Update on ATLAS insertable B-layer LHCC Upgrade session CERN, September, 22nd 2009 G. Darbo - INFN / Genova Indico agenda page: http://indico.cern.ch/conferenceDisplay.py?confId=67640
IBL Project Status • Project approved by ATLAS • Project Leader endorsed by ATLAS CB (February 20th) • IBL has put in place its management structure (Management Board) – members nominated • ATLAS Institutes Participation • IBL Kick-off (July 8th) meeting with Institute’s Leaders to focus participation in the project. • Large interest in the project (~35÷40 institutes participated at the kick-off meeting and have shown interest in parts of the project) • Project cost evaluated and funding model proposed: 4.0 MCH (M&O-A), 5.6 MCH (M&O-B, new project) • Technical Design Report (TDR) • Main editor / technical editor (K. Einsweiler / M. Capeans) and chapter editors in charge • Few editor’s meetings since end of July, TDR foreseen for April 2010. • Memorandum of Understanding foreseen in “interim” form by the end of the year: • MoU will be signed after TDR (spring 2010)
IBL Organisation Structure • Membership • IBL Project Leader: G. Darbo • IBL Technical Coordinator: H. Pernegger • “Module” WG (2 Physicists): F. Hügging & M. Garcia-Sciveres • “Stave” WG (1 Phy. + 1 M.E.): O. Rohne + D. Giugni • “IBL Assembly & Installation” WG (2 M.E. initially, a Phy. Later): N. Hartman + R. Vuillermet • “Off-detector” WG (1 Phy. + 1 E.E.): T. Flick + S. Débieux • “Extra” members: • Ex officio: Upgrade Coordinator (N. Hessey), PO Chair (M. Nessi), Pixel PL (B. Di Girolamo), ID PL (P. Wells), Pixel Chair (C. Gößling) • Offline “liaison” Pixel Off-line coordinator: A. Andreazza • TDR editor (temporary): K. Einsweiler • Whole project divided into 4 working groups • IBL Management Board has 10 members, plus “extra” and ex-officio members. • Frequent meetings (every ~14 days) in this phase of the project. • IBL Management Board • Membership: • IBL PL + IBL TC • 2 coordinators from each WG • Plus “extra” members • Module WG • (2 coordinators) • FE-I4 • Sensors • Bump-Bonding • Modules • Test & QC • Irradiation • Stave WG • (1 Phys + 1 Eng.) • Staves • Cooling Design & Stave Thermal Management • HDI • Internal Services • Loaded Stave • Test & QC • IBL Integr.-Install. • (2 Eng.) • Stave Integration • Global Sup. • Beam Pipe (BP) • Ext.services inst. • IBL+BP Installation • Cooling Plant • Test & QC • Off-detector • (1 Phys + 1 E.Eng.) • Power • DCS • ROD • Opto-link • Ext.serv.design/proc. • Test Beam • System Test
Sensor • To put here: • 3 sensor technologies to the prototype phase – decide end of 2010 • Progresses in the development – pick up from sLHC R&D efforts • How to converge – engineering set of specifications • Have ~3 slides on sensors
FE-I4 • Put here: • Status • Submission review in November • 1 or 2 slides
Stave Design • To put here • Layout (preferred) • Motivate the need of a small beam pipe: tight clearance, gaining 0.5 cm is large respect the available space between BL and present beam pipe, beam pipe bake-out need space for IBL safety (show thermal simulation), use an IBL PST to simplify insertion…. • Show developments: • Pipe, Thermal Management, Fittings, options • Goal to reduce material budget from 2.7 to 1.5 %X0 • ~2-3 slides
Schedule • To put here • Plan to install in 2014, even if not sLHC phase I: • IBL as safety insurance for the present IBL • Cannot be much before without sacrificing performance, Need new technology development (Sensor, FE-I4, Staves) • From the machine: • Need to synchronize a long shutdown (8 months) for IBL installation – in the shadow of machine element installation • Motivation for an IBL and not a new Pixel (CMS) • New technology do not allow a large production scale (2 years more) • Make a replacement of the pixel detector with old technology difficult to find collaboration to make, and also would slow down technology improvement needed for sLHC • CMS is faster in opening and inserting/connecting the new Pixel system
Some questions to the Machine • To put here (help from Marzio/Nigel) • Triplet optimisation will need a new TAS: what are the requirements? – what are the implications for the shielding? This could be a big impact on ATLAS! Implications for the forward muons • Smaller beam is needed for IB what are the implications of a larger TAS opening and a smaller beam-pipe (and IBL)? What are the concern for the IBL safety? • What else?
