7. Recent Activities in Pixel Upgrade C. Darbo INFN / Genova Pixel Plenary, 13 Dec 2006 7 Module Concepts Maurice 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. Ref.: Maurice Garcia-Sciveres / Pixel Module Concepts

Possible gas candidates:  C 3 F 8 :  Used in existing system → experience,  Low pressure.  C 2 F 6 :  Similar, but allows to cover low temperatures.  CO 2 :  Low temperatures.  High pressure.  Low mass flows.  Experience in LHCb, AMS, industry. For environmental reasons we may be obliged to go to CO 2 (C 3 F 8 is 10000 times more effective than CO 2 on Greenhouse effect) Ref.: Georg Viehhauser & Greg Halwell / Summary of Thermal Management ….

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. Ref.: David Lissauer / Project Office Review
