Design parameters for the Very Large Hadron Collider

The goal of the Very Large Hadron Collider (VLHC) is to extend the energy frontier beyond LHC. The proposed design center-of-mass energy for the VLHC pp collider is 100 TeV, with a luminosity of le34 cm/sup -2/ sec/sup -1/. At present accelerator designs and calculations are being carried out for two different magnet technologies, one using superferric magnets at 2 Tesla (T), the other using high-field design with B>10 T. This paper summarizes the accelerator parameters for these two designs. We discuss the design parameters that have the largest effects on the performance of the accelerator and therefore need careful optimization. (11 refs).
