The Desertron: Colliding Beams at 20 TeV

Abstract

With today's technology, the center-of-mass energy of proton-proton and proton-antiproton collisions can be extended by an order of magnitude beyond that achievable with machines presently in operation or under construction. Such a facility would open a vast new energy region which has been suggested theoretically to contain new kinds of particles and interactions. Several accelerator options, their rate capabilities, and their costs are described.
