~ 3 times worse at 2x1034 than today Same event w/o pile-up IBL Physics & Performance Task Force – M. Elsing et al. IBL b-tagging with pile-up & inefficiencies
The New Front-end Chip (FE-I4) 60 KGD / Wafer 20.2 mm • Reason for a new front-end chip • Increased radiation hard (> 250 Mrad) • New architecture to reduce inefficiencies (L=2x1034): faster shaping; not move hits from pixel until LVL1 trigger. • Smaller pixel size 50 x 250 µm2 (achieved by 0.13 µm CMOS with 8 metals) • Larger fraction of footprint devoted to pixel array (~90%) – little space for IBL envelope. • FE-I4 submitted on July 1st • More than 2 years of engineering work for a team of >15 Engineers/physicist • Largest HEP chip ever! 20.2x19.0 mm2, 87 million transistors! • 60 Known Good Dies (KGD) / 8” wafer. • 16 wafer engineering run – 3 received and under test. • Money contributions collected following interim-MoU share. • Engineering run cost > 500kCH 160 336 rows FE-I3 (Pixel) FE-I4 (IBL) 18 19 mm 80 columns
