• As Fermilab plans its future in the post-LHC era, a dedicated high-intensity pbar storage ring in the <10-GeV range may offer the prospect of a broad program in nuclear and particle physics at relatively modest cost.  In many scenarios for Fermilab's future, a common element is a very high-intensity proton driver, which could make possible a substantial increase over present levels of antiproton production.  We held a workshop August 3 - 5, 2000 at Illinois Institute of Technology in Chicago to explore these ideas.

• Before the workshop we identified the following list of questions to addressed:

1. What are the physics topics of interest?  For example,
 
a. Is a hyperon CP-violation experiment at or below "Standard Model" sensitivity feasible?  What would be the dominant systematics and how could they be attacked?

b. Can hyperon beta decays be measured with sufficient precision to have significant impact on the determination of CKM matrix elements?

c. Can a compelling program in light-quark hadron spectroscopy be identified?

d. How important is it to extend precision c-cbar spectroscopy studies with p-pbar annihilation beyond what is currently possible at Fermilab?  What would such a program comprise and how should it be carried out?

e. Can such a facility make important contributions to the study of hadron interactions in the nuclear medium, for example, charmonium in nuclei?

f. What stopped-pbar physics will continue to be of interest?  Is a new facility (beyond the CERN AD) worthwhile?
 

2. Are luminosities of order 10³³ feasible?

3. Is a superconducting accumulator ring feasible?

4. Can a single facility serve the needs of the disparate physics programs?

5. How much would such a facility be likely to cost?

6. What R&D program would be required?

• The program contains links to transparencies presented by speakers or papers published in a volume of proceedings. The Proceedings are available in most HEP libraries and, on request in limited quantities.
