Summary
The costing algorithm used here was started at the time of the SSC proposal, was updated and presented at the Port Jefferson VLHC meeting in october 2000, and has been slightly modified again for this study. The method starts from a specified central field and aperture, and uses approximate formulae to design the dipole magnet cross sections. The required masses of superconductor, stabilizing copper, support stainless steel, and yoke are calculated, and the surface area of the cold mass determined. Costs per unit weight, or area/temperature, are assigned for each item and a linear cost added to cover the tunnel, supports, magnet ends, correctors, quadrupoles, survey etc. The unit costs were originally extracted from the SSC estimates, but have been inflated and modified since. They have no Intersection Point magnets, detectors, detector halls, EDIA, contingency, R and D or escalation. The assumed linear cost, including magnet ends, with the inflation factor, is 22 k$/m. If the aperture is small, as in the pipeatron, the magnets can be long, end costs reduced, and the packing factor improved. This expectation is confirmed by the recent Fermilab VLHC study. Using the total estimate from this study, the algorithm has been modified to include these effects.
