X-ray of FE-I4 size dummy bumped to dummy sensor Dummy sensor Dummy FE
ROD (BO + GE) • Redesign the ROD (Read-out Driver) architecture starting from the Pixel design: • Reason: components obsolescence, bottle neck of the Architecture, complexity in debugging due to mixed DSP / FPGA environment. • Smart Idea: • Move the embedded processing used for calibration (4 DSP/Board) to standard PC: use GB-ethernet • Responsibilities: • BO the ROD board, FPGA, PowerPC Programming • GE electrical-BOC to connect to FE-I4 modules without opto-link (debug the initial system) INFN responsibility

TDR: Status & Schedule • Motivation for delay in TDR printout: • LHC machine plans after Chamonix, luminosity profile, machine shut-downs impacted on IBL TDR. • Need of better documentation of Physics performance for the TDR ATLAS EB "IBL physics and performance taskforce”(M. Elsing, A. Andreazza) • The TF will reinforce the efforts to ensure the completion of the IBL performance studies for the IBL TDR by end of August. • TDR draft (Schedule) • First draft circulated to selected readers, comments received, being implemented. • Second review by experts: mid July. • TDR draft ready for distribution to IBL Collaboration: 2nd week of August • Final TDR ready: 4th week of August • Submission to LHCC: 1st week of September IBL (Staves) Ed Moise IBL in the Physics Simulation & in the Engineering CAD Rendering IouriiGusakov Existing B-layer IBL (Staves)
Physics & Performance TF • consolidate and extend present studies • single particle performance (pions and muons) • tracks in jets (100 and 500 GeVdi-jets, top, WH) • primary vertexing with high lumi. Pileup • b-tagging, especially redo high-pt jets studies • study different pileup scenarios • zero, 1034, 2*1034 and 3*1034 luminosity • estimate efficiency and fake rate vslumi • demonstrate how IBL helps for robust tracking in jets, with fakes, … • add emulation of Pixel/SCT readout problems • study robustness of tracking and how IBL recovers performance • Status • IBL geometry existing, motecarlo production ongoing • Checking results on single tracks, tuning jets and vertexing • TDR editing… keep deadline!!!
IBL Performance (TF Results) Simulation shows: • Clear improvement in impact parameter resolution (plot 1) • Specially in the region pT<10 GeV, that in ATLAS is dominated by multiple scattering • 50% improvement of rejection power in b-tagging (plot 2) • Performance are stable even if existing b-layer is off (plot 3).

Memorandum of Understanding • IBL Memorandum of Understanding (MoU) • BetweenThe ATLAS COLLABORATION, andFunding Agencies/Institutions of the ATLAS Collaboration constructing the IBL (for the ATLAS construction was between Institutes and CERN). • The MoU comprises all of the actions needed to construct and commission the IBL. The operation and maintenance of IBL is not a part of the present MoU and will be included, following its completion, within the M&O MoU framework. (IBL once delivered will be part of the Pixel Detector) • Annexes define: work sharing and responsibility, cost contribution, project organization and management structure. • IBL interim MoU – Why an interim MoU? • Ad Interim MoU until sensor technology is chosen (Planar Silicon / 3D Silicon / Diamond) - Decision on sensor technology (Spring 2011) – Sensor R&D and IBL communities work in tight collaboration to finalise a design matching IBL specification. • Consolidate interest of Institutes and availability of funds
Development of Interim-MoU • IBL (interim)-MoU Status: • “IBL Kick-off” meeting (8/7/2009) • Institutes express their interest in the IBL based on project WBS (Workpackage Breakdown Structure). • Institute Board created with the Institutes interested in the project • Extended Pixel IB (Meetings: 1/03/2010 and 18/06/2010) • Defined sharing of work, cost amongst Institutes/Funding Agencies (i-MoU annexes) • All project is covered by resources – need x-check with Funding Agencies (FA) • Status • Collecting feedback from FA on funding and general project support • Going to sign the interim-MoU? • INFN (BO, GE, MI, UD) • Quite active in the project, very good synergy and collaboration keeps up INFN visibility.
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.”
INFN Contribution to IBL • Total IBL cost: • 9741 kCH • Total INFN contribution: • 1400 kCH (14.4 %) • 1047 kCH CORE • 354 kCH M&O-A in-kind • ~100 kCHpresently on M&O-A could be deducted from INFN if cables (assigned as work responsibility) becomes in-kind contribution.
