POPAE - A 1000 Gev on 1000 Gev Proton-Proton Colliding Beam Facility

A proposal has been developed for the construction of a 1000 GeV on 1000 GeV colliding beam facility at Fermi National Accelerator Laboratory. To achieve the same 2000-GeV center-of-mass energy with a fixed target accelerator would require a beam of more than 2 × 106 GeV. The total circumference of the facility is 5520 m, including six straight sections, each 200 m long. Injection from the Fermilab main ring or Energy Saver/Doubler (ES/D) will be at the energy desired for interactions, thus avoiding the uncertainty, complication, and cost of accelerating very intense beams in the storage rings themselves. Each ring will require 570 superconducting dipole magnets, each 6.2 m long; the field required at 1000 GeV is 60 kG. For a proton current of 5A in each ring at 1000 GeV, the high-luminosity insertion is designed to give L = 4 × 1033 cm-2 sec-1. The proposal was developed during an intensive study from November 1975 to April 1976. This study drew not only on the experience of the CERN ISR2 and previous Fermilab designs, but also on studies of high energy storage rings made at Brookhaven National Laboratory (Isabelle)4 and at CERN (LSR).5
