IBL MoU Systems

Grouping used in the Annex 4 table

MoU Items

Grouping used in the Annex 1.x tables

annex 1 1 sensor 1 4
Annex 1.1: Sensor (1/4)
  • Sensor technology selected after prototyping with FE-I4
    • Prototypes with Planar, 3D and Diamond.
    • Once technology is selected the interim MoU will become the final MoU.
    • An Institute can leave the IBL project before signing the final MoU if is participation is “Sensor Technology Dependent”.
    • The Technology Option column in Annex 4 will cover the related and additional costs implied by the technology chosen.
  • In the prototyping cost only part of the real cost are covered:
    • Sensor prototype cost largely shared with sLHC R&D.
    • Cost in the IBL are for “extra wafers” and bump-bonding with FE-I4.
a1 1 sensors 2 4
A1.1: Sensors (2/4)
  • The quoted cost for production should cover Planar sensor or “low profile 3D”. More expensive solutions in the 3D, Diamond and/or thinner FE-I4 modules are maintained in the Technology Option until final decision.
a1 1 sensors 3 4
A1.1: Sensors (3/4)
  • Only work responsibility for prototyping in the iMoU.
a1 1 sensors 4 4
A1.1: Sensors (4/4)
  • Cost sharing for prototyping follows the “work responsibility” on the sensor technology.
  • Cost sharing for production selected to minimize “technology dependence” on funding source (see next slide).
annex 1 2 fe i4
Annex 1.2: FE-I4
  • FE-I4 assumes two engineering runs and final production of 3 batch of 24 wafers of the second version.
  • Work and cost includes wafer testing.
    • Including hardware (USBpix) and/or outsourcing for testing.
a 1 2 fe i4 2 4
A 1.2: FE-I4 (2/4)
  • In the item are:
    • FE-I4 version 1 (engineering run)
    • Fe-I4 version 2 (engineering run)
    • Hardware for single mo
a 1 2 fe i4 4 4
A 1.2: FE-I4 (4/4)
  • Cost sharing is different from version 1 and version 2 due to expected work participation of Geneva in the version 2.
annex 1 3 bump bonding
Annex 1.3: Bump-Bonding

A 1.3 Summary:

  • Deliverables:
    • Bump-bonding and QC for IBL
  • Prototype:
    • Vendor qualification.
a 1 3 bump bonding 2 4
A 1.3: Bump Bonding (2/4)
  • The cost was evaluated with rather conservative (40%) yield. Yield is probably better, but more advanced techniques would rise the costs.
a 1 3 bump bonding 3 4
A 1.3: Bump Bonding (3/4)


  • In the prototype phase the cost of FE-I4 wafer thinning and bump-deposition are in MoU item #3. The sensor wafer processing (UBM/bump-deposition) and flip chip is in MoU item #1.
  • Qualify the two vendors used by ATLAS Pixel - baseline AgSn - Technology backup Indium.  
  • KEK develops bump-bonding with Hamamatsu (possible option if the first two fail), participation to common procurement.

annex 21
Annex 2:

IBL Organization

    • IBL MB decisions and IB decisions
    • IBL PL and IBL TC responsibilities
    • Participation of the Institutes to the IBL: Pixel Institutes, new Institutes and participation through the Project Office.
    • Reporting of IBL PL and TC
    • Selection of IBL PL and TC (ATLAS rules), term of mandate.
    • Institutes voting for the IBL PL
  • Management Board
    • The IBL Management Board (MB) controls the execution of the project.
    • The IBL MB meets every two weeks in phone meeting and is chaired by the IBL PL and TC.
    • Meetings have closed participation to MB members and speakers could be invited to report on specific issues on request of the IBL MB.
    • The IBL MB uses indico and SharePoint to distribute material for discussion.
    • Minutes circulated to the IBL collaboration and Issue Tracking is the way the MB works.
  • Working Groups
    • The construction activities of the whole IBL project are divided into four working groups.
    • Each working group has two coordinators.
    • Sharing of responsibilities between the two coordinators in each working group is defined on the base on a mandate document.
    • The Working Group coordinators steer the activities they are concerned in periodic meetings that are largely in the form of phone conference.

Institute Board

    • The Institutions taking part in the project, in a direct way (as opposed through the UPO), with money and manpower, are part of the Institute Board (IB).
    • The IB is an extension of the Pixel IB and usually meets after the normal Pixel IB with the additional Institutions members in the IBL.
    • Major technology choices affecting the overall performance of ATLAS have to be brought forward to the collaboration as a whole for decision in the Collaboration Board.
    • Composition of the IB is ad-iterim until the IBL MoU is finalised.
  • IBL General Meetings
    • These meetings are held three or four times a year and constitutes the forum where discussions on any aspect of the Pixel project should take place.
  • Collaborative Tools & EDMS
    • To transmit the information in the IBL project is used a “Share Point” Collaborative Workspace.
    • Share Point is used during the phase of preparation of the documents in their final form. The approved document are referenced and posted in the EDMS structure.
    • Workgroup meetings and IBL General Meeting are on indico.
    • To transmit the information, a few open subscription (to ATLAS members) mailing lists.
annex 41
Annex 4

Technology options refer to supplementary costs that are sensor technology specific and will be known before the definite MoU takes effect.

So far, France, Italy and US have requested their shares to be moved from M&O to Project part.

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 payment profile
Annex 5: Payment Profile
  • The payment profile corresponds to readiness for installation by end of 2014
  • The main cost in 2010 are for prototyping: FE-I4, sensor, stave.
