Proposals for PEP and ISABELLE submitted

Two proposals for major high‐energy physics research installations were received by the Atomic Energy Commission this Spring. A 30‐GeV center‐of‐mass energy electron–positron colliding‐beam facility is the subject of a joint Stanford University and University of California proposal submitted in April. The other proposal, submitted in May, comes from Brookhaven National Laboratory and spells out the particulars of ISABELLE, a proton–proton intersecting storage accelerator where center‐of‐mass energies of up to 400 GeV would be available.
