IBL TDRG. Darbo / INFN Genova ATLAS CB – October 20102

IBL Project – Main Steps2008: 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!

IBL Technical Design ReportATLAS 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

IBL TDRG. Darbo / INFN Genova ATLAS CB – October 20105

Interim-MoU - InstitutionsThere 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.

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.
