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?
2. Are luminosities of order 1033
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?
3. Is a superconducting accumulator ring
4. Can a single facility serve the needs
of the disparate physics programs?
5. How much would such a facility be likely
6. What R&D program would be required?
