1. NLC - The Next Linear Collider Project John Cornuelle 12/11/02 NLC Structure Cost Comparison ISG 9 Meeting December 10-13, 2002

2. John Cornuelle 12/11/02 Slide 2 NLC - The Next Linear Collider Project NLC Structure Cost Comparison ISG 9 NLC 2002 Current Cost Roll-Up (FY 2002 $) Total of $4,940M without Escalation or Contingency With Facilities Costs Incorporated Main Linac is 54.5% of the Total Main Linac Hardware is $1,470 M, or 30% of the Total Structures and Tap-Offs Are $255 M, or 5% of the Total

3. John Cornuelle 12/11/02 Slide 3 NLC - The Next Linear Collider Project NLC Structure Cost Comparison ISG 9 Cost of Structures and Tap-Offs Alone (Constant Gradient Machine) $ Millions

4. John Cornuelle 12/11/02 Slide 4 NLC - The Next Linear Collider Project NLC Structure Cost Comparison ISG 9 Cost of RF and Extra Length Constant RF Power per Structure $ Millions Note: Assumes That Gradient is Proportional to 1/(Structure Length)^.5.

5. John Cornuelle 12/11/02 Slide 5 NLC - The Next Linear Collider Project NLC Structure Cost Comparison ISG 9 Cost of RF, Length, and Electrical Power Constant RF Power per Structure $ Millions Note: “Fixed” Costs Include the Base Length Costs and the EDIA Costs. Electrical Power Costs Assume 140 MW at $40 per MW-Hour for 6,570 Hours for the 90 cm Structure NLC 2002.

6. John Cornuelle 12/11/02 Slide 6 NLC - The Next Linear Collider Project NLC Structure Cost Comparison ISG 9 Structure Cost Explanation Metal Parts are About 45% of Structure Cost –15% of the Structure/35% of the Part Cost are the Cells These are Constant for a Given Energy; Everything Else Varies With the Number of Structures –30% of the Structure/65% of the Part Cost are the Other Parts 70% of These Are the Coupler Parts –The Labor to Assemble the Couplers is About 10% of the Total Labor Even if the Metal Parts are Free, Half the Structure Cost is to Assemble and Test It Regardless of Length
