Design Study for a Staged Very Large Hadron Collider

摘要

Advancing accelerator designs and technology to achieve the highest energies has enabled remarkable discoveries in particle physics. This report presents the results of a design study for a new collider at Fermilab that will create exceptional opportunities for particle physics-a two-stage very large hadron collider. In its first stage, the machine provides a facilty for energy-frontier particle physics research, at an affordable cost and on a reasonable time scale. In a second-stage upgrade in the same tunnel, the VLHC offers the possibility of reaching 100 times the collision energy of the Tevatron. The existing Fermilab accelerator complex serves as the injector, and the collision halls are on the Fermilab site. The goals of this study are: To create reasonable designs for the Stage-1 and Stage-2 VLHC in the same tunnel; To discover the technical challenges and potential impediments to building such a facility at Fermilab; To determine the approximate costs of the major elements of the Stage-1 VLHC; To identify areas requiring significant R&D to establish the basis for the design.
