CERN 400 GeV Proton Storage Rings with Superconducting Magnets

A design is presented for 400 GeV proton-proton storage rings to be added to the CERN SPS. An electron (20-25 GeV) ring is also foreseen and possibilities for antiproton-proton collisions. Eight interaction regions are planned (six for p-p and two for e-p) with high luminosity and good flexibility for physics experiments.
