NLC The Next Linear Collider Project NLC Structure

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

ISG 9 NLC - The Next Linear Collider Project NLC 2002 Current Cost Roll-Up (FY 2002 $) 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 NLC Structure Cost Comparison Total of $4, 940 M without Escalation or Contingency John Cornuelle 12/11/02 Slide 2

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

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

ISG 9 NLC - The Next Linear Collider Project 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. NLC Structure Cost Comparison John Cornuelle 12/11/02 Slide 5

ISG 9 NLC - The Next Linear Collider Project 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 NLC Structure Cost Comparison John Cornuelle 12/11/02 Slide 6
