Proposal to Construct an anti-Proton Source for the Fermilab Accelerator

Abstract

We propose to build a small storage ring for the accumulation of antiprotons produced in an external target. Stochastic and electron qooling will be used to reduce the transverse and longi tudinal phase space of the antiprotons. The dynamics of stochastic and electron cooling will also be studied in this storage ring using circulating protons. The cooled antiprotons can be rein jected into the main ring or energy doubler ring: after simultane ous acceleration along with a proton bunch the accelerator will become a colliding pp machine with a center of mass energy range 10 32 l of 300-2600 GeV. Luminosities in the range 10 29-cm-2 sec are expected.

Guido Altarelli and the evolution of QCD

“…As an historical aside, I note that the discovery of the W and Z caused consternation in America, since the bold strategy of building the SppS at CERN initiated the transfer of the leadership in experimental high energy physics to Europe. This loss of primacy was especially bitter at Fermilab since the proton anti-proton machine had been originally proposed for the Fermilab main ring [47]. Although it might be a post-facto rationalization, the experiment would probably not have worked at Fermilab.…”

Overview of the Tevatron collider complex: goals, operations and performance

“…In 1976 Carlo Rubbia, David Cline, Peter McIntyre and colleagues proposed the implementation of a proton-antiproton collider at Fermilab [2] or at CERN, based on the conversion of an existing accelerator into a storage ring and construction of a new facility for the accumulation and cooling of antiprotons. The motivation was to discover the intermediate vector bosons, and the proposal argued that the requisite luminosity (∼10 29 cm −2 sec −1 ) could be achieved with a facility that would produce and cool approximately 10 11 antiprotons per day.…”

“…The antiproton source for a proton-antiproton collider at Fermilab was proposed in 1976 [1]. The proposal argued that the requisite luminosity (~10 29 cm -2 sec -1 ) could be achieved with a facility that would produce and cool approximately 10 11 antiprotons per day.…”
