A 1 TeV on 1 TeV p-barp collider at Fermilab using superferric magnets

A dedicated 1 TeV on 1 TeV p-bar p collider at Fermilab would allow both collider and fixed-target experiments to proceed in parallel with a corresponding increase in physics capability. A 2.5 T (nominal) superferric magnet ring of 2 km radium would also allow the development of magnets, enclosure and refrigeration systems for a very large 32 km radius - 20 TeV machine of the future. An attempt is made to estimate the cost of a prototype ring using many of the cost saving ideas put forth by those working on the 20 TeV machine. The magnets are based on Wilson's superferric magnet. The magnet system of the prototype, however, would not have the advantage of the economy of scale afforded by a machine 20 times larger. Cost estimates are given and a hypothetical magnet design and production scenario are assumed along with a Main Ring type lattice. Costs are then based as nearly as possible on the Energy Saver experience. The magnet for Fermilab prototype ring would be as close as possible to that used in the desert machine. The emphasis of the design would then be on low cost, ease of production, and reliability
