Storage ring for enhanced antiproton production at fermilab

There is interest in the high energy physics community to upgrade the luminosity of the Tevatron Collider to a value greater than 1×10³³ cm^-2 sec^-1 per detector. The only feasible means to increase the luminosity by this factor of 10 over the design goal of the Main Injector project is to increase the antiproton production rate by almost the same factor. Using excess space in the Main Injector tunnel it is possible to build an additional storage ring whose purpose is to provide the flexibility necessary to produce and store the increased number of antiprotons. In this paper the motivation for this ring is discussed. The details of the scheme to recycle the antiprotons left over at the end of each Tevatron Collider store is also reviewed
