  1. TDR of Insertable B-layer ATLAS CB, October 8th 2010 G. Darbo / INFN - Genova Indico agenda page: http://indico.cern.ch/conferenceDisplay.py?confId=80458

  2. IBL Project – Main Steps • 2008: Pixel B-layer taskforce: restore and improve tracking and b-tagging performance • Active for 6 months – report to the Bern ATLAS week  IBL concept • 2009: The IBL project sees the birth • Endorsement of IBL PL and TC (CB 20.02.2010) • IBL organization in place (management structure endorsed by EB 3.04.2010) • 8th of July: IBL kick-off meeting • ATLAS Institutes interested in the project invited (email to CB 28.04.2009) • 31 Institutes represented, 35÷40 Institutes shown interest. • 2009-10: The IBL project grows • Prototyping and design advance fast – progress followed in the IBL Community: • 4 General Meetings – several activity weekly meetings • Presented to ATLAS community • AW 2/2009, AW 7/2009, AW 10/2009, AW 2/2010, AW 7/2010, AW 10/2010 • 2010: The IBL project is consolidated (43 Institutions, 303 people committed) • Interim-MoU  collecting last signatures • TDR ready for approval!

  3. IBL Technical Design Report 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. ReviewersA. Andreazza, A. Catinaccio, A. Clark, N. Hessey, A. Lankford, M. Nessi, L. Rossi, S. Stapnes, G. Viehhauser, P. Wells and N. Wermes • ATLAS TDR includes: • Overview and motivation for the project • Study of the physics performance – Task Force (6/2010), led by M.Elsing, shows that IBL is crucial to recover the needed tracking and b-tagging capability  at 2x1034. • Technical description of the project with baseline and options for critical issues • Beam-pipe, extraction/insertion, installation • Organization of the project and resources • TDR versions: • 22.07.2010 – TDR editors first meeting • 17.03.2010 – 1st internal draft selected readers • 21.07.2010 – 2nd internal draft reviewers • 16.08.2010 – TDR incomplete draft IBL community and USG – deadline for comments 1.09.2010 • 07.09.2010 – TDR complete draft EB, IBL, USG • 15.09.2010 – Final draft for approval sent to CB • CERN-LHCC-2010-13, ATLAS TDR 19

  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. 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.
