What NextWhat NextComplete the Installation & Commissioning of the Detector
Operate the Detector
Have great Discovery Physics
But also, …
Think how to and start R&D for the Upgrade
When? 2012 B-layer replacement 2016 ATLAS (Tracker) Upgrade for SLHC
What is going on… See next slides
What to do… Start to discuss today.

LayoutLayoutStrawman layout v.1 now has 4 Pixel Layers with a double B-layer option. Pixel Members in the Layout Advisory have been active in the last 2 months.
Two talks from Pixel at Liverpoo: Sasha - Lessons from b-tagging Performance of ATLAS Pixel Layout Vadim - Vertexing with Inner Detector
Message from Vadim’s talk: Vertexing is important for b-tagging and b-physics “Pixel” layout provides a ~3040% improvements in Z resolution, ~10-20%
improvements in R respect to strawman original layout (ver.0) Thinning of Pixel part of ID allows to increase significantly ID resolutions.
Strawman layouyt ver.1 Proposed Pixel Layout

Module ConceptsModule ConceptsMaurice showed some concepts for future modules:
Expect larger chips;
Active edges seem like a key development;
No MCC
cables & cooling
robotically placed, fully tested 1-chip modules.Wire bond to stave after placement.
Pre-tested stave structure with integrated bus and integrated, burned-in power adapters
present module
Active edge sensors to abut 1-chip modules w/o acceptance holes
+ Module control chip = 1 single module
Electrically 3 modules. No module control chip.

HMCFRP = High Module Carbon Reinforced Plastic (0,2÷0,3 mm)
Tubes made of a braided carbon (i.e. ‚stress free)hose (5÷10 W/mK) (0,1÷0,2) mm
Graphite Foam isotropic (180 W/mK)
Stave ConceptsStave ConceptsTwo Pixel Stave concepts (first time) presented: IVW, Milano, Wuppertal (see bottom left), LBNL (see bottom right)We should sit around a table to discuss and make an (unique) R&D proposal
~120-250 W/mK
~40-80 W/mK
Involute Lay-up (Ply Directions)
Fibers travel predominantly thru thickness rather than along laminate trajectory

CoolingCoolingThermal Management Meeting on Wed 6 Dec reported at the Workshop
Evaporative is the only explored. Possible gas candidates: C3F8:
Used in existing system → experience, Low pressure.
C2F6: Similar, but allows to cover low temperatures.
CO2: Low temperatures. High pressure. Low mass flows. Experience in LHCb, AMS, industry.
For environmental reasons we may be obliged to go to CO2 (C3F8 is 10000 times more effective than CO2 on Greenhouse effect)

Electronics IssuesElectronics IssuesKevin reported on the activities at LBL (Abder Mekkaoui) on the design of the input amplifier. 3 designs: “new fixed shaping”, “new ToT” and “optimised old ToT” designs. Submission foreseen Feb ‘07.He also reported some thinking on Control Circuitry, FE and Global (MCC) R/O architectures
Philippe Farthouat reported on 130 nm electronics plans, on the proposal of a Common R/O Architecture (MCC) for Pixel and Strips, GB opto links.
There will be a common workshop ATLAS-CMS devoted to electronics 19-21 March 2007 at CERN Announcement and program before Xmas

The Organization of the ATLAS Upgrade is given in: https://edms.cern.ch/file/690177/1/Upgrade_Org_PO.doc
Upgrade web page:
http://atlas.web.cern.ch/Atlas/GROUPS/UPGRADES/
The project office is part of TCn. The PO reports to TC/TMB and the Upgrade Steering Group. (EB when needed)
The ATLAS management/Upgrade Steering Group will define the concept of R&D resources , deliverables, Upgrade common funds etc. in the overall ATLAS concept.
The ATLAS resource coordinator, TC and ATLAS Spokesperson (s) with the Upgrade PO will develop the MOU for the deliverables of the Upgrade.
PO composed of a small core helps coordinate the effort relying on existing TC staff and functions. (i.e. No duplications)
A large fraction expected to come from the from major (outside) labs and universities.

ID LayoutID LayoutLayout Advisory Committee has been set up
Tasks: Develop list of performance goals, "Straw
man" layout with list of options, and evolve it to "Baseline layout"
Advise USG and PO on layout matters Membership
Sasha and Norbert added to the initial Pixel membership
Layout Group Anyone working on layout matters Simulation etc.
Developed a document on performance goals, definition of straw man, and options
Straw-man is now 4 pixel layers, 3 SS (Stereo) layers, 2 LS layers
Option: double b-layer
