  1. NLC Structure Cost Comparison ISG 9 Meeting December 10-13, 2002

  2. 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 Total of $4,940M without Escalation or Contingency

  3. Cost of Structures and Tap-Offs Alone(Constant Gradient Machine) $ Millions

  4. Cost of RF and Extra LengthConstant RF Power per Structure $ Millions Note: Assumes That Gradient is Proportional to 1/(Structure Length)^.5.

  5. 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. 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
