BEAM PARAMETERS AND LUMINOSITY TIME EVOLUTION FOR AN 80-KM VHE-LHC ∗

O. Dominguez, Frank Zimmermann

Abstract

The Very High Energy LHC (VHE-LHC) is a recently proposed proton-proton collider in a new 80-km tunnel. With a dipole field of 15-20 T it would provide a collision energy of 76-100 TeV c.m. We discuss the VHELHC beam parameters and compute the time evolution of luminosity, beam current, emittances, bunch length, and beam-beam tune shift during a physics store. The results for VHE-LHC are compared with those for HE-LHC, a 33-TeV (20-T field) collider located in the existing 27-km LHC tunnel. Presented at IPAC'13 Shanghai, 12-17 May 2013
