Accelerator physics issues 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 1/spl times/10/sup 34/ cm/sup -2/ sec/sup -1/ and an integrated luminosity of about 100 fb/sup -1/ per year. In this paper we present a summary of work conducted during a workshop and issues we feel are most important. Accelerator Physics issues and design aspects specific to both the high field and low field magnet technologies were studied, including the general accelerator parameters, beam stability issues, magnet field quality and the R&D needed to relax the accelerator component tolerances. This paper summarizes the accelerator physics R&D the VLHC Accelerator Physics Working Group members are undertaking.
