1. ATLAS Pixel Detector September 2002 N. Hartman LBNL 1 Pixel Support Tube: Cost and Production Schedule September 2002

2. ATLAS Pixel Detector September 2002 N. Hartman LBNL 2 PST Deliverables 3 Composite tubes 6 Bonded composite flanges Full Length insertion rails Mount pads at forward and barrel (8 total) PST Supports (8 flexures) Pixel detector supports (kinematic, 4 total) Heaters and EMI shielding (continuous over length) PST must be delivered as three bonded assemblies Barrel mount pads are bonded while in dry fit with SCT Forwards must be mounted to guarantee alignment All must be delivered by June ’04 Installation work costed in separate installation plan SCT installation is Sept. ’04

3. ATLAS Pixel Detector September 2002 N. Hartman LBNL 3 Full Schedule Note schedule is in calendar years, not fiscal Production estimate is rough (will know better by end of Q1 FY03) Based on delivery date of 6/1/04 to CERN SCT installation date 9/1/04 (3 months slack time)

4. ATLAS Pixel Detector September 2002 N. Hartman LBNL 4 Prototype Schedule Current Progress Note schedule is in calendar years, not fiscal

5. ATLAS Pixel Detector September 2002 N. Hartman LBNL 5 Prototype Items Shells –Completed Rails –Partially Complete – foot long rails have been made –Lead time of long rail tool is critical –Rail riders must be addressed Flanges –To be outsourced, not yet complete Hoop Stiffeners –May not be prototyped (fabricate during production phase only) –Schedule is already tight without them Mount Pads/Flexures –Mount pads require flat plate material from flange fabrication –If vendor cannot supply in time, must make mount pad material in house PST Assembly (bonding) –Designing bond tooling is critical item (lead time for machining) –Actual assembly can slip a little and overlap with long rail fabrication

6. ATLAS Pixel Detector September 2002 N. Hartman LBNL 6 Production Summary Prototyping –Continues through Q1 of FY03, but 3 month “slack” exists in Q2 of FY03, while full size mandrel is being machined –Q1 of ’03 is staffed with Research Assistant (FTE) and MT (1/2 FTE) –All production tooling produced in near-final form in prototype phase, except for mandrel –Prototype flange production contract covers tooling that will be used to fabricate production flanges as well (but under additional contract) Production –Begins in Q3 of FY03, Continues to Q4 of FY04 –Production time is staffed with MT (1/2 FTE) –PST Barrel constructed first, in case needed for dry fit with SCT earlier than expected, though many parts will already be made for all sections –Complete PST Delivered June of 2004

7. ATLAS Pixel Detector September 2002 N. Hartman LBNL 7 Important Milestones Production Readiness Review –December 9, 2002 – CERN Full Size Mandrel and Material Ordered –January 7, 2002 Production Material Delivered –February, 2002 Mandrel Delivered –March, 2002 Production Begins –April 1, 2002 Barrel PST Completed –September 14, 2002 Forward PST’s Completed –June 1, 2002 Fit-up with SCT (mount pads bonded in place?) –June, 2002 SCT/PST Installed –September, 2002

8. ATLAS Pixel Detector September 2002 N. Hartman LBNL 8 Potential Risks Prototyping –Problem with rail riders –Delay of bond or rail tooling –Delay of flange fabrication (contract) Production –Delays or problems in mandrel machining –Prototype delay eating into production time –Delay in working out mount pad bonding scheme with SCT –Delay in SCT schedule pushing back completion of PST (if dry fit is required for bonding to complete PST)

9. ATLAS Pixel Detector September 2002 N. Hartman LBNL 9 Cost Summary Costs in FY02 $K ETC02 to ETC03 very similar overall costs Schedule delay of about 6 months Production moved from FY03 to FY03/FY04 Prototyping extended into FY03
